Introduction: We present our experience in image-guided percutaneous nephrolithotomy (PCNL) access in 591 patients. Materials and Methods: An IRB-approved review of all adult PCNL cases from 2009 to 2014 was performed. Patient data, information regarding stone size and location, procedural details, clinical success, complications by access site (upper pole versus middle or lower pole) and puncture location (supracostal versus infracostal) were recorded. Results: In this study, 591 patients (314 males, 278 females, mean stone size: 23 mm, range: 4-100 mm) were included. Stone clearance was achieved in 66% of patients. There were 174 total complications (29.3%). Upper pole access was less likely to require a secondary access to achieve stone clearance (p = 0.02) and was preferentially used for both larger stones (p = 0.006) and staghorn calculi (p = 0.001). If a supracostal approach to the upper pole was used, there were significantly more complications compared to an infracostal approach (p = 0.002). Conclusion: Upper pole access for PCNL provides anatomic advantages for stone clearance but significantly increases the risk for complications when a supracostal puncture is required.

Background:  Urolithiasis is a worldwide problem  due to its high prevalence and  recurrence. Percutaneous nephrolithotomy is a minimally invasive surgical option for the treatment of large renal stone burden greater than 20mm, staghorn calculi and lower pole calyceal stone greater than 10 mm. The objective of this study was to evaluate the safety and  efficacy of percutaneous nephrolithotomy in the management of lower pole calyceal stones.Methods: Seventy  patients who presented in between June 2013 and September 2017 with  lower pole calyceal stones and lower calyceal stones with pelvic extension  were included in the study. The  operating time, the hospital stay, complications rate, stone clearance rate were all noted. Patients were followed up in three and six weeks with X-ray KUB and ultrasonography of abdomen.Results: Seventy adult patients with lower pole calyceal stones underwent standard percutaneous nephrolithotomy. The mean age was 32 years (18-71 yrs). The mean stone size was 17.6 mm (15 –28 mm). The mean operating time was 62 minutes (48-124 mins) and hospital stay was 4.1 days(4-8 days). The stone clearance rate was 92.6% for stone <20mm and 90.7% stone size >20 mm. The complications noted were fever (8.5%), transient haematuria (20%), urine leak (5.7%), obstruction by residual fragments (5.7%) and one pseudoaneurysm(1.42%). Seven patients (10%) needed blood transfusion.Conclusions: Percutaneous nephrolithotomy is a safe, feasible and highly effective method for the treatment of lower pole calyceal stones.

A Prospective Study

Aims and Objective. “Postpercutaneous nephrolithotomy nephrostogram” (PPNN) is routinely performed in most of the centers. No published series could be found in the literature without post percutaneous nephrolithotomy nephrostogram. Hence, the aim of our study is to highlight that post percutaneous nephrolithotomy nephrostogram is not mandatory and it only adds to cost and morbidity without adding any information in the management of such patients.Methods. It was a prospective study from 2005 to 2012, conducted in our institute. It included 119 patients of renal stones who underwent percutaneous nephrolithotomy performed under the guidance of a single surgeon. Postoperative nephrostogram was not done in any of the patients.Results. Complete stone clearance was achieved in 97.5% of patients and 2.5% of patients needed two to three sessions of ESWL later on. None of the patients needed second look percutaneous nephrolithotomy or nephrostogram.Conclusion. Postpercutaneous nephrolithotomy nephrostogram increases chances of infection, inconvenience, contrast related complications, and cost, with no added advantage over plain X-ray KUB, and it should not be done as a routine investigation prior to the removal of PCN tube in patients with complete stone clearance.

Abstract Background The goal for using smaller caliber instruments in PNL was to reduce the access-related complications and to decrease morbidity. The objective of this study was to evaluate the safety and efficacy of Chinese minimally invasive percutaneous nephrolithotomy (MIPNL) in the treatment of renal stones ≤ 20 mm. Results Sixty-seven patients completed the study protocol. The mean age was 41.10 ± 13.99 years (range 18–68 years). There were 43 (64%) male and 24 (36%) females. The mean stone size was ranged from 78.5 to 439.6 mm2 (mean ± SD 172.48 ± 69.54 mm2). The overall SFR was (82%). Twelve (18%) needed post-MIPNL auxiliary procedure, in the form of second MIPNL in 3 (4.5%) cases, SWL in 7 (10%), and RIRS in 2 (3%) cases. The intraoperative complication was present in four patients (5%) include bleeding necessitate blood transfusion in one patient (1.5%) and renal collecting system perforation 3 (4.5%). The postoperative complication was urine leakage 5 (7.5) and fever in 6 (9%) of patients. Conclusion Chinese MIPNL is safe and effective method for treatment of renal stone ≤ 20 mm size with satisfactory SFR and low complication rate when SWL failed or contraindicated. It is considered a feasible treatment alternative to standard PNL, in the absence of flexible URS or miniature nephroscope.
