Self-retaining intraurethral stent: an alternative to long-term indwelling catheters or surgery in the treatment of prostatism

The self-retaining intraurethral coil is a device to stent the urethra in men who have severe urethral obstruction. It allows them to empty their bladders and still remain continent and sexually active. The device can be used in place of long-term indwelling catheters or as an alternative to surgery. During 1 year, we inserted the stent in 26 men who were poor operative risks. The treatment was successful in 20 (77%). All 20 were able to void satisfactorily. Four of the 20 resumed sexual activity, which previously had been prevented by indwelling catheters. Two patients who had delayed prostatic surgery because of fear of impotence were able to empty their bladders properly and to remain sexually active. Three patients subsequently had surgery, two after anticoagulant therapy could be stopped and one after renal function improved. No difficulties caused by the stent were encountered during surgery. Follow-up was for 2-12 months. Four patients who had had the stent in place for 12 months had no difficulties. In 16 of the 18 patients who had indwelling catheters and infected urine before insertion of the stent, sterilization of the urine was obtained after relatively short courses of antibiotic treatment. Short-term complications associated with the stent were incontinence or urinary retention. These were treated by repositioning the stent. Frequency of urination after insertion of the stent either disappeared spontaneously or was treated with anticholinergic drugs. In six patients, frequency was so severe that removal of the stent and insertion of an indwelling catheter were necessary. Slight to mild dysuria occurred immediately after surgery in all patients but eventually disappeared. Our experience suggests that the self-retaining intraurethral stent has considerable promise for the treatment of prostatic obstruction of the urethra.
