Abstract Content

Introduction

Access to upper calyx during PCNL is always considered difficult and risky due to increased risk of chest complications. We describe a new technique, named after Dr. R. K. Gopalakrishna, for renal descent for access to upper calyx, even in very high kidneys.

Materials and Methods

18G Chiba needle was used for renal displacement. After RGP, the needle was passed though the skin and muscle into peri renal fat (but not within renal parenchyma). It was used as a liver to pull the kidney down and then access was made to the upper calyx with another needle. A total of 42 patients, between 2021 and 2023, were undergone PCNL by Gopalakrishna technique of needle displacement of kidney for safe access to upper calyx. Kidney units with congenital anomalies, previous renal or retroperitoneal surgeries, fixed kidneys were excluded from the study.

Results

The overall stone clearance rate was 98%. Two patients had significant blood loss necessitating blood transfusion. Two patients developed plural effusion but improved on conservative treatment.

Conclusions

Renal displacement by Gopalakrishna technique is a simple, reproducible method for superior calyx access with relatively low complication rates.
