“…[23] Smaller caliber intruments seems to reduce blood loss in mPNL compared with sPNL. Cheng et al [24] found a 1.4% blood transfusion rate in their mPNL series. Similarly, Abdelhafez et al [25] demonstrated a 0.5% blood transfusion rate independent of stone size in 191 mPNL cases, which was remarkably lower than other sPNL series in the literature.…”

Objective: The aim of study was to compare the efficiency and safety of standard percutaneous nephrolithotomy (sPNL) and miniaturized percutaneous nephrolithotomy (mPNL) in lower calyx and/or pelvic stones smaller than three centimeters. Material and methods:From October 2010 to August 2015, 108 mPNL and 176 sPNL procedures were performed for renal stones smaller than three cm and located in the lower calyx and/or renal pelvis. All patients were evaluated preoperatively with intravenous pyelography and/or computed tomography. Intraoperative parameters, post-operative results and complications were recorded. Postoperative success was defined as complete stone clearance and/or clinically insignificant residual fragments at 3 rd month.Results: Preoperative characteristics were similar between sPNL and mPNL groups except previous renal stone operation history and gender. The mean operation time was significantly shorter in the sPNL group (p<0.001). The mean hemoglobin drop was significantly less in the mPNL group (p= 0.001), we found a 1.27±1.4 and 0.5±1.3 decrease in mean hemoglobin levels (mg/dL) in the sPNL and mPNL groups, respectively. Transfusion rate was 1.9% in mPNL and 5.6% in sPNL groups, and the difference was statistically significant (p=0.048). Only one patient in the sPNL group needed angiography and embolization. Postoperative JJ stent insertion rate was significantly higher in the mPNL group (p= 0.03). Conclusion:Both sPNL and mPNL are safe and effective surgical procedures for lower calyx and/or pelvis stones smaller than 3 cm. However, use of smaller caliber instruments was associated with a lesser hemoglobin drop and need for transfusion.

“…MPCNL is a modified version of PCNL that has been used extensively in China over the past two decades [15]. The popularity of MPCNL lies in its reported favorable procedural safety, however it has limited indications due to the small percutaneous tract (11-20F versus 26-34F) [13]. As such, MPCNL is primarily used in pediatric patients or adult patients with small stones or as a secondary technique used to supplement conventional PCNL [14].…”

Abstract. We examined the surgical outcomes of minimally invasive percutaneous nephrolithotomy (MPCNL) in complicating urolithiasis.10 patients were hospitalized for MPNCL due to upper tract urolithiasis. Calyx puncture was performed in the prone position under ultrasonographic guidance. The renal access route was established using a set of 8F-12F dilators, and a transpyelic ballistic lithotriptor was used to fragment calculi. The entire operative time was approximately 40-60 min, and the mean time of establishing percutaneous access was 20 min. The calculi were completely removed by single-session pneumatic lithotripsy. The 10 patients recovered from MPCNL uneventfully, and the follow-up radiological examinations identified no stone residual or recurrence.MPCNL is a minimally invasive modality that is effective and safe for the treatment of urolithiasis in patients.

“…The interest in reducing the tract size was to potentially reduce the invasiveness of the procedure and, therefore, attending complications. Three prospective comparative studies addressed the issues of efficacy and enhanced safety of reducing the tract size [6][7][8] .…”

Postoperative bleeding due to pseudoaneurysm formation is the major cause of percutaneous kidney interventions. Micro percutaneous nephrolithotomy is a one step procedure that used mostly lower pole stones. There are small series that reports technical feasibility and safety of microperc using the All-seeing needle. Here we state the first report of pseudoaneurysm and its treatment after microperc in the literature.
