Background: Percutaneous nephrolithotomy (PCNL) is a
procedure to remove stones from the kidney. Intra-operative bleeding is one of
the known complications in previously operated cases. Hemoglobin drop during
PCNL with or without history of prior open renal surgery may differ so we
conducted this study.
Aim: To determine the mean drop in hemoglobin in
patients undergoing PCNL and mean hemoglobin in previously operated versus new
cases undergoing PCNL.
Methods: This descriptive cross sectional study was done
at Armed Forces Institute of Urology Rawalpindi from 20-03-2015 to 20-09-2015.
A total of 90 patients were selected. Non-probability purposive sampling
technique was used. Blood samples taken on 1st day and 24 hours post
operatively. Drop in hemoglobin was calculated.
Results: The mean age of patients was 43.68±13.14
years and male to female ratio was 2.2:1. Mean size of stone 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. The significant distinction was present between the
falls in Hb values.
Conclusion: It is concluded that statistically
significant more drop in the Hb values in previously operated cases as compared
to new cases.
