A prospective randomized controlled trial measuring satisfaction and parents stress after Gomco and Plastibell infant circumcision.

PURPOSE: To compare the physician and parental satisfactions between the two types of circumcision maneuvers used in our units, Gomco and Plastibell circumcision. METHODOLOGY: This study was performed from 2019 to 2021. A total of 190 children were circumcised either by Gomco or Plastibell procedure. Each child was evaluated during the procedure, immediately after the operation, and 1, 2, and 3 weeks after the procedure. Data were collected, statistically analyzed using SPSS version 25. RESULTS: A total of 190 children underwent circumcision from 2019 to 2021. Of the total 190, 98 children (51.6%) underwent circumcision by Gomco, while 92 (48.4%) underwent circumcision by Plastibell. Bleeding was significantly higher in Plastibell method, while excess skin was significantly higher in Gomco method (p value 0.048). Physician evaluation results show no significant difference between both methods in late physician evaluation. 23/92 (28%) of parents were not satisfied after Plastibell circumcision, compared to 8/98 (8.2%) of parents who were not satisfied with the results of Gomco circumcision (p value 0.002). CONCLUSION: Gomco needs a longer operative time, and Plastibell circumcision is less preferable by parents. There is no significant difference in physician satisfaction between the two procedures, but parents are less satisfied with Plastibell circumcision.

A Clinical Decision Aid to Support Personalized Treatment Selection for Patients with Clinical T1 Renal Masses: Results from a Multi-institutional Competing-risks Analysis.

BACKGROUND: Personalized treatment for clinical T1 renal cortical masses (RCMs) should take into account competing risks related to tumor and patient characteristics. OBJECTIVE: To develop treatment-specific prediction models for cancer-specific mortality (CSM), other-cause mortality (OCM), and 90-d Clavien grade ≥3 complications across radical nephrectomy (RN), partial nephrectomy (PN), thermal ablation (TA), and active surveillance (AS). DESIGN, SETTING, AND PARTICIPANTS: Pretreatment clinical and radiological features were collected for consecutive adult patients treated with initial RN, PN, TA, or AS for RCMs at four high-volume referral centers (2000-2019). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Prediction models used competing-risks regression for CSM and OCM and logistic regression for 90-d Clavien grade ≥3 complications. Performance was assessed using bootstrap validation. RESULTS AND LIMITATIONS: The cohort comprised 5300 patients treated with RN (n = 1277), PN (n = 2967), TA (n = 476), or AS (n = 580). Over median follow-up of 5.2 yr (interquartile range 2.5-8.7), there were 117 CSM, 607 OCM, and 198 complication events. The C index for the predictive models was 0.80 for CSM, 0.77 for OCM, and 0.64 for complications. Predictions from the fitted models are provided in an online calculator (https://small-renal-mass-risk-calculator.fredhutch.org). To illustrate, a hypothetical 74-yr-old male with a 4.5-cm RCM, body mass index of 32 kg/m2, estimated glomerular filtration rate of 50 ml/min, Eastern Cooperative Oncology Group performance status of 3, and Charlson comorbidity index of 3 has predicted 5-yr CSM of 2.9-5.6% across treatments, but 5-yr OCM of 29% and risk of 90-d Clavien grade 3-5 complications of 1.9% for RN, 5.8% for PN, and 3.6% for TA. Limitations include selection bias, heterogeneity in practice across treatment sites and the study time period, and lack of control for surgeon/hospital volume. CONCLUSIONS: We present a risk calculator incorporating pretreatment features to estimate treatment-specific competing risks of mortality and complications for use during shared decision-making and personalized treatment selection for RCMs. PATIENT SUMMARY: We present a risk calculator that generates personalized estimates of the risks of death from cancer or other causes and of complications for surgical, ablation, and surveillance treatment options for patients with stage 1 kidney tumors.

Acute Vasitis clinical picture mimicking inguinal hernia: Case report and review.

Acute Vasitis a rare condition, but one that can present with a diagnostic dilemma, if not recognized and managed appropriately, may lead to unnecessary surgical interventions with consequent morbidity for the patient. A 27 year old healthy male, presented with left scrotal pain associated with inguinoscrotal swelling. Physical examination revealed left scrotum tenderness and swelling extended along left inguinal area. CT showed multi loculated cystic fluid collection within left seminal vesicle. Acute Vasitis is a rare differential diagnosis for acute scrotum and This case report summarizes the importance of identifying it and how imaging can prevent unnecessary surgical intervention.

Impact of COVID-19 on endourology surgical practice in Saudi Arabia: A national multicenter study.

OBJECTIVE: To identify the impact of COVID-19 on endourology surgical practice in Saudi Arabia. METHODS: A retrospective study of seven tertiary hospitals from January 2019 to April 2019, and from January 2020 to April 2020 was performed. Records of urology outpatient department (OPD) visits and endourology procedures in the first third of 2020 were analyzed and compared with those in the first third of 2019, as well as, during the full curfew time, i.e. April 2020 versus April 2019. RESULTS: Number of OPD visits in the first third of 2020 and 2019 were 19 499 and 26 594, respectively (p<0.001). Number of OPD visits in April 2020 was 1512, with a 78.6% decrease compared to that in April 2019, and among them 1373 (90.8%) were teleclinics. Number of elective procedures in the first third of 2020 has decreased by 34.3% (from 3025 to 1988) compared to that in the first third of 2019 (p<0.001). There were 120 elective procedures in April 2020, 84.1% lower than that in April 2019. Percutaneous nephrolithotomy, shockwave lithotripsy, and transurethral resection of prostate procedures declined by 94.2%, 98.5%, and 93.8%, respectively. Most procedures were performed as day surgery (85.0%). Number of emergency procedures in 2020 have fallen by 9.3% compared to 2019 (p=0.286). Urolithiasis was the commonest pathology (52.6%) presented to the emergency room (52.6%). CONCLUSION: During COVID-19 pandemic, urology services slashed by >75%, including OPD visits and elective endourology procedures. Most hospitals have changed their strategic preventive measures by increasing the rate of teleclinics and day surgeries.

A Rare Presentation of Lisegang Rings in Adrenal Cavernous Hemangioma : Case Report and Literature Review.

BACKGROUND: Adrenal cavernous hemangiomas (AH) are benign nonfunctional vascular tumors rarely discovered as incidental findings on imaging studies or autopsies. This study presents a single case report of AH with another rare finding of the Liesegang ring. Also, we reviewed 73 case reports of cavernous adrenal hemangioma to provide an overview of AH's clinical characteristics. Case Report. A nonfunctional AH was incidentally discovered in a 59-year-old morbidly obese female patient with a 10-year history of hypertension and thyroidectomy. An abdominal computed tomography (CT) scan showed a left suprarenal mass of ∼16 cm in diameter. While the patient had no clinical manifestations from the hemangioma, all laboratory tests were within the normal values with no indication of a functional adrenal tumor. The mass was removed by open left adrenalectomy. The microscopic histological examination revealed a laminated structure with wide blood-filled spaces with a central core of necrotic and hemorrhagic changes, characteristic of a cavernous AH with the presence of a rare Liesegang ring. CONCLUSION: Although rare, AH should be considered as a differential diagnosis for adrenal masses. This is the first reported case of a cavernous AH with rare microscopic findings of the Liesegang ring.

Oncological outcomes in the management of cT1-T2 cN0 penile squamous cell carcinoma.

INTRODUCTION: Squamous cell carcinoma (SCC) of the penis is a rare disease comprising 1% of all male cancer. Options for the management of cT1-T2 cN0 penile SCC include partial penectomy (PP), considered the standard, and brachytherapy (BT), which offers acceptable local disease control and organ preservation. The purpose of our study was to assess and describe the oncological outcome for both treatments in a tertiary care center. METHODS: We performed a contemporary retrospective study of patients with early-stage penile cancer treated surgically or by BT at a tertiary center between 2000 and 2016. Demographic, management, and followup data were obtained from an institutional database. Descriptive statistics and survival analysis using Kaplan-Meier plots were calculated. Local and regional recurrences were compared in both groups (BT vs. PP). RESULTS: A total of 51 patients with cT1-T2N0 penile SCC treated with BT (35) and PP (16) were analyzed. Median followup was 37.1 (13.9-68) and 25.4 months (18-52.3) for the BT and PP groups, respectively. Recurrence developed in seven (20%) patients treated with BT. Median time to recurrence was 35.2 months (range 2.9-95.8). No recurrences were reported in patients treated with PP. Forty-four (86.2%) patients were alive with no evidence of disease at the last followup. Overall survival was 62.7%. Complications after primary tumor treatment were urethral stenosis (15.7%), penile necrosis (7.8%), and local infection (2%). CONCLUSIONS: PP provides acceptable local control with organ preservation in early-stage penile SCC. BT was able to offer organ preservation in 69% of men. Future prospective studies are needed to compare other organ-conserving treatment modalities with PP.

Serum Adipokines as Predictors for the Outcome of Prostate Biopsies at Early Stage Prostate Cancer Diagnosis.

PURPOSE: Elevated adipokines in patients with obesity and metabolic syndrome have been linked to increased risk of prostate cancer (PCa). The association between select serum adipokines and the outcome of prostate biopsies alone and in combination with clinical parameters at different early stages of PCa was investigated. PATIENTS AND METHODS: Clinical data and serum adipokines were retrieved from three retrospective cohorts representing men at different points in PCa detection: 1. Subjects with no prior biopsies (n=1061), 2. subjects with a prior negative biopsy (REDUCE trial, control arm) (n=1209), 3. subjects with low-risk PCa on active surveillance (AS) (n=154). Adipokines were chosen based on an unpublished pilot study and included: Resistin, Tumor Necrosis Factor-α, Interleukin-6, Monocyte Chemoattractant Protein-1, Hepatocyte Growth Factor, and Nerve Growth Factor. The primary outcome was the absence of PCa on biopsy and the secondary outcome was diagnosis of low-risk PCa fitting the criteria for continuing AS. Logistic regression analysis was used to assess the association of adipokines and negative and/or low-risk PCa at prostate biopsy. RESULTS: In men with no prior prostate biopsy or with prior negative biopsy, adipokines were not predictors of prostate biopsy outcomes on multivariable regression analysis controlling for known clinical variables. In the AS cohort, MCP-1 and Resistin were significant predictors of biopsy outcome on multivariable analysis (OR 0.20, 95% CI: 0.05-0.85, p= 0.03 & OR 0.30, 95% CI: 0.10 -0.86, p= 0.03). CONCLUSION: Our findings do not support a strong role for adipokines for predicting the outcome of prostate biopsies at any early stage in PCa diagnosis.

Malrotated right supernumerary kidney: Case report of a rare anomaly.

Supernumerary Kidney is a one of the rarest congenital renal anomalies with less than 100 cases reported in the literature. This accessory kidney has its own collecting system, vascular supply and well-defined capsule. We report a case of 18-year-old lady with a history of vague intermittent abdominal pain and has palpable abdominal mass who was found to have malrotated right supernumerary kidney with pelviureteric junction obstruction.

Transurethral Resection for the Treatment of an Inflammatory Myofibroblastic Tumor of the Urinary Bladder: A Case Report.

Inflammatory myofibroblastic tumors (IMT) of the urinary bladder is a remarkably rare bladder tumor. To this day, no standardized treatment protocol has been recognized. Here we report a case of bladder IMT in a 14-year-old girl presenting with urgency, frequency, and gross painless hematuria for a week. Complete excision of the bladder IMT was amenable with transurethral resection of bladder tumor (TURBT). Follow-up cystoscopy did not detect any recurrence. Minimally invasive bladder-sparing treatments are a valid option for treating IMT of the bladder.

Combined genetic and epigenetic alterations of the TERT promoter affect clinical and biological behavior of bladder cancer.

In urothelial bladder cancer (UBC), risk stratification remains an important unmet need. Limitless self-renewal, governed by TERT expression and telomerase activation, is crucial for cancer progression. Thus, telomerase activation through the interplay of mutations (TERTpMut ) and epigenetic alterations in the TERT promoter may provide further insight into UBC behavior. Here, we investigated the combined effect of TERTpMut and the TERT Hypermethylated Oncological Region (THOR) status on telomerase activation and patient outcome in a UBC international cohort (n = 237). We verified that TERTpMut were frequent (76.8%) and present in all stages and grades of UBC. Hypermethylation of THOR was associated with higher TERT expression and higher-risk disease in nonmuscle invasive bladder cancers (NMIBC). TERTpMut alone predicted disease recurrence (HR: 3.18, 95%CI 1.84 to 5.51, p < 0.0001) but not progression in NMIBC. Combined THORhigh /TERTpMut increased the risk of disease recurrence (HR 5.12, p < 0.0001) and progression (HR 3.92, p = 0.025). Increased THOR hypermethylation doubled the risk of stage progression of both TERTpwt and TERTpMut NMIBC. These results highlight that both mechanisms are common and coexist in bladder cancer and while TERTpMut is an early event in bladder carcinogenesis THOR hypermethylation is a dynamic process that contributes to disease progression. While the absence of alterations comprises an extremely indolent phenotype, the combined genetic and epigenetic alterations of TERT bring additional prognostic value in NMIBC and provide a novel insight into telomere biology in cancer.

Serum miRNA Predicts Viable Disease after Chemotherapy in Patients with Testicular Nonseminoma Germ Cell Tumor.

PURPOSE: Retroperitoneal lymph node dissection is recommended for residual masses greater than 1 cm after chemotherapy of nonseminomatous germ cell tumors. Currently there is no reliable predictor of post-chemotherapy retroperitoneal lymph node dissection histology. Up to 50% of patients harbor necrosis/fibrosis only so that a potentially morbid surgery has limited therapeutic value. In this study we evaluated the ability of defined serum miRNAs to predict residual viable nonseminomatous germ cell tumors after chemotherapy. MATERIALS AND METHODS: Levels of serum miRNA, including miR-371a-3p, miR-373-3p and miR-367-3p, were measured using the ampTSmiR (amplification targeted serum miRNA) test in 82 patients, including 39 in cohort 1 and 43 in cohort 2, who were treated with orchiectomy, chemotherapy and post-chemotherapy retroperitoneal lymph node dissection. miRNA levels were compared to clinical characteristics and serum tumor markers, and correlated with the presence of viable germ cell tumor vs fibrosis/necrosis and teratoma. ROC analysis was done to determine miRNA discriminative capacity. RESULTS: miRNA levels were significantly associated with disease extent at chemotherapy and they decreased significantly after chemotherapy. Conventional serum tumor marker levels were uninformative after chemotherapy. However, after chemotherapy miRNA levels remained elevated in patients harboring viable germ cell tumor in post-chemotherapy retroperitoneal lymph node dissection specimens. miR-371a-3p demonstrated the highest discriminative capacity for viable germ cell tumors (AUC 0.874, 95% CI 0.774-0.974, p <0.0001). Using an adapted hypothetical cutoff of 3 cm or less for surgical intervention miR-371a-3p correctly stratified all patients with viable residual retroperitoneal germ cell tumors with 100% sensitivity (p = 0.02). CONCLUSIONS: Our study demonstrates for the first time the potential value of miR-371a-3p to predict viable germ cell tumors in residual masses after chemotherapy. Prospective studies are required to confirm clinical usefulness.

A New Model to Predict Benign Histology in Residual Retroperitoneal Masses After Chemotherapy in Nonseminoma.

BACKGROUND: Postchemotherapy retroperitoneal lymph node dissection (pcRPLND) is indicated in testicular cancer patients with normalised or plateaued serum tumour markers and residual retroperitoneal lesions >1cm. Challenges remain in predicting postchemotherapy residual mass (pcRM) histology, which may lead to unnecessary surgery. OBJECTIVE: To develop an accurate model to predict pcRM histology in patients with nonseminomatous germ cell tumours (NSGCTs). DESIGN, SETTING, AND PARTICIPANTS: A retrospective review of 335 patients undergoing pcRPLND for metastatic NSGCTs to develop a model to predict benign histology in retroperitoneal pcRM. Our model was compared with others and externally validated. INTERVENTION: Chemotherapy and pcRPLND. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Multivariable logistic regression to evaluate the presence of benign histology, and fractional polynomials to allow for a nonlinear association between continuous variables and the outcome. The final Princess Margaret model (PMM) was selected based on the number of variables used, reliability, and discriminative capacity to predict benign pcRM. RESULTS AND LIMITATIONS: PMM included the presence of teratoma in the orchiectomy, prechemotherapy α-fetoprotein, prechemotherapy mass size, and change in mass size during chemotherapy. Model specificity was 99.3%. Compared with Vergouwe et al's model, PMM had significantly better accuracy (C statistic 0.843 vs 0.783). PMM appropriately identified a larger number of patients for whom pcRPLND can safely be avoided (13.9% vs 0%). Validated in external cohorts, the model retained high discrimination (C statistic 0.88 and 0.80). Larger and prospective studies are needed to further validate this model. CONCLUSIONS: Our clinical model, externally validated, showed improved discriminative ability in predicting pcRM histology when compared with other models. The higher accuracy and reduced number of variables make this a novel and appealing model to use for patient counselling and treatment strategies. PATIENT SUMMARY: Princess Margaret model accurately predicted postchemotherapy benign histology. These results might have clinical impact by avoiding unnecessary retroperitoneal lymph node dissection and consequently changing the paradigm of advanced testicular cancer treatment.

Replacing surveillance cystoscopy with urinary biomarkers in followup of patients with non-muscle-invasive bladder cancer: Patients' and urologic oncologists' perspectives.

INTRODUCTION: Urinary biomarkers are being developed to detect bladder cancer recurrence/progression in patients with non-muscle-invasive bladder cancer (NMIBC). We conducted a questionnaire-based study to determine what diagnostic accuracy and cost would such test(s) need for both patients and urologic oncologists to comfortably forgo surveillance cystoscopy in favour of these tests. METHODS: Surveys were administered to NMIBC patients at followup cystoscopy visit and to physician members of the Society of Urologic Oncology. Participants were questioned about acceptable false-negative (FN) rates and costs for such alternatives, in addition to demographics that could influence chosen error rates and costs. RESULTS: A total of 137 patient and 51 urologic oncologist responses were obtained. Seventy-seven percent of patients were not comfortable with urinary biomarker(s) alternatives to repeat cystoscopy, with a further 14% willing to accept such alternatives only if the FN rate were 0.5% or lower. Seventy-five percent of urologic oncologists were comfortable with an alternative urinary biomarker test(s), with 37% and 33% willing to accept FN rates of 5% and 1%, respectively. Forty-seven percent of patients were not willing to pay out-of-pocket for such tests, while 61% of urologic oncologists felt that a price range of $100-500 would be reasonable. CONCLUSIONS: This is the first survey evaluating patient and urologic oncologist perspectives on acceptable error rates and costs for urinary biomarker alternatives to surveillance cystoscopy for patients with NMIBC. Despite potential responder bias, this study suggests that urinary biomarker(s) will require sensitivity equivalent to that of cystoscopy in order to completely replace it in surveillance of patients with NMIBC.

Natural History of Complex Renal Cysts: Clinical Evidence Supporting Active Surveillance.

PURPOSE: We evaluated intervention rates, progression and cancer specific survival outcomes in patients with complex renal cysts in a single center experience. MATERIALS AND METHODS: We used the Montage™ radiology data mining system to retrospectively identify all reported cases of complex renal cyst at our institution from 2001 to 2013. The primary study end points were overall and cancer specific survival. The secondary end points included radiographic progression and upgrading, clinical progression and final histology on surgical pathology. RESULTS: We identified 336 patients with a complex renal cyst, of whom 185 (55.1%), 122 (36.3%) and 29 (8.6%) had Bosniak IIF, III and IV cysts, respectively. Median followup was 67.1 months (range 34.4 to 101.6). In the 332 patients with followup there was 1 cancer specific death (0.3%) and overall mortality was 6.2%. Ten (5.4%), 37 (30.3%) and 18 patients (62.1%) with Bosniak IIF, III and IV, respectively, underwent surgical or ablative intervention. The indication for intervention was predominantly age (intervention vs no intervention mean ± SD age 50.1 ± 15.9 vs 62.5 ± 13.9 years) and complexity. Surgery with radical and partial nephrectomy (23 patients or 35% and 37 or 57%, respectively) was most common and favorable final pathology was identified. Two treated patients experienced recurrence during followup. When excluding patients with von Hippel-Lindau syndrome, the cancer specific survival rate was 100%. CONCLUSIONS: Cancer survival and overall survival in patients with Bosniak IIF to IV renal cysts was high with only 1 cancer specific death. No cancer deaths were recorded in patients who did not undergo intervention. Reconsidering management guidelines for complex renal cysts is warranted, particularly consideration for initial surveillance of Bosniak III cysts.

Testosterone Responders to Continuous Androgen Deprivation Therapy Show Considerable Variations in Testosterone Levels on Followup: Implications for Clinical Practice.

PURPOSE: We determined whether men on continuous androgen deprivation therapy who achieve testosterone less than 0.7 nmol/l demonstrate subsequent testosterone elevations during followup and whether such events predict worse oncologic outcomes. MATERIALS AND METHODS: We evaluated a random, retrospective sample of 514 patients with prostate cancer treated with continuous androgen deprivation therapy in whom serum testosterone was less than 0.7 nmol/l at University Health Network between 2007 and 2016. Patients were followed from the date of the first testosterone measurement of less than 0.7 nmol/l to progression to castrate resistance, death or study period end. Study outcomes were the development of testosterone elevations greater than 0.7, greater than 1.1 and greater than 1.7 nmol/l, and progression to a castrate resistant state. Survival curves were constructed to determine the rate of testosterone elevations. Multivariate Cox regression analysis was done to assess whether elevations predicted progression to castrate resistance. RESULTS: Median patient age was 74 years and median followup was 20.3 months. Within 5 years of followup 82%, 45% and 18% of patients had subsequent testosterone levels greater than 0.7, greater than 1.1 and greater than 1.7 nmol/l, respectively. In 96% to 100% of these patients levels less than 0.7 nmol/l were subsequently reestablished within 5 years. No patient baseline characteristic was associated with elevations and elevations were not a significant predictor of progression to a castrate resistant state. CONCLUSIONS: Men on continuous androgen deprivation therapy in whom initial testosterone is less than 0.7 nmol/l frequently show subsequent elevations in serum testosterone. Such a development should not trigger an immediate response from physicians as these events are prognostically insignificant with regard to oncologic outcomes. Levels are eventually reestablished at less than 0.7 nmol/l.

Minimally invasive treatment of ureterovaginal fistula: A review and report of a new technique.

BACKGROUND: An iatrogenic ureterovaginal fistula (UVF) can be a consequence of difficult pelvic surgery. The patient must endure a long wait before having major surgery to reconstruct the injured ureter. Reports that address the minimally invasive treatment of UVF are limited, and are reviewed here. We introduce the concept of using a Memokath™ 051 stent (PNN A/S, Hornbaek, Denmark) as a promising minimally invasive approach for UVF. METHODS: We used PubMed, Science Direct, Google and the Cochrane Library to assemble appropriate evidence-based reference reports. The keywords used for the search were: 'Memokath', 'stent'; 'ureterovaginal fistula' and 'ureteral injury'. The review showed 42 relevant articles published up to September 2011. RESULTS: Ureteric stenting consistently stopped the vaginal leak of urine. The long-term results were not encouraging after removing the JJ stents at 3 months after insertion. Most patients had a recurrence of the vaginal leak of urine. The outcome was different with the Memokath stent, that remained in situ for a duration far exceeding that of the JJ stent. The Memokath stopped the vaginal leak of urine with no episodes of urinary tract infection and no evidence of stent migration. CONCLUSION: Long-term ureteric stenting has two advantages, in that it facilitates urine flow through the ureteric strictured segment down to the bladder, and it stops urine leakage along the fistula. It further promotes the resolution of the ureteric stricture and healing of the fistula. A duration of 3 months was inadequate when a JJ stent was used, whereas longer periods are possible with the Memokath stent. The optimum stenting period required for complete healing of a UVF remains to be defined. Long-term Memokath ureteric stenting can be an effective alternative and minimally invasive approach to conventional surgical repair in selected cases.
