Intermediate to long-term follow-up indicates low risk of recurrence after Double HIT endoscopic treatment for primary vesico-ureteral reflux

PURPOSE Follow-up of patients undergoing dextranomer/hyaluronic acid injection for vesico-ureteral reflux (VUR) is controversial. The purpose of our study was to test the hypothesis that patients undergoing the double hydrodistention-implantation technique (Double HIT) have a higher clinical and radiographic success rate. MATERIALS AND METHODS Patients undergoing Double HIT endoscopic injection for VUR were prospectively identified. Patients underwent an ultrasound at 6 weeks to assess the implants, and, if visible, prophylactic antibiotics were discontinued and patients were scheduled for a 1-year voiding cystourethrogram (VCUG). Radiographic success was defined as a negative VCUG and clinical success as no febrile urinary tract infections at 1 year. RESULTS A total of 54 patients underwent endoscopic injection for VUR. Twenty-five (51%) were compliant with the 1 year follow-up; 18 non-compliant patients were contacted and their clinical status assessed. Thirty patients eventually completed the 1-year VCUG at a mean of 12.2 months (range 10-20). Among the 60% of patients with 1-year radiographic follow-up, 2 had persistent VUR for a radiologic success rate of 93%. All radiographic failures were infection-free. Of the 80% (43/54) of patients with available clinical data, 3 (7%) had afebrile UTI for a clinical success rate of 93%. CONCLUSIONS The Double HIT leads to a 93% clinical and 93% radiographic intermediate/long-term success rate. With this technique, better outcomes were achieved with fewer recurrences than previously reported. These favorable results challenge the need for postoperative VCUG in asymptomatic patients after the Double HIT.

Sutureless and scalpel-free circumcision--more rapid, less expensive and better?

PURPOSE We previously reported our success with sutureless circumcision using 2-octyl cyanoacrylate in 267 patients. We have since modified our technique by making incisions with electrocautery. We report our results with this novel technique. We also performed a cost analysis. MATERIALS AND METHODS We compiled data on all patients 6 months to 12 years old who underwent primary circumcision and circumcision revision in a 39-month period, as done by 3 surgeons. Study exclusion criteria were complexity beyond phimosis and Gomco clamp use. The technique included 1) a circumferential inner incision using electrocautery on cutting current, 2) a circumferential outer incision using electrocautery, 3) foreskin removal, 4) hemostasis with electrocautery, 5) skin edge approximation with 2-octyl cyanoacrylate or 6-zero suture and 6) antibiotic ointment application. We also determined the cost of all procedures based on anesthesia and operating room facility fees, and material costs. RESULTS Between July 1, 2006 and October 1, 2009 we performed 493 primary circumcisions and 248 revisions using 2-octyl cyanoacrylate, and 152 primary circumcisions and 115 revisions using 6-zero sutures. Mean operative time for primary circumcision and revision using 2-octyl cyanoacrylate was 8 minutes (range 6 to 18), and for sutured primary circumcision and revision it was 27 minutes (range 18 to 48). At a mean 18-month followup (range 1 to 39) 3 patients treated with 2-octyl cyanoacrylate and 2 treated with sutures were rehospitalized for bleeding. When done with electrocautery, the cost of the 2-octyl cyanoacrylate technique was

Magnetic resonance urography for diagnosis of pediatric ureteral stricture.

743.55 less than the sutured technique as long as the 2-octyl cyanoacrylate procedures required less than 15 minutes and the sutured procedures required more than 15 minutes. CONCLUSIONS Combined electrocautery and 2-octyl cyanoacrylate for circumcision is a safe, efficient, financially beneficial, cosmetically appealing alternative to traditional circumcision done with scalpel and sutures.

Evolution of Single Practice Trends in the Surgical Approach to the Undescended Testicle

PURPOSE Ureteral stricture is a rare cause of hydronephrosis in children and is often misdiagnosed on ultrasound (US) and diuretic renal scintigraphy (DRS), requiring intraoperative diagnosis. We evaluated ureteral strictures diagnosed by magnetic resonance urography (MRU) at our institution. MATERIALS AND METHODS Children with ureteral stricture who underwent MRU were identified. Patient demographics, prior imaging, MRU findings, and management were assessed. The efficacy of MRU in diagnosis of stricture was compared with US and DRS. Patients with ureteropelvic or ureterovesical junction obstruction were excluded. RESULTS Twenty-eight ureteral strictures diagnosed by MRU between 2003 and 2013 were identified; 22% of strictures were diagnosed by DRS ± US. The mean age at MRU diagnosis was 2.4 years (range 4 weeks-15 years). Hydronephrosis was the most common presentation, accounting for 20 (71%) cases. Other etiologies included pain (3), incontinence (2), and urinary tract infection, cystic kidney, and absent kidney, present in one case each. A mean of 2.7 imaging studies was obtained prior to MRU diagnosis. Twenty-one (75%) ureteral strictures required surgical intervention, with the approach dependent upon location. CONCLUSIONS MRU provides excellent anatomic and functional detail of the collecting system, leading to accurate diagnosis and management of ureteral stricture in children.

A review of the urologic manifestations of Beckwith–Wiedemann syndrome

PURPOSE The surgical approach to palpable and nonpalpable testicles has changed with increasing use of a single scrotal incision and laparoscopy, respectively. We identified current trends in the surgical approach to undescended testicles in the practice of a single surgeon at our institution. MATERIALS AND METHODS A total of 580 orchiopexies were performed in 554 patients by a single surgeon between January 2002 and July 2009. Study inclusion criteria were palpable and nonpalpable primary undescended testicles. Patients were stratified into groups based on the date of the initial procedure by year. A retrospective chart review was performed and the surgical approach in each patient was recorded as laparoscopic, transinguinal abdominal, inguinal or scrotal. RESULTS During the 7-year period the percent of orchiopexies performed through a single scrotal incision increased from approximately 15% to a high of 63%. The overall percent of cases performed through a standard inguinal incision decreased from 65% to 17% and the percent performed through a transinguinal abdominal approach decreased from 15% to 0% in the 2 most recent years tabulated. The use of laparoscopy increased from 3% to 17%. CONCLUSIONS Substantial trends were observed among the 3 groups. The percent of procedures performed through a scrotal incision increased during the 7-year period while the percent of inguinal and transinguinal abdominal procedures decreased concomitantly with no increase in morbidity. Selected use of scrotal approach orchiopexy is safe and effective for palpable undescended testicles.

Same Setting Laparoscopic Antegrade Continence Enema and Antegrade Bladder Neck Injection for Constipation and Urinary Incontinence in the Spina Bifida Population

OBJECTIVE Beckwith-Wiedemann syndrome (BWS) is a constellation of congenital anomalies that classically presents with macroglossia, abdominal wall defects and gigantism. Although renal and adrenal pathology are the most commonly associated urologic findings of BWS, we report a case of a girl with BWS and symptomatic clitoromegaly, recurrent urinary tract infections and vesicoureteral reflux, followed by a review of the literature regarding urologic manifestations of BWS. MATERIALS AND METHODS A comprehensive review of the literature for renal and non-renal urologic manifestations of BWS was conducted using a computer-based (PubMed) search. The reported renal and non-renal urologic findings are summarized. RESULTS In addition to well-described renal manifestations, a variety of non-renal urologic findings have been reported in patients with BWS. CONCLUSIONS Healthcare providers should carefully evaluate both patients and their family members for urologic manifestations of BWS. Early diagnosis and thorough evaluation allows for potential improved management and prognosis of BWS urologic sequelae, including tumors, cryptorchidism and urinary tract abnormalities.

Pediatric chronic orchalgia.

PURPOSE Fecal impaction and urinary incontinence and are among the most important problems in patients with spina bifida. We report our preliminary results with a minimally invasive approach to these 2 problems, that is same setting laparoscopic antegrade continence enema and antegrade bladder neck injection. MATERIALS AND METHODS We reviewed the charts of all patients who underwent same setting laparoscopic antegrade continence enema and antegrade bladder neck injection between January 1, 2006 and August 1, 2008. Demographic data, surgical indications, operative details and results were recorded. Surgical steps were uniform in all cases. Diagnostic laparoscopy was performed. Two additional 5 mm trocars were placed. The appendix was mobilized to reach skin in the right lower quadrant. The antegrade continence enema channel was matured. A small percutaneous cystotomy was then created via the suprapubic port site. The cystoscope was passed suprapubically and dextranomer/hyaluronic acid was injected in the bladder neck. A suprapubic tube was placed. RESULTS We performed a total of 10 same setting laparoscopic antegrade continence enemas with antegrade bladder neck injection in 4 males and 6 females with a mean age of 9.4 years (range 6 to 13). All patients had a smooth walled bladder on cystogram, and good capacity, good compliance and low leak point pressure on urodynamics. There were no intraoperative complications and all patients were discharged home within 24 hours. At an average 18-month followup (range 12 to 27) all 10 patients were continent of stool and reported marked improvement in daily care. No patient experienced stool or gas leakage via antegrade bladder neck injection. Seven of 10 patients (70%) were continent of urine and no longer wore diapers. CONCLUSIONS Same setting laparoscopic antegrade continence enema with antegrade bladder neck injection is a safe, efficacious, reasonably simple minimally invasive approach to severe constipation and urinary incontinence in patients with spina bifida.

Does compliance status predict clinical status in patients undergoing endoscopic management of vesico-ureteral reflux?

INTRODUCTION Chronic orchalgia, defined as testicular pain lasting > 3 months and interfering with normal activities, is neglected in the pediatric literature. We describe our experience with the evaluation and treatment of pediatric chronic orchalgia patients. MATERIALS AND METHODS Charts were screened to identify patients meeting the criteria for chronic orchalgia. Charts were further reviewed to record the history and physical exam, diagnostic tests, treatment and outcomes. RESULTS 65/982 patients met the criteria for chronic orchalgia. Mean age was 13 and mean duration of pain was 8.6 months. Physical exam findings were normal in 46 patients (70%). 59 patients were managed conservatively with resolution (10/59, 17%) or a single visit (36/59, 61%) in 78%. 13/59 (22%) patients showed either minor improvement or no change in symptoms. 5 non-responding patients were managed by the anesthesia pain service; 4 received epidurals with or without additional oral pain medications with 3 experiencing significant pain improvement. CONCLUSION Conservative management of chronic orchalgia allowed symptoms to subside in the majority of cases. We recommend patients be treated with conservative measures for 1-2 months. If this fails, early involvement of the anesthesia pain service can offer treatment modalities such as epidural analgesia. Surgical management in the face of a normal physical exam does not seem to have a role.

Pediatric UrologyEditorial Comment

OBJECTIVE Previous studies of endoscopic management of vesico-ureteral reflux (VUR) have had non-compliance rates around 50%. We examined success rates of patients non-compliant with a delayed follow up protocol after endoscopic injection for VUR. MATERIALS AND METHODS Patients undergoing Double HIT, dextranomer/hyaluronic acid copolymer endoscopic injection for VUR were enrolled in a 1-year, delayed voiding cysto-urethrogram (VCUG) study. All patients non-compliant with the VCUG were contacted and information on their clinical status was collected. Non-compliant patients were re-scheduled for a VCUG. RESULTS 49/54 (91%) patients underwent endoscopic injection for VUR and completed the 6-week ultrasound. At 1-year 49% (24/49) were non-compliant with a VCUG; 75% (18/24) were contacted and provided clinical information. All but one patient agreed to the VCUG. Patients compliant with the 1-year VCUG showed 96% (24/25) clinical and 92% (23/25) radiologic success rates. Non-compliant patients had an 89% (16/18) clinical success rate; 5 (21%) non-compliant patients underwent VCUGs with a 100% success rate. CONCLUSIONS Long-term compliance remains an issue for patients treated endoscopically for VUR, but compliance does not predict clinical status as both groups have favorable clinical outcomes. The repeat VCUG is a barrier to long-term follow up as only 21% of patients underwent the study.
