Incidental prostate cancer after holmium laser enucleation of the prostate: Critical analysis of independent risk factors and impact on surgical outcomes.

Objectives: The objectives of this study are to evaluate the impact of incidental prostate cancer (iPCa) and its different grade group (GG) on the surgical outcomes of holmium laser enucleation of the prostate (HoLEP) and, furthermore, to assess the independent risk factors associated with the detection of iPCa. Patients or materials and Methods: A retrospective chart review was conducted at a single institution for HoLEP cases that were performed between 2017 and 2022. Patients with a preoperative diagnosis of prostate cancer and those without baseline prostate-specific antigen (PSA) levels within 1 year were excluded. Four hundred seventeen patients were divided into three groups: benign prostatic hyperplasia-377; clinically insignificant (GG 1)-29; and clinically significant prostate cancer (GG 2-5)-11. The preoperative parameters analysed included age, body mass index, race/ethnicity, use of 5-alpha-reductase inhibitors, PSA, prostate size, PSA density, and history of negative prostate biopsy. To evaluate the association between clinical and demographic variables, a multivariable-adjusted logistic regression analysis was performed. We also assessed intraoperative and post-operative outcomes among these three groups. Results: A total of 417 patients were analysed; 40 (9.6%) patients had iPCa, of which 29 (72.5%) and 11 (27.5%) were clinically nonsignificant and significant prostate cancer, respectively. Of all the demographic and preoperative variables analysed, hypertension was significantly associated with overall prostate cancer diagnosis (p < 0.05), and no other variable including patient age, preoperative PSA, PSA density, prostate size, or prior prostate biopsy were associated with increased risk of overall prostate cancer or clinically significant prostate cancer diagnosis. Most cases of iPCa were GG1, and 34 (85%) were managed with active surveillance. Conclusion: The rate of iPCa after HoLEP was 9.6%, with most cases being GG 1 (72.5%) and managed through active surveillance. Age, prostate size, baseline PSA, and prior negative prostate biopsies were not associated with increased risk of iPCa.

Inferior Vena Cava Thrombus Associated With Renal Cell Carcinoma With an Atypical Radiological Presentation: A Case Report.

Renal cell carcinoma (RCC) is characterized by the development of kidney masses, which can lead to various long-term complications. Among the extrarenal manifestations associated with RCC, the formation of a thrombus within the inferior vena cava (IVC) is particularly prevalent due to the substantial tumor burden imposed by the kidneys. In this report, we present an exceptional case involving an 80-year-old male patient who presented with an intravascular thrombus within the inferior vena cava (IVC), which originated from RCC. The diagnosis of RCC was conclusively established through core needle biopsy and subsequent tumor marker staining. Remarkably, despite the confirmation of RCC within the IVC thrombus through biopsy and tumor marker analysis, radiological assessments failed to reveal any discernible renal cell masses within the kidneys. The patient subsequently received treatment for RCC with a combination regimen of cabozantinib and nivolumab, which resulted in a noteworthy improvement in his clinical condition. The presentation of RCC in this report is notably atypical, given that the biopsy of the thrombus yielded definitive evidence of RCC while radiological investigations did not yield any indications of renal masses or a tumor burden within the kidneys that would typically be associated with RCC.

Seasonal Variation in Serum Testosterone Levels: Evidence from 2 Large Institutional Databases.

OBJECTIVE: Seasonal variations in testosterone levels have been reported in some studies, but the results are inconsistent. In this study, we aimed to determine if clinically relevant seasonal variability in testosterone levels exists using a large cohort of men from 2 different institutions, 1 located in an area with seasons (Pittsburgh, Pa) and 1 without seasons (Miami, Fla). METHODS: Using 2 institutional databases, testosterone levels were obtained for men ages 18-99 from 2010 to 2021 who had at least 2 morning testosterone levels drawn within a 2-year period. All samples were analyzed with liquid chromatography with tandem mass spectrometry. To avoid potential confounding by testosterone altering medications patients who were currently or previously on exogenous testosterone, endogenous testosterone-stimulating medications, testosterone-suppressing medications, and aromatase inhibitors were excluded from the study. RESULTS: There were 9495 and 16171 total testosterone levels measured from Miami and Pittsburgh, respectively, with all men having 2 or more levels. There was no statistically significant variation in testosterone levels for the overall cohort in Pittsburgh or Miami, respectively. Additionally, when stratified by age group, no individual groups were found to have significant seasonal variability. CONCLUSION: Our findings suggest that although there is differing total testosterone levels between men who reside in 2 different climates, there is no significant variability in testosterone levels between seasons. Therefore, testosterone levels can be checked and interpreted without the need to account for the season during which they were drawn.

Is Holmium Laser Enucleation of the Prostate Truly Size-Independent? A Critical Evaluation at the Extreme Ends of the Spectrum.

OBJECTIVE: To assess the outcomes of holmium laser enucleation of the prostate (HoLEP) at the extremes of the size spectrum, comparing whether the results are consistent for very large and small prostates. METHODS: A retrospective review of 402 patient charts was conducted to compare the outcomes of HoLEP in patients with prostate size ≤40 g (group 1), 41-200 g (group 2), and >200 g (group 3). Various preoperative, perioperative, and postoperative variables were collected. RESULTS: HoLEP showed comparable voiding outcomes among all 3 groups, although patients with small prostates had a higher International Prostate Symptom Score during follow-up (P = .022). We noted a higher rate of perioperative blood transfusion in patients with very large prostates (P = .019) and a higher rate of transient acute urinary retention (AUR) in group 1 when compared to group 3 (P = .048). Patients with smaller prostates had a higher rate of bladder neck stenosis and urethral strictures, but the differences were not found to be statistically significant. The incidence of other complications, length of hospital stay, and catheterization duration did not differ significantly among the groups. CONCLUSION: HoLEP has consistent and safe outcomes across a wide range of prostate sizes. Although, the risk of blood transfusion is higher in patients with very large prostates and the risk of transient AUR is greater in patients with small glands, the overall efficacy and safety of HoLEP are not significantly influenced by prostate size.

Sexual and Reproductive Health Among Men With Cystic Fibrosis.

Cystic fibrosis (CF) is a genetic disease caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) protein. Due to the distribution of the CFTR protein, CF presents with a heterogeneous phenotype. Men with CF may present with infertility due to congenital abnormalities of the vas deferens. In addition, they may experience testosterone deficiency. Today, they can father biological children with assisted reproductive technologies. We reviewed the current literature on the pathophysiology of these conditions, describe interventions that allow men with CF to conceive biological children, and provide recommendations for management of CF patients with reproductive health concerns.

Exploring the Legal Implications of Benign Prostatic Hyperplasia Surgeries in the United States: A Comprehensive Analysis of Two Decades of Lawsuits.

INTRODUCTION AND OBJECTIVE: The United States (US) currently faces a medical malpractice crisis, and a survey done in 2006 informed that 63% of urologists faced an average of 2.1 medical malpractice lawsuits. Surgery for benign prostatic hyperplasia (BPH) is performed by 95% of US urologists. Hence, we postulated that these procedures might be responsible for a substantial number of medical malpractice lawsuits. We examined claims related to BPH surgery in various US courts. MATERIALS AND METHODS: Data were collected from Westlaw and LexisNexis databases using the keywords "benign prostatic hyperplasia," "enlarged prostate," "surgery," and "malpractice" to search for cases from the entire US from January 2000 to December 2021. We extracted details such as the type of procedure, the plaintiff and defendant, the nature of the allegation, the alleged complications, the verdict, and the compensation amount. RESULTS: We found 30 cases in which the most common procedure was transurethral resection of the prostate (37%), with inadequate postoperative care as the most frequent reason for claims (33%). Urologists were the most frequently processed professionals (57%). The postsurgical outcomes that resulted in lawsuits were urinary incontinence (23%), erectile dysfunction (13%), and urinary retention (13%). Interestingly, 43% of the patients were inmates. Plaintiffs won only two (7%) cases: colon perforation after interstitial laser coagulation with Indigo laser and recto-urethral fistula after transurethral microwave therapy. CONCLUSION: Most lawsuits were related to postoperative incontinence and erectile dysfunction, with the verdict favoring the defendant in most cases. Inmates were the plaintiffs in a relatively high percentage of cases. Only two cases resulted in a plaintiff victory, wherein both cases presented unexpected and serious postsurgical complications.

Unusual Cause of Artificial Urinary Sphincter Malfunction: Device Entanglement Resulting in Urethral Constriction and Urinary Retention.

Urinary retention following placement of an artificial urinary sphincter (AUS) is not an uncommon complication. We describe a unique case of urinary retention due to AUS entanglement causing urethral constriction in a 72-year-old male. He presented to the emergency department postoperatively following AUS placement with pelvic pain and incomplete emptying. Eventual cystourethroscopy demonstrated severe extrinsic urethral constriction despite the deactivation of the AUS device. Surgical exploration revealed an unexpected looping of the occlusive cuff, causing urethral constriction. Although the precise cause is not clearly known, we suspect that it may have been related to the process of connecting the tubing at the level of the abdomen. Regardless of the underlying etiology, this case highlights a unique complication and supports an assessment of the cuff with direct perineal inspection prior to wound closure and/or with cystourethroscopy.
