ABSTRACT

 

Background: Percutaneous nephrolithotomy (PCNL) is a minimally invasive procedure for removal of kidney stones. Intra-operative bleeding is one of the known complications, especially in previously operated cases. Haemoglobin fall during PCNL with or without a history of prior open renal surgery may differ so we conducted this study.

Aim: To determine the mean drop in haemoglobin in previously operated versus new cases undergoing PCNL.

Methods: This descriptive cross sectional study was carried out in Armed Forces Institute of Urology Rawalpindi from March 2015 to September 2015. A total of 90 patients were selected after taking permission from hospital ethical committee. Non-probability purposive sampling technique was used. Blood samples were taken on 1st day and 24 hours postoperatively to determine haemoglobin levels. Drop-in haemoglobin was calculated.

Results: The mean age was 43.68±13.14 years and ratio of male to female patients was 2.2:1. Mean stone size was 2.54±0.62cm and overall mean fall in Hb was 1.05±0.45mg/dl. 31.11% of the cases were previously operated while 68.89% were new cases. The mean fall in Hb value in previously operated cases was 1.23±0.31mg/dl and mean fall in Hb value in new cases was 0.97±0.49mg/dl which was statistically significant.

Conclusion: It is concluded that statistically significant more drop in the Hb values in previously operated cases as compared to new cases.
