This case report describes a 39-year-old woman with flank pain and hematuria whose ureteric obstruction and non-functioning kidney were caused by endometriosis of the bladder, successfully treated with hysterectomy and bilateral salpingo-oophorectomy.

This 2012 case report describes a 39-year-old woman with flank pain and haematuria; imaging showed unilateral hydronephrosis and impaired renal function, and cystoscopy revealed a soft tissue mass at the left ureteric orifice causing obstruction. Biopsy and histology identified tubal-type epithelium compatible with endosalpingiosis, and later formal histology after more definitive surgery showed endometriosis in the resected specimen, with persistent symptoms leading to hysterectomy, bilateral salpingo-oophorectomy, and partial cystectomy. The major caveat is that the findings are limited to a single patient and cannot establish incidence or broader causal mechanisms. Relevance to endometriosis: the paper’s key diagnosis on final histology is urinary tract endometriosis (at the vesico-ureteric junction), reported as an unusual cause of haematuria.

Abstract

A 39 year old lady presented with flank pain and haematuria. Radiological investigations showed unilateral hydronephrosis and a serum creatinine of 102?mol/l. At cystoscopy, a soft tissue mass was found in the region of the left ureteric orifice and was causing obstruction of the ureter. A resection biopsy of this lesion was taken. A CT scan and DTPA renogram showed a non-functioning left kidney secondary to chronic obstruction by a soft tissue mass at the left vesico-ureteric junction. Histological analysis of the endoscopic resection specimen showed that the mass contained tubal-type epithelium compatible with a diagnosis of endosalpingiosis (a rare variant of Mullerianosis of the urinary tract). In view of persistent symptoms, it was decided to proceed to surgery. A hysterectomy, bilateral salpingo-oophorectomy and partial cystectomy were performed. The patient has recovered well and is currently asymptomatic. Formal histology of the resection specimen showed the presence of endometriosis.
