CONCLUSIONS
Staged repair using buccal or inner preputial grafts in crippled hypospadias carries a good success
rate. The most common complication is glanular dehiscence especially in proximal cases.

PURPOSE
The study objective is to compare bilateral external skin tube (BEST) and tubularised incised plate
(TIP) repairs for treatment of proximal hypospadias.
MATERIAL AND METHODS
Between January 2009 and September 2017 92 boys underwent proximal hypospadias (perineum
to proximal penile shaft meatus) repair. BEST repairs were performed in 54 patients and TIP repairs
were performed in 38 patients. The principle of BEST repair is to use parameatal-based flaps with
external foreskin extension for tubularised neourethroplasty. All the operations were done by one
surgeon. Patient data was retrospectively reviewed.
RESULTS
The mean ages were 4.2 and 4.4 years old for BEST and TIP repairs, respectively (p=0.820).
The mean operative times were 141.3 and 146.2 minutes in BEST and TIP repairs, respectively
(p=0.450). The mean catheter time was 8.8 days in the BEST group and in the TIP group was
9.9 days (p=0.004). The mean postoperative hospital stay was 9.3 days in the BEST group and
10.1 days in the TIP group (p=0.062). The mean follow-up times were 12.1 months and 26.2 months
for the two groups respectively (p<0.001). Fistulas occurred in 13/54 (24.0 %) and 8/38 (21.1 %)
of cases in the BEST and TIP repair groups, respectively (p=0.805). Wound bleeding, glans de-
hiscence, recurrence of ventral curvature, and meatal stenosis rates were not statistically different
between the two groups.
CONCLUSIONS
BEST and TIP repairs are equally effective for treating proximal hypospadias. However a BEST
repair requires a shorter catheter time than TIP repair.
