“…ESWL is preferred for the lithotripsy of renal calculi between 4 mm and 20 mm in diameter, and is less successful for the fragmented ureteral stones [12]. 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]. Advancements in MPCNL equipment and techniques have helped broaden the indication of MPCNL to any UTUL requiring PCNL intervention, as suggested by Guangzhou and colleagues [15]. Using multiple tracts, MPCNL allows for the removal of staghorn calculi or complex renal calculi [16].…”

“…Like any other MIS technique, MPCNL requires the operators to have a good knowledge of local anatomy. The appropriate puncture into the collecting system is the most crucial for a successful MPCNL and greatest risk occurs during the percutaneous manipulation [15]. It is technically challenging to establish the nephrolithotomy access in scoliotic patients, especially in those with a larger lateral spinal curvature.…”

“…Despite MPCNL's minimally invasive advantages, it is subject to some complications [15] .The primary complications of MPCNL consist of visceral injury, renal vascular injury, urinary tract perforation/leakage, urosepsis, and hydrothorax caused by the percutaneous puncture at the 11th intercostal space. As reported by Kara et al, [9] the most common and serious complication following PCNL is renal hemorrhage, which requires blood transfusions in severe cases.…”

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.

“…Access to the collecting system is performed via upper, middle and lower calices. [11][12][13][14][15] Upper calyx access provides a perfect reach to the collecting system and many upper tract stones. However, this access may incur intrathoracic complications.…”

Background: Middle calyx access has been underused in percutaneous nephrolithotomy (PCNL), especially in the supine position. We compared the safety and efficacy outcomes between middle calyx and lower calyx accesses in the complete supine PCNL in a non-randomized single-surgeon clinical study. Methods: Between February 2008 and October 2011, 170 patients underwent posterior subcostal single tract complete supine PCNL with one-shot dilation and middle calyx (n = 48) and lower calyx (n = 122) accesses. Stone location and surgeon decision determined target calyx for access. Inclusion criteria were pelvis stones, staghorn stones and multiple location stones. Exclusion criteria were renal anomalies, only upper calyx stones, only middle calyx stones and only lower calyx stones. Important parameters were compared between the two groups. A p value of <0.05 was considered significant. Results: Two groups were similar in important patient-and stonerelated parameters. Mean operative time (60.7 minutes), mean postoperative hospital stay (1.84 days) and mean hemoglobin drop (0.67 g/dL) in the middle calyx group were significantly lesser than in the lower calyx group (80.1 minutes, 2.19 days, 1.36 g/dL). The middle calyx group (89.6%; 79.6%) had a higher stone-free rate (p = 0.054) and efficiency quotient than the lower calyx group (76.2%; 61.6%). In the middle calyx group (10.4%; 2.1%), complication and transfusion rates were lesser (p > 0.05) than lower calyx group (14.8%; 7.4%). No significant difference (p = 0.40) was seen between two groups using the modified Clavien classification of complications. Interpretation: Middle calyx can be an optimal access in PCNL with the complete supine position for many of upper urinary tract stones due to its superior outcomes.
