Lower urinary tract symptoms (LUTS) are classically characterized as being related to storage (e.g., frequency, urgency, and nocturia) or flow (e.g., weak stream, intermittency, straining, and incomplete emptying). Conventional prescription medications such as α1-blockers and 5α-reductase inhibitors are used to treat progressive LUTS in men. Due to the adverse events associated with these prescription drugs, many patients with mild-to-moderate LUTS may decide to initiate treatment with non-prescription medications and/or dietary supplements. The lipidosterolic extract of Serenoa repens (LSESr), at a recommended daily dose of 320 mg/day, has been the focus of numerous peer-reviewed studies and review articles concerning the treatment of LUTS, from the first publication in 1983 by Boccafoschi to the most recent publication in 2021 by Russo. Although it seems improbable that the beneficial effect of LSESr reflects a placebo effect given the consistent degree of efficacy comparing various studies published in different countries over a span of almost 40 years, this has been the prevailing impression stemming from essentially three publications in the Western medical literature. In addition, despite publications reporting findings of almost identical efficacy using LUTS endpoints such as the International Prostate Symptom Score (IPSS), the quality of life score (QoL), and the peak urinary flow (Qmax) in comparing LSESr with the α-blocker tamsulosin or the 5α-reductase inhibitor finasteride, and despite the recognized acceptance of the hexane lipidosterolic extract product (Permixon^®) as an herbal medicine in Europe showing value in the treatment of LUTS, the use of LSESr remains controversial in the US. Contributing to such an opposing view in the US are the wide variability in quality, composition, and dosage of Serenoa products, the commercial prevalence of dried berry powder supplements, and the lack of awareness of a standardized Serenoa phytotherapy lipidosterolic profile. Can the controversy over the efficacy of LSESr in the context of LUTS be resolved? By understanding the main literature that has led to clinical practice guidelines for Serenoa repens for LUTS in Europe and the US, and by an in-depth analysis of the totality of the clinical literature concerning dose, extraction method, and quality of the Serenoa product used, it should be possible to answer this question. Given the extent of this global analysis, this report is presented in three sections. Part I introduces LUTS. What are the demographics of LUTS? What symptoms are assessed by LUTS, and how do we quantify LUTS? Why would a non-prescription item be a valuable consideration in LUTS treatment versus other treatment options? What is basic information about Serenoa repens, and what defines a standardized LSESr product? What are the published trials that have affected the acceptability of Serenoa repens in the treatment of LUTS? Finally, a major portion of Part I discusses the four major reviews of Serenoa repens versus LUTS that have influenced how it is accepted in the USA, in Europe, and in other parts of the world. Part I, therefore, lays the groundwork and is foundational for the important findings relating to LUTS and Serenoa repens that will be presented as Parts II and III in subsequent review articles.

Objectives: To examine the most recent literature and published science in determining any and all possible associations between pediatric obesity and pediatric urolithiasis. Methods: Retrospective literature review of pediatric stone formers with diagnosed stone disease and all associated risk factors. Peer-reviewed, published manuscripts from the past several decades were analyzed for risk factors associated with pediatric obesity such as diet, hypertension, and renal diseases. Comparing the pediatric obesity literature with the pediatric stone forming literature, any associations and correlations were derived and analyzed. Results: Despite the existing evidence that obesity is linked to stones in adults, the evidence remains unclear whether obesity plays a role in children. Nutritional discrepancies, in the setting of the obesity epidemic, have been shown to alter the risk profile of pediatric patients. Consistent with the published literature, and lack of consistent correlation with obesity and stone disease, is the knowledge that age, gender, geography, and climate may all play a role in the onset of pediatric obesity and may also be on the causal pathway toward pediatric urolithiasis. Conclusion: The manuscript demonstrates that there are a number of risk factors, congenital or acquired, that are associated with pediatric obesity. The mechanisms responsible for these associations may be on the causal pathway toward childhood urolithiasis. These mechanisms that underlie these associations need to be further investigated.

Background: The sexual health of young people is an especially important issue for national health policies. Adolescents, in fact, are at elevated risk for adverse sexual and reproductive health outcomes relative to their habits, sexually transmitted infections (STIs), sexual behaviour and teenage pregnancy. The aim of this study was to assess the knowledge about sexuality of students under the age of 18. Moreover, we aimed to explore the influence of sex education on sexual knowledge and behaviour. Methods: The participants were enrolled during a cultural exchange project in September 2019. After completing the questionnaire, all students took part in a sex education course performed by an urologist with expertise in sociology and psychology. The adolescents repeated the same survey in a web form in September 2020, one year after the course. Results: Analyzing the data, sex education lessons helped to improve students’ confidence in approaching all the issues of the questionnaire. Moreover, we observed a significant increase in the role of school as main source of information, while the role of the internet, media and family remained stable. Conclusions: This study encouraged the introduction of school-based sexual education policies, pointing to opportunities for structural early intervention programs. Full article

This is a critical review of the current literature data about sexual dysfunction as a potential side effect related to drugs commonly used for the treatment of Benign Prostatic Hyperplasia and Lower Urinary Tract Symptoms. In this narrative review, we analyzed data from the literature related to the development of sexual dysfunctions during the treatment of BPH or LUTS. Both α-blockers and 5-alpha reductase inhibitors (5-ARIs) can induce erectile dysfunction, ejaculatory disorders and a reduction in sexual desire. The sexual side effect profile of these drugs is different. Among the α-blockers, silodosin appears to have the highest incidence of ejaculatory disorders. Persistent sexual side effects after the discontinuation of finasteride have been recently reported; however, further studies are needed to clarify the true incidence and the significance of this finding. However, most of the published studies are affected by a weak methodology and other important limitations, with only a few RCTs available. Therefore, it is desirable that future studies will include validated tools to assess and diagnose the sexual dysfunction induced by these medications, especially for ejaculation and sexual desire disorders.

Familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC) is a rare tubulopathy characterized by renal loss of calcium and magnesium leading to progressive renal failure. The disorder is caused by variants to the tight junction proteins claudin-16 and -19. While rare, this disorder causes a significant burden to patients based on its clinical manifestations of various electrolyte abnormalities, nephrocalcinosis, and early progression to renal failure. In this report we describe the diagnosis of a novel variant of CLDN16 which clinically presented with severe hypomagnesemia, hypocalcemia, nephrocalcinosis, and renal failure. Full article

(1) Background: Pelvic organ prolapse (POP) is common among post-menopausal women affecting more than 25% in their lifetime—with 11% having a lifetime risk of undergoing an operation for a POP. In April 2019, the Food and Drug Administration (FDA) took surgical mesh for transvaginal use off the market due to safety and effectiveness concerns. This leaves colporrhaphy or colporrhaphy with bio-graft options for a POP surgical repair. (2) Case: In this report, we look at a case with anterior mesh erosion complicated by poor wound healing secondary to heavy tobacco use and how it was successfully removed and augmented with a Coloplast axis allograft dermis biological graft secured with an Anchorsure sacrospinous ligament/arcus tendineus fascia pelvis fixation device and prolene suture. (3) Results: After failing two prior surgeries to rectify the mesh erosion, a final procedure was performed using a biologic dermal graft and a double-layer closure to aid in protecting and increasing the integrity of the tissue. (4) Conclusions: Collectively, the patient and her surgeries highlight the difficult nature of complete mesh removal and how tobacco use can significantly affect the proper healing of surgical sites. The number of surgeries necessary to address the patient’s chief complaint and the resolution of her symptoms with the biologic graft supports the challenges one faces with mesh removal and poor wound healing secondary to tobacco use. This case illustrates that complicated transvaginal mesh erosion should initially be augmented with a biologic dermal graft secured via sacrospinous ligament/arcus tendineus fascia pelvis fixation and double-layer closure and not only if visible mesh removal alone fails.

(1) Introduction and Objective: Upper tract urothelial carcinoma (UTUC) is an uncommon disease, only accounting for 5–10% of all urothelial carcinomas. Current clinical practice guidelines encourage a risk-adapted approach to UTUC management, including lymph node dissection (LND) in patients with muscle-invasive or high-risk tumors. If pathological characteristics could be more accurately predicted from preoperative data, we could optimize perioperative management strategies and outcomes. The aim of this article is to present a detailed revision of preoperative predictors for muscle-invasive UTUC, locally advanced or advanced UTUC, as well as current indications, technique variations, and the reasons as to why LND should be offered to these patients. (2) Methods: We included any kind of studies related to information concerning UTUC, nephroureterectomy, LND, risk factors for recurrence, prediction tools and models for risk stratification. A literature search was conducted following medical subject headings (MeSh), Emtree language, Decs, and text words related. We searched through MEDLINE (OVID), EMBASE (Scopus), LILACS, and the Cochrane Central Register of Controlled Trials (CENTRAL) from inception to May 2021. Evidence acquisition was presented according to the PRISMA diagram. (3) Results: Preoperative risk factors for either muscle-invasive UTUC (≥pT2), extra urothelial recurrence (EUR), locally advanced disease, or high-risk UTUC can either be derived from ureteroscopic (URS) findings, urine cytology, URS biopsy, or from preoperative radiologic findings. It seems reasonable that LND may provide not only staging and prognostic information but also play a therapeutic role in selected UTUC patients. The patients who benefit the most from LND appear to be those with ≥ pT2 disease, because patients with tumors ≤ pT1 rarely metastasized to LNs. UTUC has characteristic patterns of lymphatic spread that are dependent on tumor laterality and anatomical location. Choosing the right patients for LND, designing and standardizing LND templates based on tumor location and laterality is critical to improve LN yield, survival outcomes, and to avoid under-staging or overtreatment. (4) Conclusions: Patients with muscle-invasive or non-organ-confined UTUC have an extremely high risk for disease recurrence and cancer-specific mortality (CSM). Preoperative factors and prediction models must be included in the UTUC management pathway in our clinical practice to improve the accurate determination of high-risk groups that would benefit from LND. We recommend offering LND to patients with ipsilateral hydronephrosis, cHG, cT1 at URS biopsy and renal sinus fat or periureteric fat invasion. The role of lymphadenectomy in conjunction with radical nephroureterectomy (RNU) is still controversial, given that it may result in overtreatment of patients with pTa-pT1 tumors. However, a clear benefit in terms of recurrence-free survival (RFS) and cancer-specific survival (CSS) has been reported in patients with ≥pT2. We try to avoid LND in patients with cLG, cTa, and no ipsilateral hydronephrosis if the patient is expected to be compliant with the follow up schedule. There is still plenty of work to do in this area, and new molecular and non-invasive tests are necessary to improve risk stratification. Full article

The relationship between prostatic chronic inflammation (PCI) and prostate cancer (PCa) is unclear and controversial. Some authors reported that a history of chronic prostatitis may be correlated with PCa induction, while others associate chronic inflammation with less aggressive disease or consider inflammation as a possible protective factor against PCa. Four different types of prostatitis are known: bacterial acute prostatic inflammation, bacterial chronic prostatic inflammation, abacterial prostatitis/chronic pelvic pain syndrome, and asymptomatic prostatic chronic inflammation. Prostatic inflammation is underestimated during daily clinical practice, and its presence and degree often go unmentioned in the pathology report of prostate biopsies. The goal of this report is to further our understanding of how PCI influences the biology of PCa. We investigated the main pathogenetic mechanisms responsible for prostatic inflammation, including the cellular response and inflammatory mediators to describe how inflammation modifies the prostatic environment and can lead to benign or malignant prostatic diseases. We found that prostatic inflammation might have a pivotal role in the pathogenesis of prostatic diseases. Details about PCI in all prostate biopsy reports should be mandatory. This will help us better understand the prostatic microenvironment pathways involved in PCa biology, and it will allow the development of specific risk stratification and a patient-tailored therapeutic approach to prostatic diseases.

(1) Background: The Adjustable Transobturator Male System (ATOMS) device is increasingly used to treat post-prostatectomy incontinence as it enhances residual urinary sphincteric function and allows continence recovery or improvement by dorsal compression of the bulbar urethra through a fixed transobturator mesh passage. The mode of action and the profile of the patients with best results are not totally understood. (2) Methods: Intraoperative urethral pressure measurements at different filling levels of the ATOMS device show increased urethral resistance and enhanced residual sphincteric activity. We evaluated whether the pattern of urethral pressure change secondary to serial progressive intraoperative filling of the cushion can predict postoperative results after ATOMS placement. (3) Results: The regression analysis showed a significant direct relationship between cushion volume and intraurethral pressure (p = 0.000). The median intraurethral pressure at atmospheric pressure was 51 ± 22.7 cm H2O, and at atmospheric pressure plus 4 mL was 80 ± 23.1 cm H2O). Cluster analyses defined a group of patients (n = 6) formed by patients with a distensible urethra and 100% continence after adjustment in contrast to another group (n = 3) with rigid urethras and 33% continence after adjustment. (4) Conclusions: As a part of its continence mechanism, the ATOMS device leads to continence by increasing intraurethral pressure owing to the stretching effect on the urethral wall caused by cushion filling that increases urethral resistance.

There have been few studies reported with conflicting results in the use of neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), redcell-distribution-width (RDW), etc. for predicting prognosis and differential diagnosis of adrenal tumors. The aim of this study is to investigate the role of inflammatory markers through a complete blood count, which is an easy access low-cost method, for the differential diagnosis of adrenocortical adenoma (ACA), adrenocortical carcinoma (ACC), and pheochromocytoma. The data of patients who underwent adrenalectomy between the years of 2010–2020 were retrospectively analyzed. Systemic hematologic inflammatory markers based on a complete blood count such as neutrophil ratio (NR), lymphocyte ratio (LR), NLR, PLR, RDW, mean platelet volume (MPV), and maximum tumor diameter (MTD) were compared between the groups. A statistically significant difference was found between the three groups in terms of PLR, RDW, and MTD. With post-hoc tests, a statistically significant difference was found in PLR and MTD between the ACA and ACC groups. A statistically significant difference was found between the ACA and pheochromocytoma groups in PLR and RDW values. In conclusion, it could be possible to plan a more accurate medical and surgical approach using PLR and RDW, which are easily calculated through an easy access low-cost method such as a complete blood count, together with MTD in the differential diagnosis of ACC, ACA, and pheochromocytoma.

Topical anesthetics are one of the first line therapeutical options for men with premature ejaculation (PE). Real-life PE management often involves a range of interventions including systemic drug treatments (such as off-label and on-label selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants, phosphodiesterase-5 inhibitors (PDE5Is)), topical anesthetic creams and sprays, and behavioral approaches. Among them, on-demand dapoxetine and lidocaine/prilocaine spray formulations are the only approved treatment options for lifelong PE. The earliest strategy to treat PE was based on the use of topical anesthetic agents. The rationale behind the use of anesthetics is that by reducing the glans penis sensitivity, the spinal and cerebral input of sexual arousal impulses may also be reduced. Oral SSRI proved to be effective to treat PE, but their high rate of side effects limit treatment adherence and both short and long term follow up data are lacking. Conversely, topical anesthetics have proved to increase ejaculatory latency, control, and sexual satisfaction in couple affected by PE with limited rates of adverse events. In this context, we aimed to perform a narrative review to summarize the most recent findings regarding the use of topical treatments for PE. Full article

Plasmacytoid variant of urothelial carcinoma is a rare subtype of urothelial carcinoma that has poor prognosis. We describe two cases of patients with the plasmacytoid variant of urothelial carcinoma (PVUC) who had initial response to neoadjuvant chemotherapy followed by radical cystoprostatectomy and lymph node dissection but presented with early relapse and disease progression manifesting with intestinal obstruction and peritoneal carcinomatosis. Tumor genomic sequencing revealed mutations and alterations in ARID1A, CDH1, PIK3CA, RB1 loss, and TERT promoter, as well as tumor mutational burden of 10 Muts/Mb treated with pembrolizumab with a minimal response. A further review of the literature regarding this rare variant is discussed here. Full article

The quality of life (QoL) concept now includes new aspects related to patients’ well-being because QoL has become more of a personal perception than an an objective and measurable entity. Here, we discuss the principal aspects of QoL-related aspects in urology and andrology by using a narrative review. Some aspects concerning the QoL are essential when managing uro-andrological patients. The aim of treatments should not only include the absence of disease or symptoms relief but also the improvement of a patient’s QoL with regard to his/her internal status and relationship with others. In this sense, any therapeutic approach should be based on the patient’s perspectives and not only on the instrumental and laboratory findings. Finally, we discussed the role of a patient’s sexual partner adding an extra dimension to the patient-centerd approach as part of the QoL concept in andrology. Full article

This study was undertaken to compare Fuhrman grading with World Health Organization/International Society of Urological Pathology (WHO/ISUP) grading and stereologically measured nuclear area in patients with Clear Cell Renal Cell Carcinoma (ccRCC) or Papillary Renal Cell Carcinoma (PRCC) and to evaluate the independent predictive value of Fuhrman, WHO/ISUP and stereologically measured nuclear area combined with necrosis in a series of patients with ccRCC in relation to cancer-specific survival. In all, 124 cases of ccRCC and PRCC were included. All slides were blindly scored by two trained pathologists according to the Fuhrman and WHO/ISUP grading systems. Nuclear measurements were performed on digitally scanned slides in Visiopharm^® and correlated to survival. Analysis of ccRCC and PRCC cases showed that application of WHO/ISUP grading resulted in a significant downgrading of cases from G2 to G1, when comparing with Fuhrman grading. Neither of these patients experienced progression. Cancer specific survival estimates in 101 ccRCC patients showed that WHO/ISUP grading was slightly superior in predicting cancer-specific survival. Novel models included WHO/ISUP grading and mean nuclear area (MNA) each of which combined with necrosis. Both demonstrated an increased ability to predict cancer-specific survival. The study demonstrates that WHO/ISUP grading provides superior prognostic information compared to Fuhrman grading and stereologically measured nuclear area. Necrosis in combination with either WHO/ISUP grading or MNA adds additional prognostic information. Full article
