Urethral pressure profilometry in artificial urinary sphincter implantation: A case report

Figure 1 Preoperative examination. A: Cystoscopy revealed no urethral stricture, and it was observed that the urethra could not close completely; B: Preoperative urethral pressure profilometry showed that the maximum urethral pressure was 52 cmH2O and maximum urethral closure pressure was 17 cmH2O.

Figure 2 Intraoperative findings. A: Abnormal erection during operation; B: A 4.5-cm cuff was selected and placed; C: During operation, the maximum urethral pressure (MUP) was 53 cmH2O and maximum urethral closure pressure (MUCP) was 50 cmH2O in the inactivated state; the MUP was 112 cmH2O and MUCP was 109 cmH2O in the activated state.

Figure 3 Urethral pressure measured at follow-up. Six weeks after the operation, the maximum urethral pressure (MUP) was 89 cmH2O and maximum urethral closure pressure (MUCP) was 51 cmH2O in the inactivated state; the MUP was 120 cmH2O and MUCP was 92 cmH2O in the activated state.
