“…Patients with obesity may present various technical challenges, such as with anesthesia, patient positioning, proper radiological visualization of the stone, increased skin-to-collecting-system distance, the need for extra-long devices, and nephrostomy-tube dislodgement. Despite all these problems, similar stone-free and complication rates were reported with PNL among patients with and without obesity in single-center studies [6][7][8]10]. Consistent with these studies, no relationship was found between obesity and operative success rates in the present study, and our results indicate that PNL outcome is independent of BMI.…”

“…In a meta-analysis of 4.962 patients, however, Zhou et al [6] reported no significant difference in operative time between patients with and without obesity, although it was significantly longer in patients with super-obesity (>40 kg/ m 2 ). No statistically significant association was observed between obesity and operative time in studies with a similar design to that of the present study [7,8,11].…”

“…Successful PNL depends on both patient-and stone-related factors, such as a stone's size, location, and composition, pelvicalyceal anatomy, surgical experience, and previous urological procedures [5]. Studies investigating the effects of obesity on PNL outcomes have reported similar feasibility, safety, efficacy, and stone-free and complication rates in patients with and without obesity, and have concluded that PNL can safely be used with patients with obesity [6][7][8]. Although several previous studies have investigated the effects of obesity on PNL, the number investigating its effect on PNL outcomes in detail (such as its effect on residual stone size) is very small.…”

Purpose: To assess the safety and effectiveness of percutaneous nephrolithotomy (PCNL) in patients with obesity.Materials and methods: The records of patients who underwent conventional PCNL were retrospectively evaluated using our database in Department of Urology, Gazi Hospital, Samsun, Turkey, from January 2015 to January 2020. Patients were divided into four groups based on body-mass index (BMI) range <25 (Group 1), 25-29.9 (Group 2), 30-34.9 (Group 3), and ≥35 kg/m2 (Group 4). Baseline characteristics, outcomes, and complications were then compared between the groups. Achieving stone-free status or a residual-stone size of ≤4 mm was regarded as an operational success.Results: A total of 462 patients, 121 (26.2%) in Group 1, 159 (34.4%) in Group 2, 133 (28.8%) in Group 3, and 49 (10.6%) in Group 4, were enrolled in the study. No significant difference was determined in terms of operative time, access number, hemoglobin drop, hospital stay, and success/complication rates. Residual-stone area increased in line with BMI. However, this increase in residual-stone area was only statistically significant in Group 1 and Group 4 (p=0.009). The overall stone clearance rate was 81.8%, and the complication rate requiring invasive procedures was 16.4%.Conclusion: Our study revealed that obesity does not affect the outcomes of PCNL without residual-stone size.

“…Thirdly, there are limitations of the length of the nephroscope and instruments. [22][23][24] However, there are some tricks for tackling these issues such as the choice of the shorter length of the access track to allow ease of instrument maneuverability during the procedure. Furthermore, extra-long custom-trimmed access sheaths may help in gaining proper access tract.…”

Background and Objectives: Urolithiasis is prevalent globally. Over time, innovation in endoscopic instruments and miniaturization has untangled the interventional strategy for carrying out remedial surgical procedures for renal stones. However, studies have been scarce as for sequelae of Percutaneous Nephrolithotomy (PCNL) in varying body mass index group patients in the developing world. We aimed to report success rates and complications in different BMI groups. Methods: This was a retrospective study wherein data of 359 patients was reviewed in charts. These patients went through PCNL at our department from July 2011 till September 2019. Three groups of patients were made in agreement with WHO BMI classification. Information concerning study variables was noted in designated and then processed in SPSS version 16 for the statistical computations. Results: On the whole, the mean age of patients was 44.6± 14.4 years. While the mean calculus size was 3.1± 1.4 cm. Moreover, the majority of stones in all the three groups belonged to Guy’s stone score 1 and 2 (see Table-I). The overall mean procedure time and inpatient stay were almost comparable in the obese group. The highest stone-free rate was observed in the normal weight group (77.69 %), however, stone-free status in overweight and obese groups was not comparatively too lower (p=0.74). Complication rates were being close among the three groups. Conclusion: PCNL can be ventured with safety and in an effectual manner for attaining stone treatment goals alike in obese and non-obese group patients. doi: https://doi.org/10.12669/pjms.38.8.3663 How to cite this:Iqbal N, Hasan A, Razzaq S, Rashid FS.

“…Today, percutaneous nephrolithotomy (PNL) is the gold standard minimally invasive treatment method in the treatment of renal stones larger than 2 cm. 1 The success rates of PNL procedure have increased with technological advances and increased surgical experience. Abnormal enlargement of the kidney pelvis and calyces is defined as hydronephrosis.…”

Objective: To investigate the effect of the presence of severe hydronephrosis on percutaneous nephrolithotomy (PNL) outcome in patients who underwent PNL operation with one-shot dilatation technique. Materials and methods: Medical data of 989 patients underwent PNL operation in our clinic between 2012 and 2018 were retrospectively reviewed. We included 373 of the patients underwent PNL operation due to renal pelvic stone, who were older than 18 years of age, who did not have any urinary tract abnormality, and had no previous history of open renal stone operation. Patients were divided into two groups according to the presence of severe hydronephrosis and absence of hydronephrosis. These two groups were compared in terms of age, gender, body mass index (BMI), number of stones, stone burden, operation duration, fluoroscopy time, hospitalization time, hemoglobin and creatinine change, complications, and stone free rate. Results: There was no statistically significant difference between the groups in terms of age, gender, BMI, stone number, stone size, stone density, operation duration, fluoroscopy time, and hospitalization duration. The mean change in hemoglobin was 1.5 g/dL in group 1 and 1.1 g/dL in group 2. This difference was statistically significant ( p = 0.006). Postoperative blood transfusion was required for 3 patients (2.1%) in group 1 and 12 patients (5.1%) in group 2. This difference was statistically significant ( p < 0.001). Conclusion: Only the presence of severe hydronephrosis was found to be associated with the change in hemoglobin and postoperative blood transfusion.
