Factors Accountable for Unabated Obstruction Following Pyeloplasty.

Purpose: Split renal function (SFR) and frusemide washout (FWO) are assessed by the DTPA renogram to measure the renal parenchymal functions as well as the evidence of obstruction, both for diagnosis and to treat the pelviureteric junction obstruction. In good number of renal units, both these parameters remain unaltered even after surgery and cause anguish to parents and referring physicians and are usually attributed toward "defective pyeloplasty." In this study, we have tried to single out the bona fide responsible factor for the bad outcome; either the nonreversible kidney or the restenosis of pyeloplasty.

Advances in chemistry and composition of soft materials for drug releasing contact lenses.

Ocular drug delivery has always been a challenging feat to achieve in the field of medical sciences. One of the existing methods of non-invasive ocular drug delivery is the use of eye drops. However, drugs administered through these formulations have low bioavailability in the ocular system.

Vestibulo-Rectal Pull Through in H-Fistula in Girls.

Aims And Objectives: Vestibulo-rectal pull-through (VRPT) in H-fistula in girls was first described by Chatterjee . We are presenting our experience with this approach in 47 cases.

Materials And Methods: We have total 47 cases of which one is a recurrent fistula operated outside.

Regenerative urethroplasty in reoperative hypospadias: Buried strip principle revisited.

Aim: Reporting the feasibility of the Denis Browne (buried strip) principle along with tunica vaginalis (TV) pedicled wrapping of the strip in reoperative urethroplasty in hypospadias.

Materials And Methods: Over a period of 5 years, 32 patients presented with failure of previous urethroplasty and the range of failure was between 2 and 6 times; mean 2.5 times.

Novel bladder augmentation in a bilateral single system vaginal ectopia.

A 3-month-old girl presented with total urinary incontinence along with small bladder and bilateral single-system vaginal ectopic ureters [BSSVEU]. Bladder augmentation was done with dilated ureters (ureterocystoplasty) based on proximal blood supply of the ureters.

Ischiopagus tetrapus conjoined twins: 22 years after separation.

There is no record of both separated ischiopagus tetrapus conjoined twins leading normal lives 22 years after separation. We separated a pair of such twins in 1986 and have followed them up till date. Details regarding the technique of separation and the procedures required to ensure normal defecation and micturition and normal musculoskeletal function have been described by us in earlier communications.

Rectourinary perineal fistula--a unique anomaly.

Two patients who presented with a unique anorectal malformation are described. They had what we have named rectourinary perineal fistula. The first patient had a more severe malformation, rectovesicoperineal fistula, and has been followed up for 28 years.

Preliminary report on the International Conference for the Development of Standards for the Treatment of Anorectal Malformations.

Background: Anorectal malformations (ARM) are common congenital anomalies seen throughout the world. Comparison of outcome data has been hindered because of confusion related to classification and assessment systems.

Methods: The goals of the Krinkenbeck Conference on ARM was to develop standards for an International Classification of ARM based on a modification of fistula type and adding rare and regional variants, and design a system for comparable follow up studies.

Lipoblastomatosis--a case report.

Lipoblastoma and lipoblastomatosis are benign fatty tumors of soft tissues that are unique to childhood. A male infant aged 5 months presented with a history of recurrent lump in the left scapular region. He had been operated upon for the same lump 2 months earlier.

Perineal groove with penoscrotal hypospadias.

We describe a boy who presented with penoscrotal hypospadias with bifid scrotum as well as a perineal groove. The operative procedures carried out have been delineated and the reasons for our reporting this case are explained.
