ABSTRACT

BACKGROUND: Prune belly syndrome (PBS) is characterized by the triad of abdominal flaccidity, bilateral undescended testicles and genitourinary tract anomalies. A variable spectrum of abdominal wall laxity is observed in PBS. We present the first case of a novel technique using a minimally invasive abdominoplasty to specifically address patients with localized abdominal wall weakness in PBS. CASE PRESENTATION: A two-years-old child with PBS presented with recurrent febrile urinary tract infections. Ultrasonography demonstrated a dysplastic right kidney associated with significant ipsilateral ureterohydronephrosis. Voiding urethrocystogram did not show vesicoureteral reflux and DMSA scan depicted a non-functioning right kidney. During laparoscopic right nephroureterectomy and first stage Fowler-Stephens bilateral orchiopexies, a significant right-sided lateral abdominal wall bulging was observed. A minimally invasive laparoscopic abdominoplasty was performed with a one-way running suture using an unabsorbable 2.0 prolene approximating the edges of the musculofascial defect. While undergoing the second-stage Fowler-Stephens orchiopexy, no bulging was observed. CONCLUSION: A minimally invasive abdominoplasty to improve abdominal wall lateral bulging in PBS was feasible and presented good cosmetic result. We anticipate that this technique can be applied for children with PBS with primary lateral abdominal wall bulging, employing one or more suture lines depending on the fascial defect size.

ABSTRACT

INTRODUCTION: The optimal patient positioning for percutaneous nephrolithotomy (PCNL) based on the complexity of stone burden is not yet defined. Thus, we aimed to evaluate the intraoperative parameters, effectiveness and complications of patients undergoing PCNL between the endoscopic-guided prone split-leg PCNL (ePSL) and the supine PCNL by stratifying patients according to Guy's stone score (GSS). MATERIALS AND METHODS: A retrospective chart review was conducted of patients undergoing PCNL at two high-volume tertiary referral centers. At one center, patients underwent PCNL using the ePSL technique, while at the second center, patients underwent PCNL in supine. Patient demographics and stone characteristics, operative details, complications and effectiveness were compared between groups. The impact of obesity was also investigated. RESULTS: Of 830 subjects, a total of 449 (54%) underwent PCNL in ePSL and 381 (46%) in supine. The ePSL group had a greater mean age and body mass index. No statistical differences were found in gender, serum chemistry and Charlson comorbidity index. After stratifying patients by GSS, the differences in baseline stone burden between PSL and supine lost significance and both groups could be compared. Complications were not statistically different between both groups. Univariate analysis demonstrated that multiple tracts and lower pole access were more prevalent in supine. In addition, for GSS1-3, ePSL was correlated with reduced operative time, radiation exposure, length of hospital stay and need for secondary procedure. Multivariate analysis correlated ePSL with lower radiation exposure and need for secondary procedures (p = 0.01). In comparison to the whole trial population, the same tendencies were appreciated for obese cohort. CONCLUSIONS: This is the first report focusing on the performance differences between ePSL and supine PCNL stratified by GSS. Both techniques are safe, with a low rate of complications. For GSS1-3, ePSL reduces radiation exposure and requires less need for both multiple access and secondary procedure.
