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.
Keywwords: Percutaneous
