Introduction:Additional cover after neourethra formation to decrease the fistula rate, has been described using the dartos, tunica, denuded skin and corpus spongiosum. The use of corpus spongiosum alone to cover the neourethra is infrequent. The objective of this study was to evaluate the efficacy of spongioplasty alone as an intervening layer in the prevention of urethral fistula following tubularized incised plate urethroplasty (TIPU).Materials and Methods:A prospective study was performed including 113 primary hypospadias cases undergoing TIPU with spongioplasty from June 2010 to March 2012. Correction of chordee was carried out by penile degloving alone in 5, mobilization of urethral plate with spongiosum in 22 and combination of both in 45 cases. Intra-operatively, spongiosum was taken to be poorly developed if it was thin and fibrous, moderate if good spongiosal tissue with good vascularization and well-developed if healthy robust spongiosum, which became bulkier than native spongiosum after tubularisation. Spongioplasty was done in a single layer after mobilization of spongiosum, starting just proximal to the native meatus and into the glans distally.Results:The mean age of the patients was 11.53 years. The type of hypospadias was distal, mid and proximal in 81, 12 and 20 cases respectively. Spongiosum was poorly developed in 13, moderate in 53 and well-developed in 47 cases. The mean hospital stay was 8-10 days and follow-up ranged from 6 months to 2 years. Urethral fistula was seen in six patients (11.3%) with moderate spongiosum (distal 1, mid 1 and proximal 4), and three (23.03%) with poorly developed spongiosum (one each in distal, mid and proximal) with an overall 7.96% fistula rate. None of the patients with well-developed spongiosum developed a fistula. Poorer spongiosum correlated with a greater number of complications (P = 0.011). Five out of thirteen cases with poor spongiosum (38.46%) had proximal hypospadias, i.e. more proximal was the hypospadias, poorer was the development of the spongiosum (P = 0.05). Meatal stenosis was seen in two patients (1.76%) with proximal hypospadias, one with moderate and the other with poorly developed spongiosum. More proximal was the hypospadias, greater were the number of complications (P = 0.0019).Conclusion:TIPU with spongioplasty reconstructs a near normal urethra with low complications. Better developed and thicker spongiosum results in lower incidence of fistula and meatal stenosis. More proximal hypospadias is associated with poorer spongiosum. We recommend spongioplasty to be incorporated as an essential step in all patients undergoing tubularized incised-plate repair for hypospadias.

Introduction:Physicians frequently encounter questions by parents regarding the normal size of a child's penis. We evaluated normal variations of penile dimensions, correlation of penile length with height, weight, and body mass index (BMI) of boys and analyzed the differences in penile dimensions from those reported from other countries.Materials and Methods:A cross-sectional study was conducted at our institution during October 2012-December 2012. A total of 250 subjects (birth to 10 years) were evaluated and divided into 10 groups with 1-year interval taking 25 children in each. Penile dimensions measured twice by a single observer with Vernier calipers included the length of flaccid penis fully stretched and diameters at mid-shaft and corona. Diameters were multiplied by pi (π = 3.14) to calculate circumferences. Mean, standard deviation, and range were calculated. Height, weight, and BMI were noted and statistically correlated with the penile length using the Pearson correlation coefficient. Data were compared with similar studies reported on other populations in the past and individually evaluated with every study using Student's t-test.Results:The mean values for the penile length, mid-shaft circumference, and coronal circumference were 3.34, 3.05, 3.29 cm during infancy, 4.28, 3.86, 4.11 cm during 4-5 years, and 5.25, 4.78, 5.05 cm during 9-10 years, respectively. The penile length increased with advancing age in successive age groups, but it did not have a direct correlation with either height, weight, or BMI. Penile dimensions in North Indian children were found to be statistically smaller in comparison with most studies from other countries.Conclusion:We provide the normal range and variations of penile dimensions in North Indian children.

Objective:The megameatus variant of anterior hypospadias with an intact complete foreskin occurs in approximately 1%–3% of hypospadias. Hence, the objective of the study was to evaluate the results of tubularized urethral plate urethroplasty (TUPU) in megameatus intact prepuce (MIP).Materials and Methods:A retrospective study (June 1996–June 2015) of MIP from our hypospadias registry was conducted. All patients with megameatus, either with an intact prepuce or with one previously removed, were included in the study. Case sheets of clinical records, investigations, clinical photographs, and videos were reviewed. Patients were classified into, glanular, coronal, subcoronal, and distal penile. TUPU were done. Patients were called for follow-up at 1, 3, 6, and 12 months postoperatively, and then yearly for the assessment of the cosmetic appearance and fistula, meatal stenosis, or other complications.Results:Of 1026 patients with hypospadias, we identified 13 cases of megameatus variant of hypospadias; three of the 13 had been circumcized previously. Glanular approximation was done for the one patients of the glanular variant, and another had frenuloplasty. These two patients were excluded from the study. Incision in the inner preputial skin was closed in 10 patients to have an intact prepuce. Follow-up period varied from 6 months to 4 years (median follow-up 2½ years). None of the patients developed complications such as fistula, meatal stenosis, and/or wound dehiscence.Conclusions:Surgical correction of MIP in the era of increased cosmetic awareness is justified. Excellent results are obtained with TUPU and along with spongioplasty and frenuloplasty because of availability of wide urethral plate and well-developed spongiosum in these patients. TUPU should be the preferred procedure in cases of MIP.
