Allograft lithiasis is usually secondary. Donor-graft lithiasis is a rare cause and only 5 cases have been reported. We report 2 such cases which are the first in the live-related transplantation programme. The pressing need to increase the donor pool in developing countries, safety of therapy in graft lithiasis coupled with minimal estimated risk of lithiasis recurrence in the donor are the main justifications for accepting calculi bearing kidney for transplantation. The 2 cases underwent extracorporeal Shockwave lithotripsy using the overhead table module of the Lithostar Plus. The technical ease of lithotripsy using an on-line ultrasound module in these ‘ectopically’ placed kidneys is discussed. The effect of Shockwaves on allograft function was studied by a pre- and postrenal scan (99Tc-DTPA) and serum creatinine. No adverse effect of Shockwave on allograft function was noted both on short- and long-term follow-up.
We report 2 cases of percutaneous drainage and alcohol instillation of renal hydatid cysts. The feasibility of percutaneous management of renal hydatidosis, emphasizing its safety, efficacy and obvious advantages, is discussed.
In 1980 Mitrofanoff described a method to achieve continent urinary diversion by surgically closing the bladder neck and creating a continent catheterizable stoma from the appendix which had been implanted in a nonrefluxing manner into the bladder or from a nonrefluxing distal ureter. The Mitrofanoff principle (MP) serves well as a continence mechanism for either the native bladder or intestinal reservoirs. We review 17 patients, including 10 children, who were treated with the MP and received a continent catheterizable channel. For the MP, appendix was used in 16 patients and ureter in 1. The continuity between the urinary reservoir and urethra was maintained wherever possible. Bladder neck suspension was preferred to bladder neck closure in incontinent females and boys. Complications and their management have been discussed at length. Stable renal functions, ease of catheterization and urinary continence were achieved in 93.8% of the patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
