Abstract:
We describe the use of a short, rigid ureteroscope to place a Foley catheter into the bladder under direct vision. The Circon ACMI MICRO-6 short ureteroscope was passed through a 22F Foley catheter modified with a catheter punch device. The catheter was placed rapidly and without difficulty in 2 patients with significant undermining of the trigone after transurethral incision of the prostate. This technique is rapid, simple, and avoids the potential complications of blind catheter placement following difficult transurethral procedures.
