Posterior urethral valves (PUV) are now commonly suspected onantenatal ultrasound, but can present with a broad spectrum ofseverity postnatally. Rarely, the diagnosis is missed until adolescenceor adulthood when the patient usually presents with lowerurinary tract symptoms. We describe an even rarer case of PUV inan adolescent who first presented with renal failure and a palpablelower abdominal mass due to urinary retention. We review theliterature on presentation, natural history and outcomes of bothearly and late presenting PUV cases.

Objective: To report the results of fetal cystoscopic laser ablation of posterior urethral valves (PUV) in a consecutive series in two referral centers. Methods: Twenty pregnant women with a presumptive isolated PUV were treated with fetal cystoscopy under local anesthesia. Identification and fulguration of the PUV by one or several firing-contacts with diode laser were attempted. Perinatal and long-term outcomes were prospectively recorded. Results: The median gestational age at procedure was 18.1 weeks (range 15.0-25.6), and median operation time was 24 min (range 15-40). Access to the urethra was achieved in 19/20 (95%) cases, and postoperative, normalization of bladder size and amniotic fluid was observed in 16/20 (80%). Overall, there were 9 (45%) terminations of pregnancy and 11 women (55%) delivered a liveborn baby at a mean gestational age of 37.3 (29.1-40.2) weeks. No infants developed pulmonary hypoplasia and all were alive at 15-110 months. Eight (40% of all fetuses, 72.7% of newborns) had normal renal function and 3 (27.3%) had renal failure awaiting renal transplantation. Conclusion: Fetoscopic laser ablation for PUV can achieve bladder decompression and amniotic fluid normalization with a single procedure in selected cases with anyhydramnios. There is still a significant risk of progression to renal failure pre or postnatally.

Abdominal Masses

Introduction: Abdominal masses in the neonatal period often present a diagnostic challenge. The aim of this study was to evaluate which urological pathologies cause the formation of a neonatal mass, the diagnostic pathway and surgical outcome. Patients and methods: The medical and radiological records of 30 neonates who were admitted to the Neonatal Surgical Unit of Yorkhill Sick Children Hospital, Glasgow with an abdominal mass over a five-year period (2008-2013) were reviewed. Data collected included demographics, gestational age, radiological investigations, operative findings and complications. Result: Seventeen neonates (9 males, 8 females) were identified with an abdominal mass arising from the urological tract. Four boys were found to have posterior urethral valves while in 4 girls a duplex kidney with a ureterocele was identified. In the remaining 9 patients the palpable mass was caused by: vesicoureteric reflux (n=2), multicystic dysplastic kidney (n=2), polycistic kidney disease (n=1), ectopic kidney (n=1), pelvi-ureteric junction obstruction (PUJO) (n=1), unilocular renal cyst (n=1), PUJO and vesicoureteric junction obstruction (n=1). Nine patients required a form of urinary diversion and in two of these patients a nephrostomy was followed by a pyeloplasty, 2 required incision of ureteroceles, 1 nephrectomy, 1 partial nephrectomy, 1 STING and 1 primary valve ablation. Conclusion: Only 70% of newborns with abdominal masses were diagnosed antenatally, while 30% were detected postnatally. Posterior urethral valves remain the most common cause of a neonatal mass in a male, while duplex kidneys with ureterocele were seen in girls. Half of the patients will require a form of urinary diversion in the neonatal period. The large majority (88%) of abdominal masses of urological origin required surgical intervention.
