mPNL is alternative to
standard PNL for medium
renal stones, with better
morbidity profile. However
there is no comparison group.

umPNL safe and efficacious
alternative for small-volume
disease with advantage of
high ISFR and final SFR and
lower complication rates.
Indications for umPNL are
moderate-sized stones as
alternative to ESWL or RIRS,
low pole stones not amenable
to RIRS, diverticular renal
stones, and stones refractory
to ESWL

Total SFR greater for small
stones. Most patients could be
rendered stone-free with
1 auxiliary procedure. The
high success rate and low rate
of higher grade complications
justify mPNL for large stones
