J Surg Pak Jan ;12(4):170-3.

Objective: To assess usefulness of flexible cystoscope in difficult male urethral catheterization. Study Design: Descriptive case series. Place & Duration of study: Fauji Foundation Hospital and Maryam Memorial Hospital, Rawalpindi during a period of four years. Patients & Methods: In a consecutive series of thirty patients with acute urinary retention and initial difficulty in urethral catheterization, a flexible cystoscope and a guide wire was used to insert the Foley`s catheter. Results: Ten patients (33.3%) presented with acute urinary retention due to benign enlargement of prostate. Five patients (16.6%) required re-catheterization following unsuccessful trial after transurethral resection of prostate. Four patients (13.3%) had carcinoma of prostate. This technique was used five times (16%) to catheterize prior to intravesical instillation of cytotoxic drugs. Two patients (6.6%) had bladder neck distortion due to transitional cell carcinoma of bladder, one (3.3%) had an extravesical haematoma and another one (3.3%) had massive post traumatic clot retention. The procedure was successful in 86.7% of the cases. Difficulty to negotiate the urethra was faced in cases of urethral strictures(6.6%). Conclusion: Flexible cystoscope is a safe, quick and effective method for difficult urethral catheterization in male patients.
