Parental regret following decision for sons to undergo elective post-neonatal circumcision.

INTRODUCTION: The reasons for performing a circumcision among males after the neonatal period are usually cultural or medical. We aimed to evaluate parental regret for providing consent and to identify factors associated with such regret. METHODS: Included were the parents of males aged 6 months to 18 years who underwent circumcision under general anesthesia at a single center between 2/2017 and 01/2023. Those who underwent additional surgical procedures during the same session were excluded. Parents responded telephonically to the Decision Regret Scale (DRS) questionnaire. Regret was classified as none (0 points), mild (1-25) or moderate-to-strong (26-100). Surgical and demographic data were retrieved for comparison to DRS scores and identification of predictors of parental regret. RESULTS: In total, 201 of the 265 suitable patients met the inclusion criteria. Parents of 130 patients (65% response rate) whose average age was 5.06 (IQR 1.58,7.53) years completed the DRS questionnaire (study group). The average time since surgery was 41.8 (IQR 25.4,59.3) months. Forty surgeries were undertaken for cultural reasons and 90 for medical considerations. Eighteen parents reported regret (15 mild and 3 moderate-to-strong) for their decision to consent to their son's circumcision. The time from responding since surgery was the only significant variable in the DRS scores, with a 33-month gap predicting no regret (p = 0.02 compared to shorter gaps). The reasons for circumcision did not significantly differ between the "regret" and "no-regret" groups (p = 0.23). DISCUSSION: Our current investigation revealed a lower incidence of parental regret when compared to previous reports following distal hypospadias repair, likely attributable to the lower complication rate associated with circumcision. Our data reflect the experience of a single center in a country where neonatal male circumcision is routinely performed for cultural and religious reasons, thus precluding the generalization of our findings to places where post-natal circumcision is less commonplace. CONCLUSION: Consent to their son's post-neonatal circumcision was regretted by 13.8% of parents. Time since surgery significantly influenced the reduction of their negative attitudes.

MRI-based PI-RADS score predicts ISUP upgrading and adverse pathology at radical prostatectomy in men with biopsy ISUP 1 prostate cancer.

INTRODUCTION: Most men diagnosed with very-low and low-risk prostate cancer are candidates for active surveillance; however, there is still a misclassification risk. We examined whether PI-RADS category 4 or 5 combined with ISUP 1 on prostate biopsy predicts upgrading and/or adverse pathology at radical prostatectomy. MATERIALS AND METHODS: A total of 127 patients had ISUP 1 cancer on biopsy after multiparametric MRI (mpMRI) and then underwent radical prostatectomy. We then evaluated them for ISUP upgrading and/or adverse pathology on radical prostatectomy. RESULTS: Eight-nine patients (70%) were diagnosed with PI-RADS 4 or 5 lesions. ISUP upgrading was significantly higher among patients with PI-RADS 4-5 lesions (84%) compared to patients with equivocal or non-suspicious mpMRI findings (26%, p < 0.001). Both PI-RADS 4-5 lesions (OR 24.3, 95% CI 7.3, 80.5, p < 0.001) and stage T2 on DRE (OR 5.9, 95% CI 1.2, 29.4, p = 0.03) were independent predictors of upgrading on multivariate logistic regression analysis. Men with PI-RADS 4-5 lesions also had significantly more extra-prostatic extension (51% vs. 3%, p < 0.001) and positive surgical margins (16% vs. 3%. p = 0.03). The only independent predictor of adverse pathology was PI-RADS 4-5 (OR 21.7, 95% CI 4.8, 99, p < 0.001). CONCLUSION: PI-RADS 4 or 5 lesions on mpMRI were strong independent predictors of upgrading and adverse pathology. Incorporating mpMRI findings when selecting patients for active surveillance must be further evaluated in future studies.

Increased prevalence of non-E. coli bacteria-caused urinary infection in neonates delivered by cesarian section.

OBJECTIVES: to assess the association between delivery mode and causative pathogens of infants with urinary tract infections. MATERIALS AND METHODS: We conducted a retrospective analysis of the medical records of neonates delivered in a tertiary academic pediatric hospital and diagnosed with urinary tract infections between January 1,2013 and December 31,2017. Excluded were newborns with urinary tract infections post-urological procedures or neurogenic bladders. The retrieved data included demographic characteristics, clinical presentations, laboratory findings, urine cultures, and renal imaging results. Multivariable logistic regressions were employed to identify associations. RESULTS: 95 of the 131 neonates' (72.5%) cultures were positive for Escherichia coli. Neonates born via cesarean section (C/S) had a significantly higher prevalence (12/25, 48%) of non-Escherichia coli infections (p = 0.01). The mode of delivery was the only variable associated with non-Escherichia coli infections (odds ratio = 3.1, p = 0.014). Two of the 12 neonates (17%) with non-Escherichia coli cultures in the C/S group were diagnosed as having dilating vesicoureteral reflux. DISCUSSION: While the impact of mode of delivery on microbiome composition and UTI risk in the pediatric population is well documented, to the best of our knowledge, our study is the first to evaluate and report on the clinical connection between mode of delivery and neonatal UTIs. Most noteworthy was our finding of an elevated prevalence of non-E. coli cultures in the C/S group (p = 0.014, OR 3.1). This bears important clinical implications, particularly in the setting of congenital anomaly of kidney and urinary tract (CAKUT) screening. CONCLUSIONS: Our analyses in this study reveal a significant link between delivery by cesarean section and neonatal urinary tract infections with non- Escherichia coli urine cultures. These findings carry implications for vesicoureteral reflux screening in neonates by raising the level of awareness of the association between the 2 factors. Additional prospective studies on larger cohorts are warranted to further elucidate this relationship and refine clinical decision-making in neonatal care.

Optimizing Colon Identification by Window Setting Modulation on Noncontrast Computed Tomography Prior to Percutaneous Nephrolithotomy.

Background: Preoperative identification of the bowel on imaging is essential in planning renal access during percutaneous nephrolithotomy (PCNL) and avoiding colonic injury. We aimed this study to assess which noncontrast computed tomography (NCCT) window setting provides the optimal colonic identification for PCNL preoperative planning. Methods: Ten urologic surgeons (four seniors, six residents) reviewed 22 images of NCCT scans in both abdomen and lung window settings in a randomized blinded order. Colonic area delineation in each image was performed using a dedicated, commercially available area calculator software. A comparison of the marked colonic area between the abdomen and lung window settings was performed. Results: Overall, the mean marked colonic area was greater in the lung window compared with the abdomen window (8.82 cm2 vs 7.4 cm2, respectively, p < 0.001). Switching the CT window from abdomen to lung increased the identified colonic area in 50 cases (50%). Intraclass correlation showed good agreement between the senior readers and among all readers (0.92 and 0.87, respectively). Similar measurements of the colonic area in both abdomen and lung windows were observed in 26/44 (60%) of the seniors cases and in 7/66 (10%) of the resident cases (p = 0.002). Conclusion: Lung window solely or in combination with abdomen window appears to provide the most accurate colonic identification for preoperative planning of PCNL access and potentially reduce the risk of colonic injury. This pattern is more evident among young urologists, and we propose to introduce it as a standard sequence in PCNL preplanning.

A combined MRI-PSAD risk stratification system for prioritizing prostate biopsies.

INTRODUCTION:   Prostate cancer screening with PSA is associated with low specificity; furthermore, little is known about the optimal timing of biopsy.  We aimed to evaluate whether a risk classification system combining PSA density (PSAD) and mpMRI can predict clinically significant cancer and determine biopsy timing. MATERIALS AND METHODS:  We reviewed the medical records of 256 men with a PI-RADS ≥ 3 lesion on mpMRI who underwent transperineal targeted and systematic biopsies of the prostate between 2017-2019.  Patients were stratified into three risk groups based on PSAD and mpMRI findings. The study endpoint was clinically significant prostate cancer (CSPC).  The association between the risk groups and CSPC was evaluated. RESULTS:  Based on the proposed risk stratification system 42/256 men (16%) were high-risk (mpMRI finding of extra-prostatic extension and/or seminal vesicle invasion and/or a PI-RADS 5 lesion with a PSAD > 0.15 ng/mL²), 164/256 (64%) intermediate-risk (PI-RADS 4-5 lesions and/or PSAD > 0.15ng/mL² with no high-risk features) and 50/256 (20%) low-risk (PI-RADS 3 lesions and PSAD ≤ 0.15 ng/mL²).  High-risk patients had significantly higher rates of CSPC (76%) when compared to intermediate-risk (26%) and low-risk (4%).  On multivariable logistic regression analysis adjusted for age, previous biopsy, and clinical T-stage we found an association between intermediate-risk (OR = 4.84, p = 0.038) and high-risk (OR = 40.13, p < 0.001) features and CSPC.  High-risk patients had a shorter median biopsy delay time (110 days) compared to intermediate- and low-risk patients (141 and 147 days, respectively).  We did not find an association between biopsy delay and CSPC. CONCLUSIONS:   Our findings suggest that a three-tier risk classification system based on mpMRI and PSAD can identify patients at high-risk for CSPC who may benefit from earlier biopsy.

Use of Validated Questionnaires to Predict Cosmetic Outcomes of Hypospadias Repair.

INTRODUCTION: Hypospadias is a syndrome of penile maldevelopment. The primary goal of hypospadias surgery is to create a penis with normal appearance and function. Historically, the outcome of hypospadias repair has been assessed based on the need for reoperation due to urethroplasty complications (UC), including fistula formation, dehiscence, meatal stenosis, or development of a urethral stricture. The Glans-Urethral Meatus-Shaft (GMS) score is a standardized tool to predict UC. Analysis of the cosmetic outcomes of hypospadias repair based on the appearance of the reconstructed penis has been validated, and standardized scores have been published. The Hypospadias Objective Penile Evaluation (HOPE) score is a validated questionnaire used to assess postoperative cosmetic outcomes. Although predictors of surgical outcomes and UC have been well documented, predictors of optimal cosmetic outcomes are lacking in the literature. Furthermore, reoperation due to cosmetic considerations has been poorly reported. OBJECTIVE: To identify predictors of cosmetic outcomes after hypospadias repair and to assess the reoperation rate according to cosmetic considerations. MATERIALS AND METHODS: This prospective cohort study included 126 boys who underwent primary hypospadias repair. The severity of hypospadias, degree of penile curvature, glans width, preoperative HOPE, and GMS scores were documented. The standard technique for single-stage repairs, the tubularized incised plate urethroplasty, was performed. The primary endpoint was cosmetic outcomes evaluated by the HOPE score questionnaire six months postoperatively. Optimal cosmetic results were defined by HOPE scores ≥ 57. RESULTS: The study population consisted of the following cases: 87 (69%) subcoronal, 32 (25%) shaft, and 7 (6%) proximal hypospadias. Among the study participants, 102 boys (81%) had optimal cosmetic results (HOPE ≥ 57), and 24 boys (19%) had surgeries with suboptimal cosmetic outcomes (HOPE < 57). Ancillary procedures were performed in 21 boys (16%), of which 14 (11%) were solely for cosmetic considerations, and 7 were secondary to UC. Using the Receiver Operating Characteristic analysis of potential predictors of optimal cosmetic outcomes, the preoperative HOPE score had the highest area under the curve (AUC = 0.79; 95% CI 0.69-0.89, p < 0.001). After multivariable analysis, the degree of penile chordee (p = 0.013), glans width (p = 0.003), GMS score (p = 0.007), and preoperative HOPE score (p = 0.002) were significant predictors of cosmetic outcomes. Although meatal location predicted suboptimal cosmetic results in univariate analysis, it was not a factor in multivariable analysis. CONCLUSIONS: Over 80% of boys undergoing hypospadias repair achieved optimal cosmetic outcomes. More than 10% of cases underwent ancillary procedures, secondary solely to cosmetic considerations. Predictors of optimal cosmetic outcomes after hypospadias surgery included degree of chordee, glans width, and preoperative HOPE and GMS scores, which were the best predictors of satisfactory cosmetic results. Although meatal location is the main predictor of UC, it was not a predictor for cosmetic outcomes. Factors affecting cosmetic outcomes should be clearly explained to parents during the preoperative consultation.

Megameatus intact prepuce variant reconstruction: Long-term outcomes and comparison to post-circumcision hypospadias repair.

BACKGROUND: Megameatus intact prepuce (MIP) variant is considered a surgical challenge with associated high complication rates. It is usually diagnosed and corrected only after neonatal circumcision, which is discouraged in non-MIP hypospadias. OBJECTIVE: In order to determine whether the features of the MIP variant or the performance of a secondary reconstruction following circumcision comprise the cause of higher complication rates, we now compared the results of post-circumcision MIP hypospadias repair to the results of children who underwent repair of non-MIP hypospadias following neonatal circumcision. STUDY DESIGN: Reoperation rates of children operated for hypospadias repair following neonatal circumcision between 1999 and 2020 were compared between those with MIP and those with classic non-MIP hypospadias. RESULTS: In total, 139 patients who had undergone neonatal circumcision underwent surgical reconstruction at a mean age of 13 months. Sixty-nine had classic hypospadias and 70 had the MIP variant. The median follow-up was 10 years (interquartile range 6,13). The classic group had a higher rate of meatal location below the corona compared to the MIP variant group (53 % vs. 28 %, respectively, p = 0.002). The reoperation rate was comparable for the two groups (32 % vs. 27 %, p = 0.58, Table). Univariate analysis for the MIP hypospadias group showed no association between reoperation and the initial patient characteristics, while a higher probability of reoperation was demonstrated in the presence of ventral curvature (odds ratio 3.5, p = 0.02), and a higher grade of hypospadias (odds ratio 3.3, p = 0.03 for meatal location lower than the coronal sulcus) in the non-MIP group. DISCUSSION: The limitations of our work include its retrospective design wherein the patients' characteristics, including classification as MIP vs. non-MIP, are derived from medical records. More patients in the non-MIP group were documented to have penile curvature. The non-MIP group was composed of more patients with meatal location under the coronal sulcus, a factor which may increase the rates for reoperation in that group. Still, with the comparison of the largest reported cohort of circumcised MIP with circumcised non-MIP patients together with an extended follow-up period, we believe that we present strong evidence of the possible role of previous circumcision in the surgical challenge of reconstructing MIP hypospadias. CONCLUSIONS: Reoperation rates in MIP hypospadias are high but similar to those of classic hypospadias, both following circumcision, suggesting that circumcision, rather than the unique features of the variant, is the cause for complications.

Mini-HoLEP (MILEP) vs HoLEP: a propensity score-matched analysis.

BACKGROUND AND PURPOSE: Minimal invasiveness improves outcome in many surgical fields including urology. We aimed to assess intraoperative performance and clinical outcome of miniaturized holmium laser enucleation of prostate (MiLEP) (22FR). METHODS: We ran a propensity score-matched analysis among all consecutive laser enucleations of prostate performed between 9/2022 and 2/2023. It resulted in two matched comparison groups: MiLEP 22 FR (n = 40) and holmium laser enucleation of prostate (HoLEP 26 Fr) (n = 40). Statistical analysis was performed. RESULTS: MiLEP was associated with significantly less intraoperative irrigation (20.5 L vs 15 L, p = 0.002E-3), less decrease in body core temperature (0.6°C vs 0.1°C, p = 0.003E-5), and less need for meatal dilation (25% vs 78%, p = 0.01E-3). These parameters were identified as being independent in the multivariate analysis. There was a trend toward less and a shorter period of postoperative stress incontinence (SI) for the MiLEP group compared to the HoLEP group: 15% and 42% (p = 0.01) at 1 month, 8% and 14% (p = 0.07) at 2 months, and 0 and 0.3% (p = 1) at 3 months, respectively. There were no differences in prostatic enucleation effectiveness, operative time, hospital stay, complications, and improvement in the international prostate symptom score and quality of life score. CONCLUSIONS: MiLEP is feasible and provides better maintenance of body core temperature, reduction in amount of fluid irrigation, and decrease in need for meatal dilation without affecting effectiveness in comparison with HoLEP. MiLEP may reduce early postoperative stress incontinence, thereby shortening the recovery period.

Complete Blood Count Markers and C-Reactive Protein as Predictors of Testicular Viability in the Event of Testicular Torsion in Adults.

INTRODUCTION: The association between blood markers and testicular viability after testicular torsion (TT) is not well known. We evaluated the role of complete blood count markers and C-reactive protein (CRP) in predicting testicular viability after TT. METHODS: Fifty men, ≥18 years of age, operated for TT between the years 2015-2020 were enrolled. Blood markers including neutrophil-, lymphocyte-, and platelet count, and CRP were obtained. Neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) were calculated. The study outcome was testicular salvage. RESULTS: Median age was 23 years (interquartile range [IQR]: 21, 31). Median duration of torsion was 10 h (IQR: 6, 42). Sonographic texture of the testis was homogenous in 27 (56%) patients and heterogenous in 21 (44%). During scrotal exploration, 36 patients (72%) underwent orchiopexy and 14 (28%) underwent orchiectomy. Patients who underwent orchiopexy were younger (22 years vs. 31 years, p = 0.009), had a shorter duration of torsion (median 8 h vs. 48 h, p < 0.001), and a homogenous texture on scrotal ultrasound (76.5 vs. 7.1%, p < 0.001). Median NLR, PLR, and CRP were higher among patients who underwent orchiectomy; however, these differences did not reach statistical significance. Patients with heterogenous echotexture were significantly more likely to undergo orchiectomy (odds ratio = 42, 95% confidence interval: 7, 831, adjusted p value = 0.009). CONCLUSIONS: We found no association between blood-based biomarkers and testicular viability after TT; however, testicular echotexture significantly predicted outcome.

The role of tumor density in predicting significant cancer on targeted biopsy of the prostate.

OBJECTIVE: Multiparametric magnetic resonance imaging (mpMRI) is central to diagnosing prostate cancer; however, not all imaged lesions represent clinically significant tumors. We aimed to evaluate the association between the relative tumor volume on mpMRI and clinically significant prostate cancer on biopsy. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 340 patients who underwent combined transperineal targeted and systematic prostate biopsies between 2017 and 2021. Tumor volume was estimated based on the mpMRI diameter of suspected lesions. Relative tumor volume (tumor density) was calculated by dividing the tumor and prostate volumes. The study outcome was clinically significant cancer on biopsy. Logistic regression analyses were used to evaluate the association between tumor density and the outcome. The cutoff for tumor density was determined with ROC curves. RESULTS: Median estimated prostate and peripheral zone tumor volumes were 55cm3 and 0.61cm3, respectively. Median PSA density was 0.13 and peripheral zone tumor density was 0.01. Overall, 231 patients (68%) had any cancer and 130 (38%) had clinically significant cancer. On multivariable logistic regression age, PSA, previous biopsy, maximal PI-RADS score, prostate volume, and peripheral zone tumor density were significant predictors of outcome. Using a threshold of 0.006, the sensitivity, specificity, positive and negative predictive values of peripheral zone tumor density were 0.9, 0.51, 0.57, and 0.88, respectively. CONCLUSION: Peripheral zone tumor density is associated with clinically significant prostate cancer in patients with PI-RADS 4 and 5 mpMRI lesions. Future studies are required to validate our findings and evaluate the role of tumor density in avoiding unnecessary biopsies.

Periprocedural antibiotics for urodynamic studies of pediatric neurogenic bladder, empiric or culture-guided? A retrospective cohort study.

INTRODUCTION: Urodynamic studies are fundamental in the care of children with neurogenic bladder. Children with neurogenic bladder who perform clean intermittent catheterization (CIC) are considered a high-risk group for infection after urodynamic studies. Current guidelines are not uniform regarding the duration, type, the need of prophylactic antibiotic treatment or performance of urine culture before urodynamic studies. OBJECTIVE: To assess whether antibiotic prophylactic therapy before urodynamic studies should be empiric or culture-guided in children with neurogenic bladder who perform CIC. STUDY DESIGN: Urine samples were collected from children with neurogenic bladder who require CIC before undergoing a urodynamic study. Urine cultures were collected via sterile urethral catheterization one week before urodynamic studies between 2010 and 2018. Children with signs of urinary tract infection (UTI) or children with bladder augmentation were excluded. Resistance to commonly prescribed periprocedural antibiotic treatments was documented. The probability of antibiotic resistance according to sex, vesicoureteral reflux (VUR) status, consumption of prophylactic antibiotics, and self/caregiver performed CIC was determined by a χ2-test. RESULTS: A total of 278 urine cultures were collected from 185 children with neurogenic bladder. The median age was 8 years (IQR 5-12). The most common etiology for neurogenic bladder was spinal dysraphism (n = 146, 77%). Bacterial growth was detected in 216 (78%) cultures, and the most commonly detected bacterial species was Escherichia. coli (n = 155, 72%). Thirty-six (19%) children had VUR, and 14 of them received continuous prophylactic antibiotics. The probability of resistance to oral antibiotics was amoxicillin (22%), cephalexin (21%), cefuroxime (14%), ciprofloxacin (10%), nitrofurantoin (21%), and sulfamethoxazole/trimethoprim (SMX/TMP) (23%) (See "summary table") No significant differences were found by χ2-test in the probability of resistance to antibiotics according to sex, VUR status, continuous antibiotic prophylaxis or self/caregiver performed CIC. DISCUSSION: The study reveals high resistance level to commonly prescribed oral antibiotic treatments (20-30%). Several studies have challenged the need of routine urine cultures before urodynamic studies due to low risk of post-procedural infection. However, it should be mentioned that not all the patients participating in those studies were with neurogenic bladder or routinely performed CIC. Hence, in this specific group of children, routine urine cultures should not be abandoned. The limitations of the study are: Single-center, retrospective study with no data availability regarding the development of UTI after the urodynamic studies. CONCLUSIONS: Urine cultures of children with neurogenic bladder who require CIC demonstrate significant levels of resistance to commonly prescribed oral antibiotics. These findings support culture-guided periprocedural antibiotic prophylaxis.

The role of serum and urinary markers in predicting obstructing ureteral stones and reducing unjustified non-contrast computerized tomographic scans in emergency departments.

INTRODUCTION: The reported yield of non-contrast computed tomography (NCCT) in assessing flank pain and obstructive urolithiasis (OU) in emergency departments (EDs) is only ~ 50%. We investigated the potential capability of serum and urinary markers to predict OU and improve the yield of NCCT in EDs. METHODS: All consecutive ED patients with acute flank pain suggestive of OU and assessed by NCCT between December 2019 and February 2020 were enrolled. Serum white blood cells (WBC), C-reactive protein (CRP) and creatinine (Cr) levels, and urine dipstick results were analyzed for association with OU, and unjustified NCCT scan rates were calculated. RESULTS: NCCTs diagnosed OU in 108 of the 200 study patients (54%). The median WBC, CRP, and Cr values were 9,100/µL, 4.3 mg/L, and 1 mg/dL, respectively. Using ROC curves, WBC = 10,000/µL and Cr = 0.95 mg/dl were the most accurate thresholds to predict OU. Only WBC ≥ 10,000/µL (OR = 3.7, 95% CI 1.6-8.3, p = 0.002) and Cr ≥ 0.95 mg/dl (OR = 5, 95% CI 2.3-11, p < 0.001) were associated with OU. Positive predictive value and specificity for detecting OU among patients with combined WBC ≥ 10,000 and Cr ≥ 0.95 were 83% and 89%, respectively. Patients negative to the serum markers criteria underwent significantly more unjustified NCCTs (p = 0.03). The negative predictive value of the serum criteria for justified NCCT scanning was 81%. CONCLUSIONS: WBC and Cr may be valuable serum markers in predicting OU among patients presenting to EDs with acute flank pain. They may potentially reduce the number of unjustified NCCT scans in the ED setting.

External validation of a simplified prognostic model for survival in patients with extrinsic malignant ureteral obstruction treated with tandem ureteral stents - a retrospective cohort study.

INTRODUCTION: Prognostic models of survival can identify patients with extrinsic malignant ureteral obstruction who will benefit from long-term drainage as offered by tandem ureteral stents. The study aims to validate a simplified prognostic model published by Cordeiro et al. and to identify additional prognostic predictors in a cohort of patients drained solely with tandem ureteral stents. METHODS: Medical records of consecutive patients who underwent drainage of malignant ureteral obstruction with tandem ureteral stents between 2007 and 2020 were reviewed retrospectively; patients with benign ureteral obstruction were excluded. Risk factors for survival included were: [1] the number of malignancy-related events (categorized as ≥4 and <4) and [2] the Eastern Cooperative Oncology Group Index (categorized as ≥2 and <2)]. Patients with ≥1 risk factor were grouped as intermediate-unfavorable risk and those without risk factors as favorable risk. The Kaplan-Meier and log-rank tests were used for survival analysis. Univariable and multivariable Cox regression analyses were used to identify predictors of outcome. RESULTS: The study cohort consisted of 65 patients; the median age was 60 years (IQR 51-72). The median follow-up time from diagnosis of hydronephrosis was 51 months (IQR 38-64). Estimated probabilities of survival at 1 month, 6 months 1 year, and 2 years were 100%, 87%, 75% and 57%, respectively in the favorable risk group (n = 40), and in the intermediate-unfavorable risk group (n = 25), 96%, 72%, 52%, and 20%, respectively, (p = .003). On multivariable analysis, the presence of ≥4 malignancy-related events (HR = 2.04, 95% CI [1.07-3.86], p = .03) and lung metastasis (HR = 2.37, 95% CI [1.0-5.6], p = .05) were associated with shorter survival. CONCLUSIONS: Our findings validate the prognostic model published by Cordeiro et al. The model can be applied when counseling patients being considered for drainage with tandem ureteral stents.

Preoperative Bladder Capacity Predicts Social Continence following Bladder Neck Reconstruction in Children Born with Exstrophy-Epispadias Complex.

INTRODUCTION: The aim of the study is to review the continence and volitional voiding rate in a single center cohort of exstrophy-epispadias patients following Young-Dees-Leadbetter bladder neck reconstruction and to explore factors which predict continence. MATERIALS AND METHODS: Children who underwent Young-Dees-Leadbetter bladder neck reconstruction as a final stage of repair in a large single low-volume center in a small-population country between 1997 and 2019 were included. Demographic and clinical details were extracted from the patients' charts. The primary end point was continence and volitional voiding. Patients were categorized as incontinent, socially continent (daytime dry intervals > 3 hours, wet nights) and fully continent (daytime dry intervals > 3 hours, dry nights). RESULTS: The study cohort included 27 patients whose median age at reconstruction was 5 years, and median follow-up was 7.8 years (interquartile range [IQR] 6-11.2). The cohort included 24 classic exstrophy patients (89%, 17 males and 7 females) and 3 isolated complete epispadias patients (11%, 1 male and 2 females). Nine (33%) patients achieved full continence and social continence was achieved by nine (33%) patients, for an overall social continence rate of 67%. Preoperative bladder capacity of 110 mL or more was associated with achieving social continence (odds ratio = 6.4, p = 0.047). The overall volitional voiding rate was 67%. CONCLUSION: Young-Dees-Leadbetter bladder neck reconstruction yielded rates of 33% for full continence and 67% for social continence and volitional voiding. These rates are comparable to those of large high-volume centers. A preoperative capacity of 110 mL or more was the sole predictor of social continence.

Improving Prostatic Preoperative Volume Estimation and Planning before Laser Enucleation.

We aimed to validate a formula for improving the estimation of prostatic volume by abdominal ultrasound (AUS) prior to transurethral laser enucleation. A total of 293 patients treated for benign prostate hyperplasia (BPH) by laser enucleation from 2019−2022 were included. The preoperative AUS volume was adjusted by the formula 1.082 × Age + 0.523 × AUS − 53.845, which was based on specimens retrieved by suprapubic prostatectomy. The results were compared to the weight of the tissue removed by laser enucleation as determined by the intraclass correlation coefficient test (ICC). The potential impact of preoperative planning on operating time was calculated. The ICC between the adjusted volumes and the enucleated tissue weights was 0.86 (p < 0.001). The adjusted volume was more accurate than the AUS volume (weight-to-volume ratio of 0.84 vs. 0.7, p < 0.001) and even more precise for prostates weighing >80 g. The median operating time was 90 min. The adjusted volume estimation resulted in an overall shorter expected preoperative operating time by a median of 21 min (24%) and by a median of 40 min in prostates weighing >80 g. The adjustment formula accurately predicts prostate volume before laser enucleation procedures and may significantly improve preoperative planning, the matching of a surgeon's level of expertise, and the management of patients' expectations.

Postoperative Urinary Catheterization in Children Treated with or without Epidural Analgesia after Orthopedic Surgery: A Retrospective Review of Practice.

Epidural analgesia is effective and an accepted treatment for postoperative pain. Urinary retention is a known complication, but its description is mostly in the adult literature. Management of urinary catheter (UC) placement and removal is an important consideration in children receiving epidural analgesia. This is a single-center, retrospective observational study which examined UC management in children undergoing lower extremity orthopedic surgery under general anesthesia with or without epidural analgesia from January 2019−June 2021. Of 239 children included, epidural analgesia was used in 57 (23.8%). They were significantly younger and had more co-morbidities. In total, 75 UCs were placed in the OR, 9 in the ward, and 7 re-inserted. UC placement in the epidural group was more common (93% vs. 17%, p < 0.001) and remained longer (3 days vs. 1 day, p = 0.01). Among children without intra-operative UC, ward placement was more common in the epidural cohort (60% vs. 1.6%, p = 0.007). OR UC placement and ward re-insertion were more common in children with neuromuscular disease (61% vs. 22%, p < 0.001), (17% vs. 3%, p = 0.001), respectively. Based on these findings, we hypothesize that it is justifiable to routinely place a UC intra-operatively in children who undergo hip or lower extremity surgery and are treated with epidural analgesia, and caution is advised before early UC removal in orthopedic children with NMD.

Operative techniques and long-term outcomes of hypospadias repair in the absence of preputial skin after neonatal circumcision.

PURPOSE: To present the results of hypospadias repair in the absence of preputial skin following neonatal circumcision, and the analyses of surgical techniques and predictors of procedural success. METHODS: Records of all children who underwent hypospadias repair between 10/1999 and 12/2018 were retrospectively reviewed. All of those who underwent neonatal circumcision prior to surgery were included. Patients with any prior penile reconstruction surgery and those with the megameatus intact prepuce variant were excluded. The primary endpoint was the need for reoperation. RESULTS: A total of 69 patients with a history of neonatal circumcision underwent surgical reconstruction of hypospadias during the study period. Their mean age at surgery was 14 months (interquartile range [IQR] 9,22). Forty-five cases (65%) involved distal hypospadias, and ventral curvature was present in 24 (35%). Dartos flaps were harvested from the dorsal aspect in 37/58 (64%) patients and from the ventral aspect in 21/58 (36%). Twenty-two patients (22/69, 32%) required reoperation after a median follow-up of 9 years (IQR 6,13). Indications for revision surgery included urethral fistula (n = 16, 22%), meatal stenosis (n = 5, 7%), and skin redundancy (n = 1). Ventral curvature (odds ratio [OR] 3.5, p = 0.02) and higher grades of hypospadias. (OR 3.3, p = 0.03) had a higher probability of reoperation (univariate logistic regression). CONCLUSION: Hypospadias repair following neonatal circumcision in the absence of preputial skin is a challenging reconstruction. The reoperation rate in our cohort was 30%, similar to reoperative hypospadias surgery. Parents of newborns diagnosed with hypospadias should be encouraged to refrain from pre surgical neonatal circumcision. LEVEL OF EVIDENCE: Treatment study, level IV.

68Ga-prostate-specific membrane antigen positron emission tomography/computed tomography for patients with favorable intermediate-risk prostate cancer.

INTRODUCTION: Current guidelines do not support the use of pretreatment imaging in patients with favorable intermediate-risk prostate cancer. 68Ga-prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) is more accurate than conventional imaging for preoperative staging. We aimed to evaluate whether pretreatment 68Ga-PSMA PET/CT is beneficial for identifying pathological lymph node involvement (LNI) and adverse pathology among patients with favorable intermediate-risk prostate cancer. METHODS: We reviewed 88 patients with favorable intermediate-risk prostate cancer who underwent 68Ga-PSMA PET/CT prior to radical prostatectomy and lymph node dissection from 2016-2020. The primary endpoint was the presence of pathological LNI. Association between pretreatment characteristics and outcomes were evaluated. RESULTS: Preoperative 68Ga-PSMA PET/CT showed suspicious uptake in lymph nodes in 4/88 patients (5%), hence, 20 patients would need to be scanned to identify a patient with a positive lymph node on imaging. Two patients had pathological LNI, only one of whom showed 68Ga-PSMA PET/CT uptake prior to surgery. The sensitivity, specificity, positive predictive value, and negative predictive values of 68Ga-PSMA PET/CT for identifying LNI were 50%, 97%, 25%, and 99%, respectively. After surgery, four patients had evidence of prostate-specific antigen (PSA) persistence. The rate of PSA persistence was higher among patients with LNI on preoperative 68Ga-PSMA PET/CT (2/4, 50% vs. 2/84, 2%, p=0.009). CONCLUSIONS: Preoperative imaging of favorable intermediate-risk prostate cancer patients using 68Ga-PSMA PET/CT showed a low yield for identifying patients at higher risk. Consistent with current guidelines, our findings do not support the routine use of PET/CT in this group of patients. Future prospective studies are needed to validate our findings.

Parental Regret Following Decision to Revise Circumcision.

Purpose: Revision surgery for the removal of excess foreskin after circumcision is a common procedure. The decision regret scale (DRS) is a validated questionnaire which assesses regret after medical decision making. The aim was to evaluate parental regret by means of the DRS and querying about factors associated with regret about deciding to revise their child's circumcision. Patients and Methods: Included were all pediatric patients who underwent revision of neonatal circumcision in a single center between 2010 and 2016. Excluded were children who underwent revision for reasons other than excess foreskin, those who underwent additional surgical procedures during the same anesthetic session, and those who had undergone previous penile surgery other than circumcision. Response to the DRS questionnaire was by a telephone call with the patient's parent. Regret was classified as none (a score of 0), mild (1-25), or moderate-to-strong (26-100). Surgical and baseline demographic data were obtained from the departmental database and compared between the no regret and regret groups. Results: Of the 115 revisions of circumcisions performed during the study period, 52 fulfilled the inclusion criteria, and the parents of 40 (77%) completed the DRS questionnaire. Regret was reported by 11/40 [28%: nine as mild (23%) and two as moderate-to-strong (5%)]. The average age of the child in the regret group was 17 months compared to 18 months in the no regret group (p = 0.27). The median weight percentile was 43% in both groups. Surgical variables, including anesthesia type (caudal vs. no block, p = 0.65), suture type (polyglactin vs. poliglecaprone, p = 0.29), operation time (28 vs. 25 min, p = 0.59), and anesthesia time (55 vs. 54 min, p = 0.57) were not significantly different between the groups. Conclusions: Regret for deciding upon revision surgery for removal of excess foreskin post-circumcision was reported by 27.5% of parents of children who underwent revision. No clinical, surgical, or demographic characteristics predicted parental decisional regret.

Concomitant Repair of Meatal Stenosis and Urethral Fistula Does Not Increase the Risk of Fistula Recurrence Post Hypospadias Surgery.

OBJECTIVE: To evaluate whether meatal stenosis treated concomitantly with urethral fistula repair alters the results of fistula closure. METHODS: A retrospective cohort study, included were all children who underwent local fistula closure following hypospadias repair between 2006 and 2017. Patients who underwent reoperative urethroplasty were excluded. Data were extracted from electronic records, and missing data were supplied by telephone interviews. Characteristics of patients and fistulas were compared between children who underwent fistula closure only and those who underwent meatoplasty for meatal stenosis during the same surgery. The primary endpoint was fistula recurrence. RESULTS: In total, 106 local repairs of urethrocutaneous fistulas were performed during the study period, and 25 of them included concomitant meatoplasty for meatal stenosis. There was no difference in terms of location, size, and number of fistulas or the number of recurrent fistulas between the 81 patients who underwent fistula closure only and the 25 who underwent concomitant meatoplasty. The fistula recurrence rate was 17 per 81 (21%) for the fistula only group and 5 per 25 (20%) for the fistula and meatoplasty group after a median follow-up of 7 and 8 years, respectively. Meatoplasty was required in a subsequent procedure in 5 of 81 in the former group vs 3 of 25 patients in the latter group. CONCLUSION: The presence and repair of meatal stenosis does not alter the recurrence rate of urethrocutaneous fistulas repaired concomitantly following hypospadias repair.
