Early insertion of a malleable penile prosthesis in ischaemic priapism allows later upsizing of the cylinders

摘要

Objective: Early insertion of a penile prosthesis in prolonged ischaemic priapism is easier to perform than late prosthesis placement, and preserves the penile length. The aim of this study was to assess whether a delayed exchange to an inflatable implant allows upsizing of the cylinders in patients who have undergone early insertion for refractory ischaemic priapism. Materials and methods: Over a 30 month period, 10 patients with ischaemic priapism underwent an early insertion of a malleable penile prosthesis. The mean age was 41.3 years and the mean duration of priapism was 188 h. Following a median period of 130.5 days, all of these patients underwent exchange of the malleable to an inflatable prosthesis. Results: At the time of penile implant exchange, a median upsize in the length of the cylinders of 1 cm in either one or both corporal bodies (range 0-3 cm) was recorded. Five patients had deliberate downsizing at the initial operation owing to a previous shunt. The mean score on the five-item International Index of Erectile Function (IIEF-5) before insertion of the malleable prosthesis was 24 (range 20-25). Three months after the initial insertion of a malleable penile implant the satisfaction rate according to the IIEF-5 score was 80%. Three months after the exchange, the patient satisfaction rate increased to 90%. Conclusion: Insertion of a malleable penile prosthesis is an acceptable option for patients with refractory ischaemic priapism. Although some patients deliberately have a shorter implant inserted initially owing to a previous distal shunt procedure, following a period of resolution the cylinders can be upsized at a later operation.
