Objective:
To evaluate surgical outcome, complications, and patients satisfaction with the Tube (Promedon, Cordoba, Argentina) malleable penile prosthesis in diabetic and non-diabetic patients with refractory erectile dysfunction (ED).
Patients and methods:
The records of 128 eligible patients who received Tube malleable penile prostheses at our institute between September 2008 and October 2015 were reviewed.
Results:
Of the 128 patients, who received Tube penile prostheses at our institute, 53 were diabetics and 75 were non-diabetics. Both groups of patients were comparable for mean age, education level, marital status, hospital stay, time to commencing sexual intercourse, and median follow-up. Complications included: inter-corporeal septal perforation (2.3%), glanular urethral injury (1.5%), acute urinary retention (3.9%), superficial wound infection (7%), penile discomfort (9.4%), and penile prostheses infection (5.5%). Moreover, 3.9% developed atrophy of the cavernosal tissue, 5.5% experienced bad cosmesis, 6.3% experienced ejaculatory disorders, and 2.3% developed bladder calculi. In all, 13 prostheses (9.4%) were removed, seven of them due to infection, three on the patients’ demand and three due to mechanical failure.The satisfaction rates with the prostheses were 77.3% and 79.4% in the diabetic and non-diabetic patients, respectively; with an overall satisfaction rate of 78.5%. There was no significant difference in the complication rate or prostheses infection between diabetic and non-diabetic patients.
Conclusion:
Tube malleable penile prostheses are associated with low complication and high satisfaction rates. There was no significant difference in the complication rate or prostheses infection between diabetic and non-diabetic patients. A
prospective comparative study with a large number of patients is recommended.
