Abstract
PURPOSE: The technique of active urinary endoscopic vacuum therapy (uEVT) is described. The surgical technique is demonstrated in detail with the help of a video of the operation and which is available online. Vesical fistulas are a rare complication following rectal surgery. The EVT technique is a novel method for treatment of gastrointestinal leakage. This endoscopic procedure has been adapted to treat a large bladder defect after abdominoperineal resection of the rectum with urine flowing out of the perineal wound. MATERIAL AND METHOD: A new open-pore film drainage (OFD) catheter with an external diameter of only a few millimeters has been developed and is constructed from a very thin open-pore double-layered film and a drainage tube. The OFD was inserted into the bladder by means of flexible endoscopy and channeled out through a suprapubic incision. Continuous suction was applied with an electronic vacuum pump to actively drain the urine completely. A passive catheter drainage of urine from the renal pelvis via transurethral single J stent was carried out simultaneously during the complete duration of treatment. The healing process was monitored during and after therapy by intravesical endoscopy. RESULTS: The application of continuous negative pressure via the OFD resulted in total collapse of the bladder. The urine in the bladder was actively and permanently drained through the OFD. Urine leakage from the perineal wound stopped immediately after induction of suction. After 18 days of treatment with the uEVT the bladder defect was healed. After therapy and removal of the catheters the patient had normal micturition. CONCLUSION: A novel small-bore OFD has been developed for EVT. The OFD technique now allows endoscopic application of negative pressure in the bladder. This first successful experience proves uEVT to be a potent interventional alternative in the treatment of bladder defects.
