Abstract:
PURPOSE: To evaluate the outcome of transurethral microwave thermotherapy(TUMT) for the treatment of urinary retention due to benign prostatic hyperplasia(BPH) in the high-risk surgical patients. MATERIALS AND METHODS: From November, 1992 to March, 1997, a total of 26 patients with urinary retention due to BPH underwent TUMT with PRIMUS U+R because of poor physical and medical status at the department of urology, Red Cross hospital in Seoul. Mean patient age was 73years(range 58 to 97years), mean prostatic weight was 35gm(range 14gm to 68gm) and mean duration of retention was 1.7 months(range 1 day to 36months). The once or twice 1-hour TUMT session was well tolerated and without significant adverse effect. Patients were divided into responder and non-responder. In responder group who were catheter free after TUMT, peak flow rate and post-void residual urine(PVR) were assessed at 3, or 6, or 12months of follow-up. RESULTS: Of 26 patients, 16 patients were responders(61.5%) after TUMT for the duration of follow-up. The mean peak flow rate and post-voiding residual urine during 12months of follow-up period were 10.4m1/sec(range 3 to 22m1/sec) and 62.8ml(range 0 to 269m1), respectively. There was no major complication. CONCLUSIONS: From these results TUMT appears to be safe and erective treatment modality in the high-risk surgical patients.
