PURPOSE: To study the effect of Macroplastique injection on postoperative stress urinary incontinence (SUI) in male patients. PATIENTS AND METHODS: Since 1997, 50 consecutive men with a mean age of 66.0 years (range 51-75 years) suffering from mild to moderate postoperative SUI were treated as outpatients with transurethral Macroplastique injections. Under local anesthesia, 2.5 to 5 mL of Macroplastique was injected adjacent to the external sphincter at 5 or 7 o'clock or both. Forty-six patients had undergone radical prostatectomy, three transurethral prostatic resection, and one cystoprostatectomy with bladder substitution. Patients suffering from detrusor instability were excluded. A standardized 1-hour pad test and the patient's grading of the severity of the incontinence from 0 to 3, where 0 meant leaking took place all the time and 3 that the patient was completely dry, were carried out prior to injection and again at 3 months after each injection. Macroplastique injection was repeated if the initial treatment was not curative. RESULTS: The mean 1-hour pad test loss was 48.3 mL at baseline. After the first injection, 6 patients were completely dry and 28 improved; in the rest, no improvement was achieved. Forty patients underwent a second injection after which, 10 more patients became completely dry and 5 improved significantly. Twenty-three patients underwent a third injection, after which, 9 more patients were completely dry. Fourth injections were given to 8 patients, of whom 5 became dry, 1 improved, and 2 patients did not get any benefit. The total volume of Macroplastique injected ranged from 2.5 to 13.5 mL (mean 7.1 mL). A majority of the patients suffered some dysuria following the injection, but there were no significant side effects. CONCLUSIONS: The preliminary results of endoscopic treatment of mild to moderate postoperative SUI in males with outpatient Macroplastique injections are encouraging. To achieve satisfactory results, repeated injections are needed.
