An indwelling urinary catheter or urethral stent are standardly used following a urethroplasty to prevent post-operative urinary retention. There are both closed drainage system (CDS) and open drainage system (ODS) available. The study was designed to determine the outcomes between post-operative CDS and ODS. Fifty-seven hypospadias patients with 66 urethroplasties, performed by a single surgeon, were assessed. During the 40-month study period, the operative outcomes relative to the technique of both urinary catheter drainage systems were evaluated for length of hospital stay (LOS), cost of hospitalization, and post-operative complications. CDS and ODS drainage systems were performed in 32 and 34 operations, respectively. The patient characteristics, the surgical profiles, and post-operative complications were not statistically significant. The CDS/ODS group had median LOS (range) of 9 (1 to 22) 12 (1 to 6) days, respectively, and cost of hospitalization (SD) of 22,908 (4,455)/18,408 (3,848) Bahts respectively. Both had statistical significance, p < 0.001. The subgroup of 26 posterior hypospadias and TIP urethroplasties were also evaluated. Patients with hypospadias given an open drainage system after urethroplasty have a higher rate of early discharge, lower cost of hospitalization, and a lower rate of wound infection.
