Percutaneous nephrolithotomy (PCNL)is generally a very
safe and well-tolerated procedure, but as with any surgical intervention, PCNL
is not free of complications. It was very difficult to compare complications of
PCNL with other hospitals data until the development of calvin grading system.
Place and duration
of study: This study
was conducted in Urology Department at Shaikh Zayed Hospital, Lahore from
January 2017 to January 2018.
Methods: A total 190 cases of PCNL
procedures were performed and complications were noted. Clavien grading system provides classification of complications of PCNL
according to their severity in an excellent way.
Results: Out of
the 190 patients, 130(68%) were male and 60(32%) female. The mean age of the
patient population was 35.0±9.56 years (range: 10–65 years). The mean size of
stones was 2.8cm (ranging from 1.5-4cm). 70(37%) patients had pelvic stones, 30(16%)
patients had stag horn calculi, 40(21%) patients had upper pole calyces stones
and 50(26%) patients had lower pole calyces stones.
Conclusion: Percutaneous nephrolithotomy is a
gold standard treatment for renal stone disease. It is
need of time to document complications of other urological procedures according
to Calvin grading system so that outcomes of other urological procedures may
