“…Only about 65 cases of ureteric valves have been reported since Wolfler described his first case in 1877 [1]. Rabinowitz et al classified ureteric valves as Type I or Type II, with Type I having smooth muscle present within the leaflet and Type II having smooth muscle at the base only.…”

Double trouble: diagnostic dilemma in a rare association of proximal ureteric valve with orthotopic ureterocele—case report

Background Association of the ureterocele and proximal ureteral valve is a rare congenital anomaly which can lead to quick detoriation of renal function due to double obstruction. Though ureteral valves have been associated with other ureteral anomalies, this specific association is extremely rare. Case presentation A 7-month-old boy was referred to us for antenatally detected hydronephrosis. Provisional diagnosis of orthotopic ureterocele with pelviureteric junction (PUJ) obstruction was made based on preoperative imaging. Endoscopic incision of ureterocele was done and retrograde pyelography showed tight obstruction at PUJ which necessitated a pyeloplasty. Examination of resected specimen confirmed a ureteral valve. Postoperatively, the patient had good improvement in kidney function. Conclusion To conclude, congenital ureteral valves are a rare cause of ureteric obstruction and its association with ureterocele is rarer still. Identification of an ureterocele should not deter us from searching for an associated pathology like a ureteric valve when imaging shows more severe hydronephrosis suggestive of more proximal obstruction.

Congenital ureteric obstruction caused by a ureteric valve is an exceedingly rare entity. Our patient, a nine-year-old male, had undergone evaluation for recurrent pain in the abdomen and was diagnosed as a case of left hydronephrosis on ultrasound abdomen. Intravenous urography and magnetic resonance urography showed incomplete duplex system on the right side along with left hydronephrosis and hydroureter. Cystoscopy with left ascending gram followed by excision of lower third of ureter along with valve and Cohen's ureteroneocystostomy was done. Histopathology revealed Type II ureteric valve. A high index of suspicion is required to make a correct preoperative diagnosis.
