“…It can include endoscopic unroofing of ureterocoeles, laparoscopic excision of ectopic limbs, laparoscopic ureteroureterostomy for blind limbs and open nephroureterectomy. 3,6 The present case, with a small SVC, could have been managed conservatively. Laparoscopic excision of the ectopic segment of the ureter with the SVC combined with endoscopic incision of the ureterocoele may be feasible, safe and effective but potential risk factors include infection and recurrence.…”

Inverted Y malformation is a rare variant of ureteral duplication with a marked female predominance. We describe a case of inverted Y ureteral duplication with concurrent ectopic ureteral insertion into a seminal vesicle cyst, a ureterocoele and renal dysgenesis, which occurred in a 29-year-old man with lower urinary tract symptoms, haematospermia and postcoital discomfort. To our knowledge, this is the first reported case with this constellation of urogenital abnormalities. Case historyA 29-old-year man presented with urgency, dysuria, haematospermia and postcoital discomfort of 2 months' duration with left abdominal pain. There was no history of fever or haematuria. His medical history included a left renal agenesis and treated bilateral cryptorchidism. Physical examination revealed a palpable, soft and tender intra-abdominal lump occupying the left lumbar region. Genitourinary examination was unremarkable. Laboratory tests were within normal limits. Abdominal ultrasonography demonstrated a left retroperitoneal cystic mass with a hypoechoic intravesical lesion. Computed tomography (CT) showed a cyst measuring 70mm × 66mm × 57mm, expanding from the left renal fossa to a large filling defect in the left bladder base (Fig 1). A ureterocoele with a hydronephrotic kidney was suspected. A cystic lesion of the ipsilateral seminal vesicle was also noted on CT.On cystoscopy, there was severe elevation of the left hemitrigone with bladder neck obstruction, raising the suspicion of a ureterocoele. The ipsilateral ureteric orifice was not visualised. Magnetic resonance imaging (MRI) demonstrated a seminal vesicle cyst (SVC), which measured 30mm × 18mm × 15mm, and a ureter-like tube expanding from the lower ureter and opening into the cyst (Fig 2).In order to investigate further, transrectal ultrasonography guided puncture of the ureterocoele was performed with aspiration of 260ml of chocolate coloured fluid and injection of contrast inside (Fig 3). Fluoroscopy and x-ray showed opacification of the left vas deferens (Fig 4). The aspirated chocolate coloured fluid contained spermatozoa.A diagnosis of an inverted Y ureter with a stenotic ureterocoele and ureteral ectopia into a SVC was considered. The patient underwent an open midline suprapubic, extraperitoneal approach. The specimen was dissected extravesically and resected completely (Fig 5). Microscopically, the ureterlike tube was lined by urothelial epithelium. There were glomeruli and renal tubules with fetal characteristics in the wall of the cystic kidney, suggesting renal dysgenesis. During the six months following resection, he experienced neither haematospermia nor coital discomfort and denied any voiding difficulties.

“…Our extensive review of the English literature revealed no other case with coexistence of all of these anomalies in the same patient. Aside from potential teratogenic and genetic factors, 6 the coexistence of these several anomalies is difficult to explain.…”

“…Abdominal pain is a major symptom and staghorn calculi in both renal moieties have been reported (Chung et al 2009;Mishra et al 2013). Associations of an inverted L-shaped renal ectopia with inverted-Y ureteral duplication, ectopic ureter, and bicornuate uteruses have also been reported (Liu et al 2010).…”
