Abstract
BACKGROUND
Endometriosis is a chronic, debilitating condition affecting up to 10% of reproductive-age women. Urinary tract endometriosis is found in 1%-6% of women diagnosed with pelvic endometriosis, with the most common sites being the bladder (70%-85%), ureter (9%-23%), and kidney (4%). Patients typically present with symptoms such as lower abdominal pain, dysuria, and urgency. Unfortunately, urinary tract endometriosis is often asymptomatic, potentially leading to silent obstructive uropathy and kidney failure.
OBJECTIVE
To demonstrate a step-by-step approach for the surgical management of urinary tract endometriosis using conventional laparoscopy for partial cystectomy and robotic-assisted laparoscopy for ureteroneocystostomy.
MATERIAL AND METHOD
Surgical video of 2 cases managed in an academic tertiary referral center for endometriosis. The first case was a 38-year-old Gravida 3, Para 3 with a history of hysterectomy who had an MRI which revealed a T2 hypointense bladder nodule consistent with endometriosis. Patient had significant urinary urgency, dysuria, and suprapubpic pain that improved but did not disappear after starting oral progestin therapy (5 mg of norethindrone). A cystoscopy was first performed to confirm MRI findings of bladder lesion and to delineate borders and depth of invasion. The second case was a 35-year-old nulliparous woman with chronic pelvic pain and primary infertility. The patient had a history of stage IV endometriosis with deep endometriosis into the bowel and extrinsic encasement of the ureters causing subsequent hydronephrosis requiring bilateral ureteral stents. She had continued daily pelvic pain despite of being on oral contraceptives for medical management of endometriosis. She subsequently underwent bilateral percutaneous nephrostomy tube placement to allow for ureteral rest prior to surgery.
RESULTS
In the first case, conventional laparoscopy was utilized to perform bilateral ureterolysis, bladder mobilization, partial cystectomy for complete excision of the lesion, and 2-layered bladder closure. Use of indigo carmine assisted with ureteral orifice identification. In the second case, a cystoscopy was performed with injection of Indocyanine green to assist with ureteral identification. After ureterolysis, distal ureteric obstruction due to extensive disease was confirmed on laparoscopy and ureteroscopy. Bilateral ureteroneocystostomy with placement of Double-J ureteral stents was performed using a robotic-assisted approach. Each patient had an indwelling Foley catheter for bladder decompression during recovery. Pathology in both cases revealed endometriosis. Both patients had an uneventful postoperative course. A postoperative retrograde cystogram confirmed adequate repair prior to removal of each Foley catheter. Patient 2 had uncomplicated office stent removal 6 weeks postoperatively and had a normal renal ultrasound with no hydronephrosis 6 months postoperatively.
CONCLUSION
Endometriosis is an increasingly common condition. It is important for gynecological surgeons to have the proper understanding of anatomy, surgical technique, and multidisciplinary care needed with urology for safe and complete excision of bladder and ureter endometriosis.
