RESUMO
Anticipating and addressing unexpected intraoperative events and anatomies are some of the most challenging aspects of pediatric urologic practice; uncontrolled hemorrhage is one of the most anxiety provoking and precarious. The increasing application of the robotic platform in pediatric urology adds another layer of complexity as surgeons are not immediately at the patient's bedside. Should hemorrhage occur in robotic cases, clear communication and seamless coordination between members of the operating room team are paramount to optimize patient safety and minimize errors. This is especially important in pediatric cases for which the margin of error is narrow. Non-technical skills, including leadership, decision-making, situational awareness, stress management, and team-communication, become increasingly critical. While many programs have focused on robotic training, few prepare the operating room team and surgical trainees to manage these unforeseen, emergent intraoperative scenarios. This review discusses the role of a multidisciplinary, in situ robot-to-open conversion simulation program in addressing this educational gap, ways to approach establishing these programs, and potential barriers.

PURPOSE: This study aimed to analyze organ system-based causes and non-organ system-based mechanisms of death (COD, MOD) in people with myelomeningocele (MMC), comparing urological to other COD. METHODS: A retrospective review was performed of 16 institutions in Canada/United States of non-random convenience sample of people with MMC (born > = 1972) using non-parametric statistics. RESULTS: Of 293 deaths (89% shunted hydrocephalus), 12% occurred in infancy, 35% in childhood, and 53% in adulthood (documented COD: 74%). For 261 shunted individuals, leading COD were neurological (21%) and pulmonary (17%), and leading MOD were infections (34%, including shunt infections: 4%) and non-infectious shunt malfunctions (14%). For 32 unshunted individuals, leading COD were pulmonary (34%) and cardiovascular (13%), and leading MOD were infections (38%) and non-infectious pulmonary (16%). COD and MOD varied by shunt status and age (p < = 0.04), not ambulation or birthyear (p > = 0.16). Urology-related deaths (urosepsis, renal failure, hematuria, bladder perforation/cancer: 10%) were more likely in females (p = 0.01), independent of age, shunt, or ambulatory status (p > = 0.40). COD/MOD were independent of bladder augmentation (p = >0.11). Unexplained deaths while asleep (4%) were independent of age, shunt status, and epilepsy (p >= 0.47). CONCLUSION: COD varied by shunt status. Leading MOD were infectious. Urology-related deaths (10%) were independent of shunt status; 26% of COD were unknown. Life-long multidisciplinary care and accurate mortality documentation are needed.

INTRODUCTION: Ureteral stents facilitate recovery and avoid external drains in pediatric ureteral reconstruction. Extraction strings avoid the need for a secondary cystoscopy and anesthetic. Due to concerns regarding febrile UTIs in children with extraction strings, we retrospectively assessed the relative risk of UTI in children with extraction strings. OBJECTIVE: Our hypothesis was that stents with extraction strings do not increase the risk of UTI after pediatric ureteral reconstruction. METHODS: Records of all children undergoing pyeloplasty and ureteroureterostomy (UU) from 2014 to 2021 were reviewed. The incidences of UTI, fever, and hospitalization were recorded. RESULTS: 245 patients mean age 6.4 years (163M:82F) underwent pyeloplasty (n = 221) or UU (n = 24). 42% (n = 103) received prophylaxis. Of these, 15% developed UTI versus 5% of those not receiving prophylaxis (p < 0.05). 42 females had prior history of UTI, compared to 20 males (p < 0.05). 49 patients had an extraction string. Stents with extraction strings were removed on average 0.6 months post-op while others underwent cystoscopic removal on average 1.26 months post-op (p < 0.05). 9 (18.4%) required hospitalization for febrile UTI while the stent with extraction string was in place, while only 13 (6.6%) of those without extraction string did (p < 0.02). Of the 9 children with a febrile UTI in the extraction string group, 6 had history of prior UTI (46.1%), compared to only 3 (8.3%) without a prior UTI (p < 0.05). With no prior UTI, there was no difference in UTI risk between those with (3, 8.3%) and without (8, 6.4%) extraction string (p = 0.71). Females with prior UTI and extraction string were more likely to develop UTI than those with prior UTI and no extraction string (p = 0.01). There were not enough males with history of UTI to analyze alone. There were 5 (10%) stent dislodgements in the extraction string group, 2 required further intervention with cystoscopy or percutaneous drainage. DISCUSSION: Extraction strings provide the assurance of drainage while avoiding the need for a second general anesthetic procedure. There is not an increased risk of UTI with extraction string in those without prior history of UTI, but we no longer routinely leave extraction strings if there is history of UTI. CONCLUSION: Children, particularly females, with prior history of UTI have a significantly increased risk of febrile UTIs associated with the use of extraction strings. Prophylaxis does not seem to reduce this risk. Patients with no prior UTI had no higher risk of UTI with extraction string use for pyeloplasty or UU.

INTRODUCTION: Children with an isolated fibrolipoma of filum terminale (IFFT) but otherwise normal spinal cord are often evaluated with video urodynamics (VUDS). VUDS interpretation is subjective and can be difficult in young children. These patients may undergo detethering surgery if there is concern for current or future symptomatic tethered cord. OBJECTIVE: We hypothesized that VUDS in children with IFFT would have limited clinical utility regarding decision for or against detethering surgery and VUDS interpretation would have poor interrater reliability. METHODS: Patients with IFFT who underwent VUDS for from 2009 to 2021 were retrospectively reviewed to evaluate clinical utility of VUDS. 6 pediatric urologists who were blinded to patient clinical characteristics reviewed the VUDS. Gwet's first order agreement coefficient (AC1) with 95% CI was used to assess interrater reliability. RESULTS: 47 patients (24F:23M) were identified. Median age at initial evaluation was 2.8yrs (IQR:1.5-6.8). 24 (51%) patients underwent detethering surgery (Table). VUDS at initial evaluation were interpreted by treating urologist as normal in 4 (8%), reassuring for normal in 39 (81%), or concerning for abnormal in 4 (9%). Based on neurosurgery clinic and operative notes for the 47 patients, VUDS made no change in management in 37 patients (79%), prompted detethering in 3 (6%), was given as reason for observation in 7 (15%), and was normal or reassuring for normal but not documented as a reason for observation in 16 (34%) (Table). Interrater reliability for VUDS interpretation had fair agreement (AC1 = 0.27) for overall categorization of VUDS and EMG interpretation (AC1 = 0.34). Moderate agreement was seen for detrusor overactivity interpretation (AC1 = 0.54) and bladder neck appearance (AC1 = 0.46). DISCUSSION: In our cohort, 90% of patients had a normal or reassuring for normal interpretation of VUDS. VUDS interpretation affected clinical course in a minority of patients. There was fair interrater reliability for overall VUDS interpretation and therefore clinical course regarding detethering surgery could vary depending upon interpreting urologist. This fair interrater variability appeared to be related to variability in EMG, bladder neck appearance, and detrusor overactivity interpretation. CONCLUSION: VUDS affected clinical management in about 20% of our cohort and supported the choice for observation in around 50% of patients. This suggests VUDS does have clinical utility in pediatric patients with IFFT. The overall VUDS interpretation had fair interrater reliability. This suggest VUDS interpretation has limitations in determining normal versus abnormal bladder function in children with IFFT. Neurosurgeons and urologists should be aware of VUDS limitations in this patient population.

Anterior abdominal wall defects are rare anomalies that can affect multiple organ systems including gastrointestinal, genitourinary, musculoskeletal, and the neurospinal axis. The highly varied, complex anatomy in this patient population creates a challenging reconstruction scenario that merits careful surgical planning. We present an unusual female variant with an anorectal malformation as well as musculoskeletal and genital abnormalities consistent with classic bladder exstrophy in which the urinary bladder, sphincter, and urethra were largely uninvolved.

Urethrocutaneous fistula is an unfortunate but well recognized complication of hypospadias repair surgery and traumatic injury to the penis. Congenital anterior urethrocutaneous fistula of the male urethra is an exceedingly rare phenomenon, with approximately 50 cases being reported in the literature. We report a case of proximal isolated congenital anterior urethrocutaneous fistula at the penoscrotal junction.
RESUMO
BACKGROUND: Bacteremia and endocarditis caused by Staphylococcus aureus (S. aureus), particularly methicillin-resistant S. aureus (MRSA), are challenging to treat and are associated with high morbidity and mortality. Telavancin is a lipoglycopeptide antibacterial active against susceptible Gram-positive pathogens, including MRSA. OBJECTIVE: This registry study assessed the real-world use and clinical outcomes of telavancin in patients with bacteremia or endocarditis enrolled in the Telavancin Observation Use Registry (TOUR™). METHODS: The subset of patients enrolled in TOUR who were diagnosed with endocarditis and/or bacteremia with a known or unknown primary source (N = 151) were analyzed. Data including demographics, infection type, baseline pathogens, prior or concomitant antimicrobial therapy, dosing regimen, clinical response, treatment-emergent adverse events (TEAEs) of interest, and mortality were collected by retrospective medical chart review. RESULTS: Telavancin was primarily used as a second-line or greater therapy (n = 132, 87.4%). MRSA was present in 87 (57.6%) patients. Median telavancin dose was 740.6 mg (interquartile range (IQR) 206.0 mg) and median duration of therapy was 9.0 days (IQR 24.0 days). Of the 132/151 (87.4%) patients with an available assessment at the end of telavancin therapy, a positive clinical response was achieved in 98/132 (74.2%), while 14/132 (10.6%) failed therapy and 20/132 (15.2%) had an indeterminant outcome. TEAEs occurred in 24 (15.9%) patients. The most frequent TEAE was renal failure (n = 12, 7.9%); seven of these patients were receiving concomitant nephrotoxic medications. There was no change in creatinine clearance for 67/89 (75.3%) patients with values recorded at the beginning and the end of telavancin therapy. CONCLUSIONS: In real-world clinical practice, overall positive clinical outcomes are observed in patients with bacteremia or endocarditis treated with telavancin, including in those patients infected with MRSA or another S. aureus pathogen. Telavancin may be an alternative treatment option for these patients. TRIAL REGISTRATION: This trial was registered with clinicaltrials.gov (NCT02288234) on 11 November 2014.
RESUMO
Splenogonadal fusion remains a rare congenital anomaly, with limited reports in the literature. It is important to be aware of this benign condition as orchiectomy can result from confusion with malignant processes. We present a case of splenogonadal fusion in a 12-month-old healthy male with history of cryptorchidism found at the time of surgery.
RESUMO
BACKGROUND: Baseline and interval dimercaptosuccinic acid (DMSA) scans and urodynamic (UD) studies are often obtained in infants and young children with spinal dysraphism (SD). OBJECTIVE: To identify practical UD parameters which accurately stratify urologic risk young children with SD. STUDY DESIGN: 130 expectantly managed infants/young children with SD and initial DMSA and UD before age 2 were reviewed. End fill pressure (EFP), bladder trabeculations, vesicoureteral reflux (VUR), initial volume (IV) drained at UD catheter placement, and detrusor pressure at initial volume (DPIV) were evaluated for association with subsequent febrile urinary tract infection (UTI), DMSA abnormalities, and early clean intermittent catheterization (CIC). A combination of factors to accurately stratify risk was sought. Groups were compared by log-rank test. The association of CIC and febrile UTI incidence was evaluated. RESULTS: 31/130 patients developed DMSA abnormalities, 52/130 started early CIC, and 61/130 developed a febrile UTI with median follow-up of 3.8 years. Trabeculations, VUR, EFP ≥40 cm H2O, IV ≥50% estimated bladder capacity (EBC), and DPIV >10 cm H2O were associated with subsequent abnormal DMSA scan (p < 0.001). The best predictor was combination of trabeculation and/or VUR (p < 0.001) (Figure). Among patients who maintained a non-trabeculated bladder without VUR during follow-up, 0/51 developed DMSA abnormalities compared with 31/79 who developed one or both (p < 0.001). Patients with trabeculations and/or VUR were more likely to start early CIC (8/51 vs. 44/79; p < 0.001) and have febrile UTI (11/51 vs. 50/79; p < 0.001). In those with trabeculations, CIC was associated with decreased incidence of febrile UTI (incidence rate ratio (IRR) 0.5, 95% CI 0.3-0.9); in those without trabeculations, CIC was associated with increased incidence of febrile UTI (IRR 1.8, 95% CI 1.1-3.1). CONCLUSIONS: VUR, bladder trabeculations, EFP ≥40 cm H20, IV ≥50% of EBC, and DPIV >10 cm H2O were associated with subsequent DMSA abnormalities in young children with SD managed expectantly. Many of these parameters were associated with febrile UTI and early CIC. The combination of trabeculations and/or VUR outperformed other UD parameters in identifying those high and low-risk for adverse urologic outcomes. Routine DMSA scan may have limited utility in patients with a non-trabeculated bladder without VUR, as none developed an abnormal DMSA. Most (71%) abnormal DMSAs were in patients with trabeculations and/or VUR following a febrile UTI. Given these findings and that incidence of febrile UTI may be lower in those with trabeculations while on CIC, patients with trabeculations and/or VUR should be managed aggressively to protect kidneys.

OBJECTIVE: To prospectively correlate pain duration, red scrotal skin, ultrasound appearance of testis, and intraoperative testis color to future testis atrophy after acute testicular torsion. METHODS: Patients 2 months-18 years old with unilateral acute scrotum were consecutively enrolled in a National Institutes of Health transcutaneous near-infrared spectroscopy study, with a subgroup analysis of the true torsion group. Presence or absence of red scrotal skin, pain duration, testicular heterogeneity on preoperative ultrasound, and intraoperative testis color based on a novel visual chart 5 minutes after detorsion were recorded. All testes underwent orchiopexy regardless of appearance. Percent volume difference between normal and torsed testicles on follow-up ultrasound was compared between patients with and without risk factors. RESULTS: Thirty of 56 patients who had surgical detorsion underwent scrotal ultrasound at a mean of 117 days after surgery. A color of black or hemorrhagic 5 minutes after detorsion, pain duration >12 hours, and heterogeneous parenchyma on preoperative ultrasound were associated with significant testis volume loss in follow-up compared with normal testis. All patients with a black or hemorrhagic testis had >80% volume loss. Erythematous scrotal skin was not significantly associated with smaller affected testis volume in follow-up. CONCLUSION: Based on the high atrophy rate, orchiectomy can be considered for testes that are black or hemorrhagic 5 minutes after detorsion. Pain duration >12 hours and parenchymal heterogeneity on preoperative ultrasound were also associated with testis atrophy. Red scrotal skin was not a reliable predictor of atrophy and should not delay exploration.

PURPOSE: Report urologic outcomes among newborns with spinal dysraphism managed within an expectant clean intermittent catheterization (CIC) program. METHODS: Newborns were followed clinically and with serial ultrasound (US). Urodynamics (UD) and dimercaptosuccinic acid (DMSA) renal scan were obtained at 3-6 months, 1 year, 3 years, then as needed. Patients with initial evaluation after 6 months were excluded. RESULTS: Median follow-up was 3.2 years. 11/102 began catheterization for continence (median 4.0 years) and 47/102 did not start CIC. Of these, 2/58 developed a DMSA abnormality. 44/102 began CIC early, often for elevated storage pressures and febrile urinary tract infection (UTI). Of these, 20/44 developed a DMSA abnormality including 9 who had abnormality detected prior to starting CIC. Being on CIC or starting immediately upon recognition of new hydronephrosis, reflux, elevated filling pressures, or febrile UTI was associated with lower chance of DMSA abnormalities (4/17, 24%) compared to delaying CIC (16/27, 60%) (p= 0.03). CONCLUSIONS: CIC can be deferred until continence in select infants with a low risk of significant DMSA abnormality. However, immediate initiation of CIC upon recognition of risk factors is recommended as this was associated with fewer DMSA abnormalities than delaying CIC. Recommendations for expectantly-managed patients include close follow-up, serial US and UD, and prompt initiation of CIC upon recognition of new hydronephrosis, reflux, elevated storage pressures, or febrile UTIs.

INTRODUCTION: Mechanical bowel preparation (MBP) has historically been the standard of care for patients undergoing reconstructive urologic surgery, including urinary diversion. To date, several studies have examined the role of mechanical bowel preparation in postoperative outcomes in pediatric patients undergoing augmentation cystoplasty. However, these patient populations have been heterogeneous in nature, with no studies dedicated to examining the role of MBP prior to reconstructive urologic surgery in pediatric patients with myelomenginoceles. Thus, our objective was to retrospectively assess perioperative measures and postoperative complications after reconstructive urologic surgery with or without mechanical bowel preparation in pediatric myelomeningocele patients. MATERIALS AND METHODS: From 2008 to 2013, 80 patients with myelomeningocele underwent reconstructive urologic surgery involving the use of bowel. Seventy patients underwent a preoperative MBP while 10 did not. Perioperative measures and postoperative complications for these two cohorts were assessed. RESULTS: Eighty patients with myelomeningocele were identified; 70 patients underwent MBP while 10 patients did not. There were no statistically significant differences in demographics or operative time. There were no statistically significant differences in postoperative outcomes including time to first bowel movement and time to tolerating diet. There was also no significant difference in overall complication rate; patients with MBP had 31/70 (44%) complications while 2/10 (20%) of those without MBP had complications (p = 0.18). CONCLUSION: There was no significant difference in perioperative measures and postoperative complications for patients who did not receive a mechanical bowel preparation. Our findings indicate that it is safe and warranted to perform a prospective, randomized study to better characterize the risks and benefits of preoperative bowel preparation for patients with myelomeningocele.

BACKGROUND: MAG3 diuretic renal scan remains the gold standard for determination of improvement in renal drainage following pyeloplasty for ureteropelvic junction obstruction. We hypothesized that (i) a change in geometric measurements between pre-operative and post-operative renal ultrasound (RUS) images and (ii) blinded simple visual review of images both would predict pyeloplasty success. OBJECTIVE: To determine if simple visual review and/or novel geometric measurement of renal ultrasounds can detect pyeloplasty failure. STUDY DESIGN: This study was a retrospective, blinded comparison with a gold standard. Included were children aged ≤18 years undergoing pyeloplasty at our institution from 2009 to 2015. For each kidney, representative pre-operative and post-operative RUS images were chosen. Our standard for pyeloplasty success was improved drainage curve on MAG3 and lack of additional surgery. Measurements for collecting system circularity, roundness, and renal parenchymal to collecting system area ratio (RPCSR) were obtained by three raters (Figure), who were blinded to the outcome of the pyeloplasty. Changes in geometric measurements were analyzed as a diagnostic test for MAG3-defined pyeloplasty success using ROC curve analysis. In addition, six reviewers blinded to pyeloplasty success reviewed pre-operative and post-operative images visually for improved hydronephrosis and categorized pyeloplasty as success or failure based on simple visual review of RUS. RESULTS: Fifty-three repaired renal units were identified (50 children). There were five pyeloplasty failures, four of which underwent revision or nephrectomy. While all geometric measurements could discriminate pyeloplasty failure and success, the geometric measurements that discriminated best between pyeloplasty failure and success were change in collecting system roundness and change in RPCSR. Consensus opinion among six blinded reviewers using simple visual review had a sensitivity of 94% and PPV of 100% with respect to identifying pyeloplasty success (AUC 0.97 (95% CI 0.93-1.0)). This was not significantly different from AUC for change in roundness (p = 0.09) or change in RPCSR (p = 0.1). DISCUSSION: Change in collecting system roundness and change in RPCSR were the most accurate geometric measurements in predicting pyeloplasty success. Simple visual review of ultrasound images for pyeloplasty success performed as well or better than geometric measurements. However, geometric measurements remain useful as a research tool or to communicate findings between clinicians. CONCLUSIONS: Complex geometric measurements of hydronephrosis or post-operative MAG3 scans are not needed if hydronephrosis is visually significantly improved, as simple visual review is highly sensitive for detecting pyeloplasty failure.

PURPOSE: A rapid test for testicular torsion in children may obviate the delay for testicular ultrasound. In this study we assessed testicular tissue percent oxygen saturation (%StO2) measured by transscrotal near infrared spectroscopy as a diagnostic test for pediatric testicular torsion. MATERIALS AND METHODS: This was a prospective comparison to a gold standard diagnostic test study that evaluated near infrared spectroscopy %StO2 readings to diagnose testicular torsion. The gold standard for torsion diagnosis was standard clinical care. From 2013 to 2015 males with acute scrotum for more than 1 month and who were less than 18 years old were recruited. Near infrared spectroscopy %StO2 readings were obtained for affected and unaffected testes. Near infrared spectroscopy Δ%StO2 was calculated as unaffected minus affected reading. The utility of near infrared spectroscopy Δ%StO2 to diagnose testis torsion was described with ROC curves. RESULTS: Of 154 eligible patients 121 had near infrared spectroscopy readings. Median near infrared spectroscopy Δ%StO2 in the 36 patients with torsion was 2.0 (IQR -4.2 to 9.8) vs -1.7 (IQR -8.7 to 2.0) in the 85 without torsion (p=0.004). AUC for near infrared spectroscopy as a diagnostic test was 0.66 (95% CI 0.55-0.78). Near infrared spectroscopy Δ%StO2 of 20 or greater had a positive predictive value of 100% and a sensitivity of 22.2%. Tanner stage 3-5 cases without scrotal edema or with pain for 12 hours or less had an AUC of 0.91 (95% CI 0.86-1.0) and 0.80 (95% CI 0.62-0.99), respectively. CONCLUSIONS: In all children near infrared spectroscopy readings had limited utility in diagnosing torsion. However, in Tanner 3-5 cases without scrotal edema or with pain 12 hours or less, near infrared spectroscopy discriminated well between torsion and nontorsion.

PURPOSE: The TWIST (Testicular Workup for Ischemia and Suspected Torsion) score uses urological history and physical examination to assess risk of testis torsion. Parameters include testis swelling (2 points), hard testis (2), absent cremasteric reflex (1), nausea/vomiting (1) and high riding testis (1). While TWIST has been validated when scored by urologists, its diagnostic accuracy among nonurological providers is unknown. We assessed the usefulness of the TWIST score when determined by nonurological nonphysician providers, mirroring emergency room evaluation of acute scrotal pain. MATERIALS AND METHODS: Children with unilateral acute scrotum were prospectively enrolled in a National Institutes of Health clinical trial. After undergoing basic history and physical examination training, emergency medical technicians calculated TWIST score and determined Tanner stage per pictorial diagram. Clinical torsion was confirmed by surgical exploration. All data were captured into REDCap™ and ROC curves were used to evaluate the diagnostic usefulness of TWIST. RESULTS: Of 128 patients (mean age 11.3 years) 44 (13.0 years) had torsion. TWIST score cutoff values of 0 and 6 derived from ROC analysis identified 31 high, 57 intermediate and 40 low risk cases (positive predictive value 93.5%, negative predictive value 100%). CONCLUSIONS: TWIST score assessed by nonurologists, such as emergency medical technicians, is accurate. Low risk patients do not require ultrasound to rule out torsion. High risk patients can proceed directly to surgery, with more than 50% avoiding ultrasound. In the future emergency medical technicians and/or emergency room triage personnel may be able to calculate TWIST score to guide radiological evaluation and immediate surgical intervention at initial assessment long before urological consultation.

PURPOSE: Bladder outlet procedures without augmentation cystoplasty remain controversial. We hypothesized that bladder outlet procedures without augmentation cystoplasty may lead to unfavorable bladder dynamics, upper tract changes and/or continued incontinence. We reviewed long-term urodynamic, upper tract and continence outcomes following bladder outlet procedures without augmentation cystoplasty. MATERIALS AND METHODS: We retrospectively reviewed all patients who underwent bladder neck reconstruction/closure/sling without augmentation cystoplasty between 2000 and 2014. Because of variation in length of followup, we calculated the cumulative incidence and proportion of cases of upper tract and urodynamic changes, augmentation cystoplasty and subsequent continence procedures. Preoperative factors were compared between patients with and without adverse outcomes. RESULTS: A total of 109 patients underwent bladder outlet procedures without augmentation cystoplasty at a mean age of 8.5 years. At a mean of 4.9 years of followup 59 patients (54%) had undergone additional continence surgery, 20 (18%) had undergone augmentation cystoplasty, 50 (46%) manifested vesicoureteral reflux or hydronephrosis and 23 (21%) had newly diagnosed or worsening renal scarring. At augmentation cystoplasty 13 of 18 patients (72%) had upper tract changes, 15 (83%) had continued incontinence and 11 (61%) had an end fill pressure of greater than 40 cm H2O. All patients had resolution of these changes after augmentation cystoplasty. Patients who had previously undergone vesicostomy or surgery for vesicoureteral reflux were significantly more likely to undergo a subsequent augmentation cystoplasty or to show upper tract changes. CONCLUSIONS: Following bladder outlet procedures without augmentation cystoplasty the estimated 10-year cumulative incidence of augmentation cystoplasty is 30%, continence procedures 70%, upper tract changes greater than 50% and chronic kidney disease 20%. Because of these risks, careful patient selection and close followup are essential if considering a bladder outlet procedure without augmentation cystoplasty.

PURPOSE: Complex urological reconstruction may be facilitated by the improved magnification and dexterity provided by a robotic approach. Minimally invasive surgery also has the potential advantages of decreased length of stay and improved convalescence. We reviewed perioperative and short-term outcomes between robot-assisted and open bladder neck sling/repair with catheterizable channel in patients with neurogenic bladder. MATERIALS AND METHODS: We performed an institutional review board approved retrospective chart review of all patients who underwent open or robotic bladder neck reconstruction without augmentation cystoplasty for refractory urinary incontinence between 2010 and 2014. Age at surgery, operative time, length of stay, complications within 30 days of surgery and future continence procedures (injection of bladder neck/catheterizable channel, additional bladder neck surgery, botulinum toxin A injection) were compared between the groups. RESULTS: A total of 45 patients underwent bladder neck reconstruction (open in 26, robotic in 19) with a mean follow up of 2.8 years. There was no difference in preoperative urodynamics, age at surgery or length of stay (median 4 days in each group, p >0.9). Operative time was significantly longer in the robotic group (8.2 vs 4.5 hours, p <0.001). Three patients (16%) undergoing robotic and 3 (12%) undergoing open surgery had a complication within 30 days (p >0.9). Of patients undergoing open repair 14 (56%) underwent 23 subsequent surgeries for incontinence. By comparison, 8 patients undergoing robotic repair (42%) underwent 12 additional procedures (p = 0.5). CONCLUSIONS: Although a robotic approach may take longer to perform, it does not result in increased complications or length of stay, or worsened continence outcomes.

With the increased application of many different drug classes for the treatment of psychiatric conditions in children, the incidence of priapism has also increased. Priapism of pharmacotherapeutic etiology in the pediatric population is a complex and poorly understood entity that continues to present new management challenges for clinicians. We present 2 cases of pediatric priapism thought to be secondary to the use of pharmacotherapeutic agents. In the first case, sertraline, an antidepressant, and in the second case, atomoxetine, a nonstimulant medication, are implicated as the most likely causative agents. Both medications have a growing association with priapism in the literature.
