Abstract
OBJECTIVE To evaluate and compare the outcome of ECIRS in the treatment of partial staghorn renal calculi in both prone split-leg positions versus GMSV positions with regard to; technical aspects, success rate, operative time, complications, safety, and effectiveness of both approaches. PATIENTS AND METHODS Between October 2018 and August 2021, 66 patients with partial staghorn calculi were enrolled in this prospective comparative study. Patients were randomly divided according to a 1:1 ratio into two groups. Group A included 33 patients who were treated by (ECIRS) in the prone split-leg position, and group B included 33 patients who were treated by (ECIRS) in the Galdakao-modified supine Valdivia (GMSV) position. RESULTS No significant statistical difference between both groups regarding the mean age (p = 0.448), mean body mass index (BMI) (p = 0.137), mean stone burden (p = 0.435), mean operative time (p = 0.541) and the number of calyces located in branched stones (p = 0.628). The mean hospital stay was 6.71 ± 1.12 days for group A and 6.66 ± 1.10 days for group B patients (p = 0.724). The final SFR was achieved in (29)87.87% and (30)90.9% of group A & B patients, respectively (p = 0.694). No significant difference was detected between both groups in perioperative complication rates. CONCLUSION ECIRS is safe and effective in treating partial staghorn calculi either in the prone split-leg position or in the Galdakao-modified supine Valdivia position, with comparable outcomes and no statistically significant difference between both positions.

Wang D, Sun H, Xie D, Liu Z, Yu D, Ding D. Application of a new position in endoscopic combined intrarenal surgery: modified prone split-leg position. BMC Urol 2022; 22:38. [PMID: 35305626 PMCID: PMC8934476 DOI: 10.1186/s12894-022-00994-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2021] [Accepted: 03/10/2022] [Indexed: 12/23/2022] Open
Abstract
Background Endoscopic combined intrarenal surgery (ECIRS) is well established as a minimally invasive procedure for the treatment of multiple urolithiasis. The position is the key to the perfect combination of percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS). Galdakao-modified supine Valdivia (GMSV) and prone split-leg positions are widely used. However, both positions have their own advantages and disadvantages. This study aimed to evaluate the effect of ECIRS in the treatment of multiple urolithiasis in the modified prone split-leg position. Patients and methods A total of 96 patients with multiple urolithiasis underwent ECIRS in modified prone split-leg position from September 2017 to January 2021. Relevant demographic and clinical data were analysed retrospectively. Clinical outcomes, such as the stone free rate, complications and postoperative hospital stay were evaluated. The chi-square test was used to compare categorical variables and Student’s t test was applied for continuous variables of the treatment groups. Results The mean renal stone size was 32.5 ± 10.7 mm and renal stone surface area was 712.2 ± 264.8 mm2. The mean ureteral stones size was 24.8 ± 12.3 mm. The mean surgical time was 82.2 ± 38.3 min. The incidence of complications was 16.7%, and they were mainly grade 1 and grade 2. No complications occurred above grade 3. The stone was completely removed in 75 (78.1%) patients in a single operation. The risk factors affecting the stone-free rate of ECIRS were analysed, and only the number of involved calyces by stone was found to be significant (p = 0.01). Conclusion ECIRS is safe and effective in the treatment of multiple renal calculi or multiple renal calculi with ipsilateral ureteral calculi in the modified prone split-leg position. The modification of the prone split-leg position makes the retrograde operation more convenient, which is conducive to the combination of RIRS and PCNL.

A prospective, randomized comparison of standard prone position versus flank-free modified supine position in percutaneous nephrolithotomy: A single-center initial experience. Urol Ann 2022; 14:172-176. [PMID: 35711483 PMCID: PMC9197000 DOI: 10.4103/ua.ua_31_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2020] [Accepted: 11/19/2020] [Indexed: 11/26/2022] Open
Abstract
Background: Percutaneous nephrolithotomy (PCNL) is the first choice for treatment of large renal stone >2 cm. The prone position is the classical position preferred by most surgeons. Aiming to improve patient anesthesia and surgery-related inconveniences of the prone position, Valdivia et al., 1987, described the performance of PCNL with the patient in the supine position. Hence, we aimed to study the safety and efficacy of flank-free modified supine position in PCNL compared to the standard prone position. Patients and Methods: This is a prospective randomized study for 60 patients with large renal stones planned for PCNL operation during the period from November 2017 to May 2019. Patients were divided into two groups (30 patients each group): Group A – patients underwent PCNL in the prone position and Group B – patients underwent PCNL in the modified flank supine position. Patients’ demographics, stone size, Hounsfield unit with intraoperative details as fluoroscopy time, operative time, and complications were recorded. Postoperatively, need for or not to blood transfusions, hospital stay, stone-free status, and postoperative complications were assessed. Results: There was no statistically significant difference between the prone and supine positions regarding stone size (4 cm vs. 4.5 cm, P = 0.16), Hounsfield unit (940 HU vs. 955 HU, P = 0.78), body mass index (31.2 kg/m2 vs. 32.5 kg/m2, P = 0.49), fluoroscopy time (6.9 min vs. 7.3 min, P = 0.5), operative time (89.5 min vs. 90.4 min, P = 0.9), residual stones (10% vs. 20%, P = 0.8), and hospital stay (45.6 h vs. 48.6 h, P = 0.5). Fever occurred in 3.3% of cases in each group and urine leakage observed in one patient with prone position. No blood transfusion was needed in both the groups. Conclusions: PCNL in the modified supine position proved to be a safe and effective choice compared to the prone position for adult patients with large renal calculi.

Abstract
Objective. To investigate the efficacy and safety of the oblique supine lithotomy during percutaneous nephrolithotomy (PCNL) to treat upper urinary calculi. Methods. Clinical data were retrospectively analyzed for 371 patients with upper urinary calculi who underwent PCNL at The First Affiliated Hospital of Guangzhou University of Chinese Medicine from January 2017 to October 2020. Based on different positions, patients were divided into the observation group (oblique supine lithotomy position, 155 cases, Group 1) or control group (prone position, 216 cases, Group 2). Groups were compared for effectiveness, complications, bleeding, surgical time, clinical indicators, and hospitalization time. Results. There were no significant differences in the clinical baseline data between the two groups (p > .05). However, the stone-free rate for patients was significantly higher in the observation than in the control group (p < .05). Both operation time and hospital stay time were significantly lower in the observation versus the control groups (p < .05). No significant differences were observed for complications or amount of blood loss (p > .05). Conclusion. In patients with upper urinary calculi, percutaneous nephrolithotomy in the oblique supine lithotomy position has a higher stone-free rate than the prone position. This approach can shorten the operation and provide better comfort and quicker recovery to the patients. A further advantage is that there is no difference in safety and blood loss between the prone position and the oblique lithotomy position.

Abstract
PURPOSE The percutaneous nephrolithotomy (PCNL) has become the gold-standard for treating patients with the larger renal stones and staghorn calculi. This study was designed to evaluate the outcomes of flank versus prone position in patients underwent ultrasonic-guided PCNL for treatment of large kidney stones. METHODS This prospective randomized clinical trial was conducted from September 2017 to September 2019 in the department of Urology, Labbafinejad University hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran. Two hundred patients with kidney stones larger than 2 cm underwent PCNLs in prone (n = 100) or flank position (n = 100). Success rate, operative time, access time, hemoglobin and creatinine changes, hospital stay, auxiliary procedure and surgical complications were compared between the two groups. RESULTS The two groups were similar in their baseline characteristics. The success rates in prone (87%) versus flank position (85%) were not significantly different at the first post-operative follow-up (p = 0.91). At the three-month follow-up, the overall stone free rates for the prone position PCNLs and flank position PCNLs were 94/100 (94%) and 90/100 (90%) (p = 0.96). There were no significant difference between the groups in operative time (p = 0.42), access time (p = 0.66), hemoglobin (p = 0.46) and creatinine (p = 0.22) changes, hospital stay (p = 0.05), auxiliary procedures (p = 0.75) and surgical complications. CONCLUSION Overall, there is no significant difference between prone and flank positions in success rate and complications. More prospective studies must be carried out to identify patient populations who are most apt to benefit from one position over the other.

Abstract
Introduction: Percutaneous nephrolithotomy (PCNL) is still the mainstay and the treatment of choice for most complex renal stones. The success of PCNL is defined by achieving a stone-free rate (SFR). Lower calyceal access PCNL is established to be the safest percutaneous access to the renal system, but controversy is present when it comes to SFR in comparison to upper calyceal and middle calyceal accesses. Aim: We aim to prove that lower calyceal access PCNL is the safest PCNL access and has the same efficacy as upper calyceal access PCNL for staghorn stones. Methodology: All lower calyceal access PCNLs done from May 2012 to August 2017 were included in the study. Postoperative complications were reported using the modified Clavien Grading System. Results: Sixty-seven patients were included in the study. The mean age was found to be 49.39 years; most (36 [53.73%]) patients were male. The prevalence of diabetes, hypertension, dyslipidemia, and chronic kidney disease was 40.91%, 47.76%, 37.31%, and 20.00%, respectively. The mean hospital stay was 7.9 days; mean operative time was 138.52 min. The mean staghorn stone burden was 476.34 mm2. About 80.59% (n = 54) of patients had complete stone resolution after the first session. Only 3 (4.47%) patients had complications and classified as Grade 2 on the modified Clavien Grading System and the remainder were classified as Grade 1, two patients needed postoperative blood transfusion, and one had a renal pelvis perforation. Conclusion: When it comes to safety and efficacy, the use of lower calyceal single-access PCNL has a very low complication rate compared to upper calyceal access PCNL, especially pneumothorax and bleeding.

Abstract
We report a case of a 45-year-old male who presented with recurrent left loin pain of three months' duration. A CT scan of his abdomen and pelvis showed a horseshoe kidney with two stones in the middle and lower calyx of the left kidney, each stone measuring approximately 1.5 cm in size. The patient had a past history of several unsuccessful attempts of extracorporeal shockwave lithotripsy (ESWL) on the same side. We treated the patient successfully by performing a percutaneous nephrolithotomy (PCNL) in the supine position that resulted in complete stone clearance. In addition, we report a shorter procedure time and hospital stay with no perioperative or post-operative complications.
