RESUMEN
Transcutaneous nephrolithotomy is widely used in management of nephrolithiasis. The outcome of the intervention is largely due to successful establishment of nephrostoma. For this purpose retrograde nephrostomy was employed in 7 nephrolithiasis patients. Relevant technique is described for primary and recurrent disease. Its indications involve absence of calyceal-pelvic dilation, obesity, pararenal cicatrices. The manipulation appeared beneficial in all the cases. Retrograde nephrostomy is considered an alternative to antegrade nephrostomy in the treatment of nephrolithiasis.
