Abstract
A 74-year-old male with post-prostatectomy incontinence underwent artificial urinary sphincter replacement due to device malfunction. Three months after the replacement surgery, he presented for a consultation due to a bulging area in his lower abdomen. Computed tomography revealed a hernia of the pressure-regulating balloon (PRB), while the device was working well. In the reparative surgery, reopening the lower abdominal incision, the PRB was carefully restored to its previous position after creating a sufficient submuscular space. As the rectus abdominis fascia showed an adequate strength, the fascia was tightly sutured without using a prosthetic mesh. Thereafter, the patient has been free from incontinence for two and a half years without hernia recurrence. Given the mechanical nature of the device, replacement surgery is sometimes required over time. Tissue fragility due to repetitive surgeries and increasing ambient pressure due to space reduction derived from the PRB deflation could cause PRB hernia. Such cases can be treated under careful manipulation without damaging the device. Considering the future potential need for repeated surgery, it would be preferable not to use prosthetic mesh, as it can cause dense adhesion.
