ABSTRACT
BACKGROUND: Complex hypospadias is a surgical challenge.
AIM: To present the long-term outcomes of two-stage repair of complex hypospadias using a scrotal septal flap.
METHODS: This was a retrospective study of patients with complex hypospadias who were operated on between January 1st, 2001, and January 1st, 2019, at a single hospital using a scrotal septal flap (two-stage surgery) or prepuce flap (one-stage surgery; control group). In the scrotal group, the urethra was first repaired using oral mucosa; in the second stage, a scrotal septal flap was used as a second imper-meable layer. Maximal/average urinary flow rates after surgery were compared. All patients were followed for ≥ 6 mo (range: 6-96 mo).
RESULTS: Ninety-seven patients were included (46 in the scrotal group and 51 in the prepuce group). The m aximal urinary flow rate was 15.4 ± 2.1 mL/s in the scrotal group and 14.3 ± 3.0 mL/s in the control group (P = 0.035). The average urinary flow rate was 8.4 ± 2.3 mL/s in the scrotal group and 7.5 ± 1.5 mL/s in the control group (P = 0.019). The proportion of patients achieving good therapeutic effects was higher in the scrotal group than in the control group [24 (52.2%) vs 16 (31.4%), P = 0.042; 34 (73.9%) vs 25 (49.0%), P = 0.014]. The scrotal flap two-stage surgery was independently associated with a higher maximal urinary flow rate (OR = 2.416, 95%CI: 1.026-5.689, P = 0.044) and with a higher average flow rate (OR = 2.484, 95%CI: 1.054-5.854, P = 0.038).
CONCLUSION: In complex hypospadias, a scrotal septal flap could be a versatile and reliable option for resurfacing the penis.
