Aim: To describe a technique of phalloplasty that is devoid of donor site scarring and suitable for urethral inlay and penile prosthesis in subsequent stages in cases of aphallia. Materials and Methods: Four patients with various disorders of sex development with 46 XY and severe penile deficiency, including one with complete androgen insensitivity syndrome who was initially raised as female, have been operated using a "Bird Wing" lower abdominal skin crease incision. Results: The patients' age ranged from 6 to 17 years with preoperative stretched penile lengths between 1 and 2.5 cm. Phallic sizes between 7.5 and 12.5 cm was achieved leaving the donor site unremarkable with lower abdominal skin crease linear scar and excellent postoperative recovery. Conclusions: This phalloplasty technique can be utilized as a definitive procedure in many situations of penile insufficiency. Subsequent stages of urethral repair and insertion of penile prosthesis can be easily added.

Aim: To evaluate and compare the extent of surgical stress following laparoscopic nephrectomy (LN) and open nephrectomy (ON) in children. Materials and Methods: Twenty consecutive children undergoing nephrectomy were randomized to LN or ON groups. Acid-base balance, blood glucose, acute phase proteins (C-reactive protein [CRP]) and inflammatory markers (interleukin-6 [IL-6]) were measured pre-operatively, as well as 4 and 24 h after surgery. The differences between the two groups were analyzed statistically (significance value for P < 0.05). Results: The overall acid base status was more stable in LN. The fall in pH 4 h after surgery was more in ON (P = 0.440) and the difference in pH in ON 4 h and 24 h post-operatively was statistically significant (P = 0.002). In LN, significant difference was found in the base excess mean pre-surgery (mean -3.280 mEq/L) and 4 h post-surgery (mean -7.480 mEq/L) (P = <0.05), as well as between 4 h and 24 h after surgery (mean -2.660 mEq/L) (P = 0.011).The acute rise in CRP 24 h post-operatively in the ON (88.972 mg/L) was significantly higher when compared to both the pre-operative and 4 h post-operative values (P < 0.05). This rise was however, not statistically significant when compared to the 24 h post-operative value in LN (46.399 mg/L) (P = 0.062). The rise in IL-6, 24 h post-procedure in LN (mean 44.444 pg/ml) was statistically lower than that in the open group (mean 343.333 pg/ml) (P = 0.041). Conclusions: The stable acid-base status and lesser rise of CRP and IL-6 in LN lead to the conclusion that surgical stress caused by LN is less than ON.

Aims: To study, the effects of ipsilateral ureteric obstruction on contralateral kidney and the role of renin angiotensin system (RAS) blockade on renal recovery in experimentally induced unilateral ureteric obstruction. Materials and Methods: Unilateral upper ureteric obstruction was created in 96 adult Wistar rats that were reversed after pre-determined intervals. Losartan and Enalapril were given to different subgroups of rats following relief of obstruction. Results: The severity of dilatation on the contralateral kidney varied with duration of ipsilateral obstruction longer the duration more severe the dilatation. There is direct correlation between renal parenchymal damage, pelvi-ureteric junction (PUJ) fibrosis, inflammation and severity of pelvi-calyceal system dilatation of contralateral kidney with duration of ipsilateral PUJ obstruction. Conclusions: Considerable injury is also inflicted to the contralateral normal kidney while ipsilateral kidney remains obstructed. Use of RAS blocking drugs has been found to significantly improve renal recovery on the contralateral kidney. It can, thus, be postulated that contralateral renal parenchymal injury was mediated through activation of RAS.

Aim: To share our experience of doing tubularized incised plate urethroplasty with modifications. Materials and Methods: This is a single surgeon personal series from 2004 to 2009. One hundred patients of distal hypospadias were subjected for Snodgrass urethroplasty with preputioplasty. The age range was 1 to 5 year with mean age of 2.7 years. Selection criteria were good urethral plate, without chordee and torsion needing complete degloving. Main technical modification from original Snodgrass procedure was spongioplasty, preputioplasty, and dorsal slit when inability to retract prepuce during surgery. Results: Average follow-up period is 23 months. Seven (7%) patients developed fistula and one patient had complete preputial dehiscence. Phimosis developed in three (3%) patients and required circumcision. Dorsal slit was required in seven patients. One patient developed meatal stenosis in postoperative period. All other patients are passing single urinary stream and have cosmesis that is acceptable. Conclusions: Modified tubularized incised plate urethroplasty with preputioplasty effectively gives cosmetically normal looking penis with low complications.

Aim: To evaluate the efficacy of calretinin immunostaining in diagnosing Hirschsprung's disease (HD). Materials and Methods: Sixty cases were studied over a period of 1 year (July 2010-June 2011). There were 36 full-thickness biopsies and 24 resected specimens. Calretinin processing was done on the paraffin-embedded blocks after routine histopathological examination. Results: Of the 36 biopsy specimens, in 19 cases HD was diagnosed by hematoxylin and eosin (H and E) staining earlier. In 2 patients, ganglion cells were seen and HD was ruled out. In 15 cases, there was a diagnostic dilemma and calretinin was used. Ganglion cells were found in 3 specimens and nerve fibers in 5. In all 24 resected specimens, calretinin correlated with the findings on H and E staining. Conclusions: Calretinin was extremely useful in solving the suspicious and indeterminate cases of HD. It can serve as a valuable cost-effective diagnostic aid in the centers where acetylcholinesterase enzyme histochemistry is not available.

Aim: To evaluate the outcome of innervation preserving sphincteroplasty along with anatomical bladder neck reconstruction (IPS-ABNR) compared to classic Young-Dees-Leadbetter (YDL) bladder neck reconstruction in exstrophy with insufficient bladder capacity requiring detubularized-ileocystoplasty. Materials and Methods: Sixteen male patients of exstrophy bladder who required ileocystoplasty from 2004 to 2010 were randomized into group A (n = 7) and group B (n = 9). After detubularized-ileocystoplasty with Mitrofanoff stoma and ureteric reimplantation in all, group A received YDL bladder neck repair while group B received IPS-ABNR repair through a midline scrotoperineal approach. Outcome measurement included operative and postoperative problems, continence, and upper tract status. Results: In group A, two had incompetent bladder neck with gross incontinence, while four had a dry interval of more than 3 h without the ability of voiding per urethra. In group B, seven patients had dry interval of more than 3 h with an ability of urethral voiding and midstream holding in five. Conclusions: Exstrophy patients requiring augmentation cystoplasty and repaired with IPS-ABNR can achieve dynamic bladder outlet resistance with adequate leak point pressure and ability to void voluntarily with midstream holding capability. The children had the satisfaction of voiding per urethra with ability to stop in midstream similar to that in normal children.

Aim: To study renin angiotensin system (RAS) activity after posterior urethral valve ablation and the role of early induction of angiotensin converting enzyme-inhibitors (ACE-I) on the outcome of renal function. Materials and Methods: Thirty four children underwent valve ablation in which therapy with ACE-I was started 40.5 ± 4.1 (range 32-47 months) formed the study group. Post-ACE-I data were collected after mean duration of 18.2 ± 4.0 (12-28 months). Plasma renin activity (PRA), urinary micro albumin, glomerular filtration rate (GFR), and serum creatinine, before and after therapy were monitored. Results: Therapy with ACE-I resulted in a fall in micro albuminuria by 45.7% and 42.0% in patients without and with vesico ureteral reflux, respectively, and improvement in split renal function by 6.6% and 5.9% GFR respectively. A similar response was noted in patients without and with renal scars. Conclusion: The decline in renal function after valve ablation is accompanied by activation of RAS reflected in a gradual rise in PRA. Therapy with ACE-I stabilizes and then improves renal function, thereby, retarding the pace of renal damage.

We report a rare case of prune belly syndrome associated with congenital pouch colon, which was managed successfully.

This report describes a girl with congenital pouch colon (CPC), uterus didelphys with septate vagina, and a cloacal anomaly. The girl underwent cloacal reconstruction at the age of 15 months. Subsequently, at puberty, the child had primary amenorrhea with severe cyclic abdominal pain due to endometriosis of both the uteruses and adnexal cysts with hematometra and hematosalpinx. Laparotomy with removal of both uteri and the left fallopian tube was performed. Both uteri had atresia of the cervix uteri. This report emphasizes the need for comprehensive evaluation and a long-term management strategy for associated gynecologic anomalies in girls with CPC, especially with regard to patency of the outflow tract.

Extrahepatic portal hypertension is not an uncommon disease in childhood, but isolated inferior mesenteric portal varices and lower gastrointestinal (GI) bleed have not been reported till date. A 4-year-old girl presented with lower GI bleed. Surgical exploration revealed extrahepatic portal vein obstruction with giant inferior mesenteric vein and colonic varices. Inferior mesenteric vein was joining the superior mesenteric vein. The child was treated successfully with inferior mesenteric - inferior vena caval anastomosis. The child was relieved of GI bleed during the follow-up.

Paratesticular germ cell tumors are extremely rare. A 12-month-old boy with yolk sac tumor involving only the paratesticular tissue is reported. Pre-operatively raised alpha fetoprotein levels fell to normal levels after high inguinal orchiectomy. This appears to be the youngest and only the 3 ^rd case reported in the English literature.

A case of unilobar Caroli's disease in an 8-year-old girl treated with left hepatectomy is reported here.
