Attempted transurethral resection of suprapubic catheter.

The patient, a 79-year-old man, had been relieved of his acute retention by means of a Porges 12 F suprapubic catheter. This was noted at preliminary cystoscopy to lie slightly coiled in the bladder. During subsequent transurethral resection of the prostate the loop became embroiled with the catheter and could not be freed. An attempt was made to draw catheter and loop out through the urethra but this only resulted in disintegration of the loop. The shaft of the loop was withdrawn without difficulty but some of the cutting wire was seen to be missing, and on further examination this was found to transfix the shaft of the catheter into which it was fused. Catheter and wire were pulled out through the urethra using biopsy forceps, after which the resection proceeded uneventfully.
