Pediatric urolithiasis is an uncommon disease with incidence varying widely throughout the world. We present our experience in pediatric PCNL in 20 pediatric patients with urolithiasis. Case records of all patients under 14 years of age who presented with urolithiasis from 2016 March to February 2017 were retrospectively reviewed and analyzed with respect to demographic details, clinical presentation, stone characteristics, PCNL puncture site, number, stone clearance, ancillary procedures used, complications, and follow-up status of the children. Associated biochemical abnormalities were also reviewed.   There were 25 renal units in 20 patients (5 had bilateral stones). The mean age at presentation was 8.4 years. There were 15 males and 5 females. The most common presenting symptom was flank pain (n=19/20).There were solitary stones in 17 renal units: 2 stones in 6 renal units and multiple stones in 2 renal units. The average stone size was 1.5cm. Four patients had staghorn calculi. Five patients required two punctures of whom 3 had bilateral disease and 2 had staghorn calculi. The sheath used ranged from 18 Fr to 22 Fr. The nephrostomy tube and DJ stent were kept in all patients.The duration of the procedure at a single site ranged from 45 minutes to 75 minutes. Complete clearance was achieved in 19 patients while one patient required bilateral URS. Three patients had mild fever post-operatively. None of the patients required blood transfusion. Hypocalcaemia was detected in 7 patients. PCNL is safe and effective for treating urolithiasis in children. Keywords: PCNL; Urolithiasis; Pediatric.

The modified Asopa's procedure for repair of hypospadias is well established and suited for patient characteristics for which Snodgrass urethroplasty cannot be done. We describe our experience with this procedure in 30 patients managed with this procedure highlighting the factors affecting outcome in this repair. Data of 30 patients (age range 2.5-15 years) who underwent hypospadias repair in a tertiary care teaching institution from 2012 to 2015 with modified Asopa procedure (Hodgson XX technique) utilizing Transverse Preputial Island Flap by a single surgeon were reviewed and retrospectively analyzed according to age of patients, site of meatus, presence or absence or chordee, glans configuration and complications - fistula, glans dehiscence, meatal stenosis. These complications were further analyzed with respect to the various patient characteristics and GMS (Glans, Meatus and Shaft) score. The mean age of presentation was 5.5 years and mean follow-up period was 22 months. The mean total GMS score was 8.5; range being 11 to 5. In total, only six patients had complications (20%). The patients with low GMS score (7 or less) had no complications. The complication rate was more in proximal hypospadias repair (n= 5/24) when compared with distal hypospadias (n=1/6). There were more complications in patients with chordee (n=4/6) and those with conical glans (n=4/6). Location of the meatus, presence/absence of chordee and glans configuration affect outcome in patients undergoing modified Asopa's procedure for hypospadias repair.Keywords: hypospadias; Asopa's procedure; Child; Complications; Outcome.

Pediatric urolithiasis is a morbid condition that is often associated with underlying metabolic disorders. It is essential to diagnose and manage the underlying metabolic disorder along with management of urolithiasis to prevent stone recurrence and decrease the morbidity.
This retrospective observational study was conducted in 50 patients below 15 years of age with urolithiasis. Urine collection was done for 24 hours in toilet-trained children and spot samples were taken from younger children. The urinary parameters that were evaluated included calcium, oxalate, citrate, uric acid, and total urine volume. The serum levels of calcium, phosphorus, creatinine, uric acid, electrolytes, parathormone, and albumin were also measured. Stone analysis was done whenever possible.
There were 32 males and 18 females. Sixty-two percent of the patients had a low calcium intake and 70% of the children had a history of low water intake and had a low urine volume over 24 hours. Half of the children had serum metabolic abnormalities, including hypocalcaemia (n=19,38%), hypocalcaemia with hyperphosphatemia (n=2, 4%), hypercalcemia (n=2, 4%), and hyperuricemia (n=2,4%). Urinary abnormalities were detected in 42% of the children (n=21). These abnormalities included hypocitraturia in 11 patients (50%), hypercalciuria in 7 patients (30%), hyperoxaluria in 1 patient (6%), and hyperuricosuria in 2 patients (12%). Stone analysis was done in 18 patients. Fifteen patients (30%) had calcium oxalate stones, two patients (4%) had uric acid stones, and one patient had a mixed stone.
It is important to maintain an optimal blood calcium level and increase fluid intake to prevent stone formation in children.
