For renal stone, miniPCNL was new treatment choice. The miniature nephroscopy offers a very slim, extremely easy-to-urs instrument for therapy of renal-pelvis and caliceal stone. It provides minimum renal trauma during PCNL. Here we present our initial experience in minPCNL.
Materials and Methods:
A total of 40 patients (male: female=27:13) underwent mini-PCNL since 2016. Stone location (left: right=21:19) were renal pelvis with obstruction. Mean age was 57±9. Mean stone burden was 2.5±0.7 cm. Stone burden more than 2.5 cm was 15 cases. Two stage PCNL was done. Wolf miniPCNL instrument (14.5F outer sheath, 6Fr working channel) was used. For lithotripsy, A 30W Ho-Yag Laser was used. Stone was removed along 16~18Fr Amplatz sheath with water flow and forceps.
Mean operative times were 100±52 minutes. No serious complication was noted post operation. Blood loss was minimum.  No patient received blood transfusion.  Mean hospital stay was 4.3±0.9 days. Stone treatment had shift from traditional PCNL to miniPCNL after more experience on stone management and removal.
MiniPCNL technique needs few learning curves. It provided few trauma to kidney and minimum blood loss during operation. Operative time is longer comparing with traditional PCNL using ultrasound. But post-operative recovery was rapid than PCNL. For moderate stone burden within renal pelvis, miniPCNL was a good treatment choice.
