Objective: We aimed to compare outcomes of percutaneous nephrolithotomy (PNL) surgery in patients who had and had not undergone renal stone surgery before PNL. Material and Methods: We retrospectively analyzed the medical records of all patients who underwent PNL in our department between 2010 and 2019. Examined parameters consisted of patient demographics, medical and surgical history, stone size, stone density, stone site, estimated intraoperative blood loss, duration of operation, hospital stay and stone-free status. Results: A total of 193 patients were included the study. The mean age of the patients was 45±13 years. The mean duration of surgery was 69±11.5 minutes. The mean stone area was 720.2±600.4 mm2 and the mean stone attenuation was 982.8±327.7 HU. The mean postoperative hemoglobin decrease was 1.8±1.3 g/dL. 66 patients had previous stone surgery including open stone surgery, PNL and retrograde intrarenal surgery (RIRS). There was no statistically significant difference between patients who had and had not previousşy undergone renal stone surgery in terms of age, gender, body mass index and stone area. Operative time, estimated intraoperative blood loss, postoperative hemoglobin decreases and hospital stay were comparable between patients who had, and hed not undergone previous renal stone surgery. Stone-free rate was significantly higher in primary PNL patients compared to patients with a history of renal stone surgery (92.1% vs 77.3%, p=0.006). Conclusion: PNL has a similar complication rate in patients with and without previous kidney stone surgery. However, achieving stone-free status may be challenging in patients with a history of ipsilateral renal stone surgery.

Objectives: Percutaneous nephrolithotomy on staghorn calculi is challenging for urologists because it is difficult to remove all of the stones. The purpose of this study was to evaluate the associated factors of stone-free rate after primary percutaneous nephrolithotomy on staghorn calculi in a large series of patients at a single, tertiary referral, endourologic stone center. Methods: We collected data from medical record between January 2000 and December 2015. A total of 345 primary percutaneous nephrolithotomy procedures were performed for patients with staghorn calculi. This study included both and made no distinction between partial and complete staghorn calculi. Stone-free is defined as the absence of residual stones after undergoing percutaneous nephrolithotomy for the first time. Significant factors from univariate analysis that correlated with stone-free rate after primary percutaneous nephrolithotomy of staghorn stone were further analyzed using multivariate regression analysis. Results: The mean patient age was 52.23±10.38 years. The stone-free rate of percutaneous nephrolithotomy monotherapy was 62.6%. The mean operating time was 79.55±34.46 minutes. The mean length of stay in hospital was 4.29±3.00 days. Using the chi-square test, history of ipsilateral open renal stone surgery (p = 0.01), stone burden (p = < 0.001), and type of anesthesia (p = 0.04) had a significant impact on the stone-free. From multivariate analysis, the history of ipsilateral open renal stone surgery [OR 0.48; 95% CI 0.28-0.81; p 0.01] and the stone burden [OR 0.28; 95% CI 0.18-0.45; p 0.00] were significant independent risk factors for stone-free.

<p><strong>Introduction:</strong> Our aim was to demonstrate the effect of insicion of renal parenchyma during open renal stone surgery (ORSS) on percutaneous nephrolithotomy (PNL) outcomes.</p><p><strong>Methods:</strong> Patients with history of ORSS who underwent PNL operation between June 2005 and June 2015 were analyzed retrospectively. Patients were divided into two groups according to their type of previous ORSS. Patients who had a history of ORSS with parenchymal insicion, such as radial nephrotomies, anatrophic nephrolithotomy, lower pole resection, and partial nephrectomy, were included in Group 1. Other patients with a history of open pyelolithotomy were enrolled in Group 2. Preoperative characteristics, perioperative data, stone-free status, and complications were compared between the groups. Stone-free status was defined as complete clearance of stone(s) or presence of residual fragments smaller than 4 mm. The retrospective nature of our study, different experience level of surgeons, and lack of the evaluation of anesthetic agents and cost of procedures were limitations of our study.</p><p><strong>Results:</strong> 123 and 111 patients were enrolled in Groups 1 and 2, respectively. Preoperative characteristics were similar between groups. In Group 1, the mean operative time was statistically longer than in Group 2 (p=0.013). Stone-free status was significantly higher in Group 2 than in Group 1 (p=0.027). Complication rates were similar between groups. Hemorrhage requiring blood transfusion was the most common complication in both groups (10.5% vs. 9.9%).</p><p><strong>Conclusions:</strong> Our study demonstrated that a history of previous ORSS with parenchymal insicion significantly reduces the success rates of PNL procedure.</p>

Objectives: To compare perioperative and oncological outcomes between open and laparoscopic radical cystectomy in a single-centre setting. Materials and methods: This study was a retrospective cohort (level 2b evidence) non-randomised review of 228 radical cystectomies that were performed between January 2010 and February 2016. Primary outcome measures were operative time, complications, blood loss and length of hospital stay. Statistical analysis was performed using the SPSS v21.0. Quantitative values were compared with Student’s t-test; categorical variables with the chi-square test. Statistical significance was considered a result of an alpha value less than 0.05. A Kaplan–Meier survival analysis was also conducted. Results: Intraoperative blood loss was lower in laparoscopic surgery (855±673 vs. 716±570 mL, P=0.15), which had a significant impact on transfusion rates ( P=0.02). Operative times were lower in open surgery (339±52.9 vs. 353.1±67.1 minutes, P=0.10), while hospital stay was lower in the laparoscopic group (14.2±11.2 vs. 16.0±13.6 days, P=0.28). Five-year survival rates were superior for patients who underwent an open procedure but were not statistically significant ( P=0.10). Conclusion: This is, so far, the largest cohort to compare laparoscopic and open radical cystectomy. The laparoscopic approach can reduce the need for transfusion; however, there was no statistically significant difference in complication rates, duration of surgery, length of hospital stay or intraoperative blood loss, survival and margin positivity. Level of evidence: Not applicable for this multicentre audit.

Background: Nephrolithiais is a recurrent disease. Recent advances have enabled stone surgeries to be performed by minimal invasive techniques; but still a large number of patients present with history of ipsilateral open renal stone surgery. Previous scar to the kidney and overlying muscles are fraught with possibility of increased complications. This study was conducted to evaluate the perioperative results of percutaneous nephrolithotomy in patients with a history of open stone surgery and to compare with those undergoing percutaneous nephrolithotomy for the first time.Methods: A retrospective study of all the percutaneous nephrolithotomy performed by standard technique within four years at Bir Hospital was made. Patients were divided into those undergoing percutaneous nephrolithotomy for the first time and those who had undergone open renal stone surgery in the past. Preoperative and intraoperative variables were recorded and postoperative stone free status and complications were evaluated. Results: Six hundred and twenty seven patients; out of 691, who had undergone percutaneous nephrolithotomy were included. Demographic variables and stone characteristics were similar in the two study groups. percutaneous nephrolithotomy was found to be statistically similar in the two groups in terms of the number of tracts made (p= 0.1642) and operative time (0.9197). Exit strategies were similar in both groups. Stone free rate was 83.33% in patients undergoing percutaneous nephrolithotomy for first time and 82.08% in those with history of open surgery. Average hospital stay was 3 days in both groups. Although the group with history of previous surgery had significantly more complications (p= 0.0207), Clavien grading was similar in the two groups.Conclusions: This study shows that the rate of complications is more in patients with history of open surgery, most complications are minor, not requiring intensive management. percutaneous nephrolithotomy is efficient and safe in patients with history of open renal stone surgery.

Introduction: Tonsillectomy is frequently performed surgical procedure. There are several different methods with varied advantages and disadvantages. In spite of the different techniques available there is no consensus and definite evidence for best method. The most commonly performed are conventional dissection and bipolar electrocauterization methods. Aims: The aim of the study was to compare time required for the completion of surgery, intraoperative and postoperative blood loss along with post operative pain between conventional dissection and bipolar electrocauterization methods. Methods: This comparative study was conducted from August 2019 to March 2021 in total of 30 patients planned for tonsillectomy in department of Otorhinolaryngology, Nepalgunj Medical College Teaching Hospital.In every patient right side tonsillectomy was done with conventional dissection method and left side tonsillectomy was done with bipolar electrocauterization method. Results: The mean age was 27.2±13.08 years. The mean duration of surgery was 16.53 ± 2.43 min and 11.10 ± 1.93 min in conventional dissection method and bipolar electrocauterization method respectively. The difference was statistically significant. Intraoperative blood loss was significantly lower in bipolar electrocauterization method with mean intraoperative blood loss of 19 ±4.62 ml in bipolar electrocauterization group and 81.83 ±36.54 ml in conventional dissection method. The pain intensity was statistically similar in both methods at all-time intervals post operatively. Conclusion: In tonsillectomy, bipolar electrocauterization method has advantage over conventional dissection method in regards to reduced surgical time and intra operative blood loss, without any significant difference in post-operative pain intensity and post-operative hemorrhage.

Abstract We aim to evaluate the surgical outcome of laparoendoscopic two-site myomectomy (LETS-M). The medical records of 204 women receiving LETS-M in a tertiary referral center, including 183 surgeries performed by the experienced surgeon and 21 surgeries performed by 3 well-supervised trainees were retrospectively reviewed. The age of the participants was 39.3±6.4 years. The mean diameter of the largest myoma was 8.5±2.2 cm. The mean weight of the myomas was 281.1±183.1 g. The operation time was 97.6±40.2 min, and the intraoperative blood loss was 99.3±115.2 mL. There were 3 (1%) cases of excessive blood loss (more than 500 mL) and 2 (1%) of postoperative hematoma. The only significant difference between the experienced surgeon and trainees was the operation time (92.3±32.2 min vs. 141.2±54 min, p<.001), while the myoma number, myoma diameter, myoma weight, and intraoperative blood loss were not significantly different. The operation time did not differ among different myoma locations. In multivariate analysis, virginity, myoma number, more than 2 large myomas, and myoma size were independent variables for longer operation times. No patient experienced any major complications. The result revealed that LETS-M is a minimally invasive surgical method that is safe, effective, and easy to learn for managing uterine myoma.

Background: We aimed to compare the Guy’s stone score and STONE nephrolithometry score and assess their predictive accuracy for percutaneous nephrolithotomy (PCNL) outcomes.  Methods: A total of 100 patients, who underwent PCNL between Jan 2018 and Dec 2018 were included in the study. All patients were evaluated with computerized tomography (CT) scan preoperatively and scores were calculated. Patient demographic characteristics, intraoperative and postoperative variable were evaluated. The relationship between the Guy’s and STONE scores, and their prediction for postoperative stone-free status, complications were compared. Results: The mean Guy’s score was 2.04±1.01, and the mean STONE score was 8.0+1.7. The mean operative time was 101.9+41 minutes and the mean blood loss was 170+113ml. The complication rate in our study was found to be 32%, majority were grade 1-2. Both scoring systems showed positive correlation with stone burden, operating time and blood loss. The overall stone free rate was 72% and both the GSS and STONE score were significantly associated with success of the procedure.  Conclusions: Both Guy’s and STONE scoring systems are equally effective in predicting stone-free status.

Introduction: Robotic-assisted simple prostatectomy (RASP) has been touted as an alternative to open simple prostatectomy (OSP) to treat large gland benign prostatic hyperplasia. Our study assesses our institution’s experience with RASP and reviews the literature.Methods: We performed a retrospective chart review from January 2011 to November 2013 of all patients undergoing RASP and OSP. Operative and 90-day outcomes, including operation time, intraoperative blood loss, length of hospital stay (LOS), transfusion requirements, and complication rates, were assessed.Results: Thirty-two patients were identified: 4 undergoing RASP and 28 undergoing OSP. There was no difference in mean age at surgery (69.3 vs. 75.2 years; p = 0.17), mean Charlson Comorbidity Index (2.5 vs. 3.5; p = 0.19), and mean prostate volume on TRUS (239 vs. 180 mL; p = 0.09) in the robotic and open groups, respectively. There was a significant difference in the mean length of operation, with RASP exceeding OSP (161 vs. 79 min; p = 0.008). The mean intraoperative blood loss was significantly higher in the open group (835.7 vs. 218.8 mL; p = 0.0001). Mean LOS was shorter in the RASP group (2.3 vs. 5.5 days; p = 0.0001). No significant differences were noted in the 90-day transfusion rate (p = 0.13), or overall complication rate at 0% with RASP vs. 57.1% with OSP (p = 0.10).Conclusions: Our data suggest RASP has a shorter LOS and lower intraoperative volume of blood loss, with the disadvantage of a longer operating time, compared to OSP. It is a feasible technique and deserves further investigation and consideration at Canadian centres performing robotic prostatectomies.

Abstract Background Video-assisted thoracoscopic surgery (VATS) has become the preferred approach for minimizing harm from thoracic operations. There is no report, however, which has discussed the feasibility of VATS in ipsilateral reoperation of major lung resection. Methods The present study included patients who had undergone ipsilateral reoperation of major lung resection by VATS from October 2009 to May 2017. Referring clinical data were recruited for analysis. Results Fourteen patients were recruited in the present study, including nine patients who underwent lobectomy and five who underwent segmentectomy during the second operation. Different hila were found in 6 patients, and pleural adhesions appeared in 10 patients. The average intraoperative blood loss was 203.6 ± 121.7 mL, and the mean operating room time was 2.2 ± 0.5 hours. There were no intraoperative deaths, and only one patient required conversion to thoracotomy. The average drainage time was 5.9 ± 4.6, and the mean hospital stay was 6.7 ± 4.2 days. Conclusion Though it is technically demanding to safely handle the changed hilum structure caused by the last operation, major lung resection by VATS is feasible for ipsilateral reoperation in appropriate candidates.
