Bladder neck incision in infants

INTRODUCTION: The Macedo ileal catheterizable channel was published in 2000 and consists of an enterocystoplasty with a catheterizable channel that precludes the need of the appendix for the efferent channel. After 25 years of experience with this technique, we decided to review our experience in a select subgroup of cases performed and followed exclusively by the author in a non-teaching hospital facility after the latest modifications of the procedure. MATERIALS AND METHODS: Since 2008, we have refined our technique with the following modifications: small skin transverse incision instead of longitudinal one, with a semicircular flap for further stoma creation in the midline and importantly the scissors maneuver...

INTRODUCTION: Management of obstructing ureterocele often includes endoscopic transurethral incision (TUI) that can be challenging secondary to uncertainty in anatomic landmarks with risk of serious complications. To this end, we innovated a technique using predictable landmarks that begins endoscopic incision at the ureterocele orifice and extends retrograde proximal to the bladder neck (Figure). OBJECTIVE: With over 15 years of experience in performing this retrograde incision from orifice (RIO) technique, we aimed to examine post-operative outcomes and risk of surgical failure after RIO compared to traditional TUI techniques for ureteroceles...

INTRODUCTION: Vesicoureteric reflux (VUR), recurrent urinary tract infection (RUTI), febrile urinary tract infection (FUTI), renal scarring, and renal damage are intimately related. Key factors of renal damage in VUR are suspected to be RUTI and FUTI. Hence, conventional treatments are targeted toward the prevention of RUTI and FUTI. However, literatures have witnessed that control of infection is not sufficient enough. That means we are missing some hidden, enigmatic, or overlooked factors which are essentially responsible for renal damage...

Objective: The objective of the study was to share our experience of management of posterior urethral valve (PUV) and to suggest a paradigm to impede upstaging of chronic kidney disease (CKD) and prevent end-stage renal failure (ESRF). Patients and Methods: We have treated 332 patient of PUV from March 2005 to April 2016, Of which 272 case records had adequate data to be analyzed. The mean age was 2.48 years (range: 1 day-18 years). We did primary fulguration in 231 patients, of which five patients needed bilateral ureterostomy for obstinate high creatinine level...

INTRODUCTION: Detrusor dysfunction is known to persist in several patients of Posterior Urethral Valve (PUV) after successful fulguration leading to progressive deterioration of renal function. Persistent bladder outlet obstruction (BOO) in the form of bladder neck hypertrophy, residual valves or strictures may contribute to progressive detrusor dysfunction. These are assessed radiologically or cystoscopically and are managed variedly by anticholinergics, alpha-adrenergic blockers or even bladder neck incision...

PURPOSE: Concurrent valve ablation and bladder neck incision is suggested as an effective and safe treatment approach in posterior urethral valve children with prominent bladder neck. We evaluated chronic kidney disease risk factors in these children. MATERIALS AND METHODS: We retrospectively reviewed medical records of children with posterior urethral valve and included those younger than 18 years old who underwent valve ablation and bladder neck incision at our institution...

BACKGROUND: Trans-umbilical colostomy (TUC) has been previously created in patients with Hirschsprung's disease and intermediate anorectal malformation (ARM), but not in patients with high-ARM. The purposes of this study were to assess the feasibility, safety, complications and cosmetic results of TUC in a divided fashion, and subsequently stoma closure and laparoscopic assisted anorectoplasty (LAARP) were simultaneously completed by using the colostomy site for a laparoscopic port in high-ARM patients...

OBJECTIVE: To evaluate the effectiveness of endoscopic surgery before or after definitive correction in patients with a persistent cloaca. MATERIALS AND METHODS: The medical records of 16 patients diagnosed with persistent urogenital sinus at our institution were retrospectively reviewed. Of these 16 patients, five underwent endoscopic surgery, such as visual internal urethrotomy or transurethral incision by a single surgeon at the time of or after colostomy formation or corrective surgery...

OBJECTIVE: To represent our experience in the management of posterior urethral valves and concomitant vesicoureteral reflux (VUR). METHODS: A total of 326 children with posterior urethral valve who had underwent valve ablation/bladder neck incision were studied, and those who had persistent VUR and were categorized under 3 main groups were followed up. Group 1 (n = 71) received prophylactic antibiotic, group 2 (n = 50) underwent Deflux injection (2a) (n = 28): Deflux injection alone, group 2b (n = 22) Deflux with concomitant autologous blood injection (HABIT), and group 3 (n = 19) underwent ureteroneocystostomy before referral and was followed up conservatively...

OBJECTIVE: To present two cases of type IIA urethral duplication and propose a reproducible surgical approach. METHODS: Two cases are presented in this report. The first was a male child with a type IIA1 urethral duplication with two urethral channels arising from the bladder through separate bladder necks coursing to the glans penis. The second infant had a type IIA2 urethral duplication with a single bladder neck. Both children were repaired using a surgical approach that joined both urethral openings into a single orthopic meatus...

OBJECTIVE: To report a novel surgical approach for single-stage repair of exstrophy-epispadias, with the specific aim of innervation, preserving sphincteroplasty corporal detachment for penile lengthening and ischio-pubic ramotomy for Linia-alba approximation. MATERIAL AND METHODS: Twenty-five classic exstrophy with compliant bladder plate and 10 incontinent epispadias patients were selected. Preoperative magnetic resonance angiogram of urogenital diaphragm showed triangular space between ischio-cavernosus, bulbo-spongiosus, and transverse-perinei muscles containing sphincteric branch of perineal artery indicating the course of sphincteric nerve...

PURPOSE: Most attempts to create an umbilicus in the exstrophy abdomen eventually leave the end result of a flat scar rather than an inverted structure. We describe a technique that allows the creation of a better looking inverted umbilicus. MATERIALS AND METHODS: A total of 19 patients between 5 days and 7 years old underwent umbilicoplasty. At the apex of the vertical midline wound the skin and superficial fascia are elevated off the anterior rectus sheath well beyond the top of the skin incision...

PURPOSE: We evaluated the effects of simultaneous bladder neck incision and valve ablation on urodynamic abnormalities in patients with posterior urethral valves. MATERIALS AND METHODS: A total of 46 patients with posterior urethral valves entered our prospective study between 1998 and 2003. Group 1 consisted of 22 patients who underwent simultaneous valve ablation and bladder neck incision at the 6 o'clock position. Group 2 consisted of 24 age matched patients with comparable prognostic factors who underwent simple valve ablation...

OBJECTIVE: To investigate whether myogenic bladder decompensation in patients treated for congenital posterior urethral valves (PUV, the most serious cause of infravesical obstruction in male neonates and infants) may be secondary to bladder neck obstruction, as despite prompt ablation of PUV these patients can have dysfunctional voiding during later childhood or adolescence, the so-called 'valve bladder syndrome'. PATIENTS AND METHODS: The study comprised 18 boys (mean age 14 years, range 6...

PURPOSE: The surgical correction of primary vesicoureteral reflux (VUR) is highly successful. This success decreases in more complex cases and often involves reoperation and increased morbidity. We present our experience with the use of subureteral injection of dextranomer/hyaluronic acid (Dx/HA) in complex cases of vesicoureteral reflux in which open surgery would have been indicated. MATERIALS AND METHODS: Between October 2001 and July 2003, 72 patients 9 months to 31 years old (mean age 5...

Ureterocele is a cystic dilatation of the intravesical ureter that is most commonly observed in females and children, and usually affects the upper moiety of a complete pyeloureteral duplication. According to their position, ureteroceles are divided into intravesical, when the ureterocele is completely contained inside the bladder, and extravesical when part of the cyst extends to the urethra or bladder neck. Most ureteroceles are diagnosed in utero or immediately after birth during an echographic screening of renal malformations...

PURPOSE: Laparoscopic assisted surgery results in an improved cosmetic appearance by allowing complex reconstruction without a midline upper abdominal incision. We report technique and outcomes in patients undergoing laparoscopic assisted reconstruction during a 7-year period. MATERIALS AND METHODS: A total of 31 consecutive patients with a mean age of 14 years (range 1 to 36) underwent laparoscopic assisted reconstructive surgery through a lower midline or Pfannenstiel incision by a single surgeon (SGD) between June 1995 and July 2002...

PURPOSE: Continence is a difficult goal in exstrophy-epispadias complex repair. It is presumed that all anatomical components involved in the exstrophy-epispadias abnormality are present but laterally and anteriorly displaced. The penile disassembly technique for epispadias restores the normal anatomical relationship of the male genital components. Its extension to complete primary bladder exstrophy closure enables deeper positioning of the bladder neck within the pelvic diaphragm. We identified the perineal striated muscular complex and present its appropriate periurethral reassembly as a main step in exstrophy-epispadias complex repair...

PURPOSE: The treatment of ectopic ureterocele is controversial. In addition to debate on optimal therapy, discussion exists on whether there is further risk of deteriorating bladder function after extensive bladder surgery during the first year of life, which is a reason to postpone surgery. In a prospective nonrandomized trial we treated 40 patients regardless of age who had ectopic ureterocele with complete surgical reconstruction of the lower urinary tract and upper pole resection of poorly functioning upper pole moieties at referral...

PURPOSE: Endoscopic incision was performed as the initial therapy for ureteroceles in children presenting to our institutions between 1985 and 1990. To assess the long-term efficacy of this treatment modality we reevaluated the outcome of these patients. MATERIALS AND METHODS: Parameters reviewed included patient age at surgery, position of the ureterocele, a duplex system, preoperative and postoperative reflux, and the need for additional operations. Statistical analysis consisted of chi-square and Wilcoxon's rank sum tests...
