Abstract Background: Endoscopic combined intrarenal surgery (ECIRS) well established as a minimally invasive procedure for is 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 position are widely used. However, both positions have their own advantages and disadvantages. This study aimed at evaluating the effect of ECIRS in the treatment of multiple urolithiasis in the modified prone split-leg position.Patients and methods: Total 96 patients with multiple urolithiasis underwent ECIRS in modified prone split-leg position from September 2017 and January 2021. Relevant demographic and clinical data were analysed retrospectively. Clinical outcomes such as stone free rate, complications and postoperative hospital stay were evaluated. Factors predicting stone free rate were also evaluated. Chi-square test was used to compare categorical variables and Student t test was applied for continuous variables of the treatment groups.Results: The mean renal stones 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%, 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 analyzed, 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 modified of prone split-leg position makes the retrograde operation more convenient, which is conducive to the combination of RIRS and PCNL.

Summary Objective: To analyze the results of flexible ureterorenoscopy (F-URS) with holmium laser in the treatment of kidney stones with ectopic and fusion anomalies (horseshoe kidney and rotation anomalies). Method: We reviewed data from 13 patients with fusion and ectopic renal anomalies that underwent F-URS from April 2011 to April 2017. We analyzed demographic and clinical data (age, gender, BMI, anatomical abnormality, location and dimension of the renal calculi) and perioperative data (method of treatment, stone-free rate, number of days with DJ catheter and perioperative complications). Results: The mean stone size was 12.23 +/- 5.43 mm (range 6-22mm), located in the inferior (58.33%) and middle (16.76%) calyceal units, renal pelvis (16.67%) and multiple locations (8.33%). All 13 patients were treated with Ho-Yag laser, using dusting technique (25%), fragmentation and extraction of the calculi (58.33%) and mixed technique (16.67%). We did not have any severe perioperative complication. After 90 days, nine patients (75%) were considered stone free. Conclusion: Our data suggest that F-URS is a safe and feasible choice for the treatment of kidney stones in patients with renal ectopic and fusion anomalies.

Objective.Treatment options for urolithiasis in children include URSL and RIRS. Various types of energy are used in the disintegration of deposits in these procedures. We decided to evaluate the usefulness of URSL and RIRS techniques and compare the effectiveness of pneumatic lithotripters and holmium lasers in the child population based on our experience.Materials and Methods.One hundred eight (108) children who underwent URSL and RIRS procedures were enrolled in the study and divided into two (2) groups according to the type of energy used: pneumatic lithotripter versus holmium laser. We evaluated the procedures’ duration and effectiveness according to the stone-free rate (SFR) directly after the procedure and after fourteen (14) days and the rate of complications.Results.The mean operative time was shorter in the holmium laser group. A higher SFR was observed in the holmium laser but it was not statistically significant in the URSL and RIRS procedures. The rate of complications was similar in both groups.Conclusions.The URSL and RIRS procedures are highly efficient and safe methods. The use of a holmium laser reduces the duration of the procedure and increases its effectiveness in comparison with the use of a pneumatic lithotripter.

INTRODUCTION Paediatric percutaneous nephrolithotomy (PCNL) has revolutionised the treatment of paediatric nephrolithiasis. Paediatric PCNL has been performed using both adult and paediatric instruments. Stone clearance rates and complications vary according to the technique used and surgeon experience. We present our experience with PCNL using adult instruments and a 28Fr access tract for large renal calculi in children under 18 years. METHODS All patients undergoing PCNL at our institution between 2000 and 2009 were reviewed. Demographics, surgical details and post-operative follow-up information were obtained to identify stone clearance rates and complications. RESULTS PCNL was performed in 32 renal units in 31 patients (mean age: 10.8 years). The mean stone diameter was 19mm (range: 5–40mm). Twenty-six cases required single puncture and six required multiple tracts. Overall, 11 staghorn stones, 10 multiple calyceal stones and 11 single stones were treated. Twenty-seven patients (84%) were completely stone free following initial PCNL. Two cases had extracorporeal shock wave lithotripsy for residual fragments, giving an overall stone free rate of 91% following treatment. There was no significant bleeding or sepsis encountered either during the operation or in the post-operative setting. No patient required or received a blood transfusion. CONCLUSIONS Paediatric PCNL can be performed safely with minimal morbidity using adult instruments for large stone burden, enabling rapid and complete stone clearance.

Background: To evaluate the efficacy and safety of Mini-Percutaneous Nephrolithotomy (PCNL) in the treatment of large (≥15mm) impacted proximal ureteral stones.Methods: This was a prospective observational study and was conducted in the Postgraduate Department of Surgery, Govt. Medical College, Srinagar. A total of 60 patients were included in this study.Results: The mean age (in years) of patients was 38.5±9.31 and range 22-58, the male female ratio was 40:20, the disease laterality (right: left) was 48:12, the mean stone size (in mms) was 17.6±2.11. All the patients were having hydronephrotic kidneys, however, all the renal units were functional. The mean operative time (in minutes) was 62±9.62. The overall success rate was 96.7% after one month of follow-up the stone free rate was 96.7% while as the stone free rate on discharge was 86.7%. The mean hospital stays (in days) was 2.8±1.08. The overall complication rate in this study was 15 patients (25%) which include post-operative fever in 5 patients (8.33%), prolonged hematuria in 4 patients (6.67%), residual stone/disease after 4weeks of follow-up was seen in 2 patients (3.33%) and in 4 patients (6.67%) thoracic complication was seen. However, no ureteral injury, hollow visceral or pelvic perforation was noted. The post-operative analgesic requirement was 100±40.45mgs of Inj. Tramadol. The need of auxiliary procedures was required in 3.3% of patients.Conclusions: Mini-PCNL is both safe as well as an effective therapy for large impacted proximal ureteral stones with a higher success, stone clearance rate and with acceptable complications.

Objectives: To compare the effectiveness and complications of ureteroscopic laser lithotripsy with laparoscopic ureter laparoscopic ureterolithotomy in mid- or proximal portion of large ureteral stones. Material and Methods: We reviewed patients with large (>15 mm) ureteral stone and those who underwent ureteroscopic laser lithotripsy (URS group) or laparoscopic ureterolithotomy (LU group). The first attempt was considered successful in patients who had residual fragments smaller than 2 mm and no conversion of the primary procedure to another. Results: Sixty patients (URS group 29, LU group 31) met inclusion criteria. FURS was used as an adjunctive procedure in one patient for URS group and in two patients for LU group in the same season. LU had a higher success rate and the first-day stone-free rate when compared with URS. Number of procedures was also significantly higher in URS group. There was no difference in stone-free rates at the first and third months, and length of hospitalization and operation were higher in the LU group. Only two patients in the LU group and one patient in the URS group had major complications. Conclusions: Laparoscopy is an effective option of large proximal and mid-ureter stone treatment; however, URS provides similar stone-free rates at three months as a minimal invasive procedure.

Objectives: To report our single center experience in comparing mini-percutaneous nephrolithotomy versus flexible ureterorenoscopy for management of renal stones up to 2 cm in anomalous kidneys. Materials and methods: Records of the last 30 patients with stones less than 2 cm in anomalous kidney treated by mini-percutaneous nephrolithotomy were reviewed and compared to last 30 patients treated by flexible ureterorenoscopy. Results: Mean stone size was significantly higher in the minipercutaneous nephrolithotomy group (17.90 mm) than in flexible ureterorenoscopy group (14.97mm) (p < 0.001). Mean operative time (80.33 min vs 56.43 min) and fluoroscopy exposure time (4.49 min vs 0.84 min) were significantly higher in the mini-percutaneous nephrolithotomy group than in the flexible ureterorenoscopy group (p < 0.001). The mean post-operative drop in hemoglobin concentration was significantly higher in the mini-percutaneous nephrolithotomy group (0.47 gm versus 0.2 gm) (p < 0.001). Stone free rate after 12 weeks follow up was not statistically significant between the 2 groups (90% in minipercutaneous nephrolithotomy vs 80% in flexible ureterorenoscopy) (FEp = 0.472).Conclusions: Both modalities were found to be safe and effective for treatment of stones less than 2 cm in anomalous kidneys.

Objective: Our aim was to determine whether flexible ureterorenoscopy and laser lithotripsy is efficacious and safe in treating lower pole renal calculi. Materials and methods: Patient, procedure and stone data of patients who underwent flexible ureterorenoscopy and laser lithotripsy at our referral centre were collected prospectively between November 2005 and November 2011 and entered into a designated database. In all, 242 procedures were performed in 198 patients. Results: The mean age was 51.2 years. The mean calculi size was 10.51 mm (range 4–27 mm). Thirty seven patients had more than one stone in the lower pole. An access sheath was used in 19 patients (9.6%), 171 (86.4%) had a ureteric stent inserted after the procedure, and 165 patients had a single procedure. Re-operation rate was 16.7%. Stone-free rates after one procedure were 89%, 80% and 41%, respectively, for calculi measuring 4–10 mm ( n=107), 11–20 mm ( n=76) and > 20 mm ( n=15). The overall stone-free rate was 83%, 91% and 95% after one, two and three procedures, respectively. Conclusion: Flexible ureterorenoscopy and laser lithotripsy is a safe and effective minimally invasive treatment option for patients with 4–20 mm lower pole calculi. Staged procedures, however, become necessary as the size of the stone increases greater than 20 mm, and this should be mentioned when counselling patients for their primary procedure.

Objective: This study used the AOFAS score to assess the clinical functional results of patients who underwent tarsal coalition resection. Methods: This was a retrospective case series of patients who underwent tarsal coalition resection to correct rigid flat foot. Clinical and functional assessment was performed with the AOFAS score before and 6 months after surgical treatment. Descriptive analysis was performed for 7 patients (11 operated feet) using measurements of position and dispersion (mean, standard deviation, minimum, median and maximum value) for continuous variables and frequency tables (absolute and relative) for categorical variables. Results: The mean patient age was 10 years, 7 months, and the majority (71.43%) were male. The most affected joint was the calcaneonavicular. The right side was affected in 54.55% of the cases. The most frequent type of coalition was osseous (81.82% of the cases). The mean pre- and postoperative AOFAS scores were 32.7 and 70.2 points, respectively, which was a significant increase. Conclusion: The increased scores after coalition resection was considered the main change between the two assessments. Thus, it can be concluded that in rigid flat feet without severe hind- or forefoot deformities for which conservative treatment failed, bar resection should be the surgical procedure of choice.

Objective: The ongoing Covid-19 pandemic further increased this stress of employees. This disease, which did not have a cure and a vaccine at the beginning, increased the anxiety of the employees and forced them to live separately due to the risk of infecting family members. This study aimed to investigate the burnout levels of doctors and technicians working in Yenimahalle Training and Research Hospital Anaesthesiology and Reanimation Clinic. Materials and Methods: This study was conducted prospectively by using a questionnaire method in the Yenimahalle Training and Research Hospital. Maslach Burnout questionnaire applied to the participants. Quantitative data were expressed as %, the number of subjects as (n). The distribution of continuous variables was evaluated with the Kolmogorov-Smirnow test. Qualitative data were expressed in mean±SD (standard deviation). X2 test was used for comparison of categorical variables. Independent Student T-test was used for comparison of continuous variables. The relationship between burnout level and variables was determined by Pearson Correlation Test. The value of p<0.05 was considered statistically significant. Results: A total of 52 volunteers participated in the study. The average emotional exhaustion score of the volunteers participating in the study was 31.13±4.6, the average depersonalization score was 15.06±3.3, and the mean personal achievement score was 23.60±3.7. There was no statistically significant relationship between any of the variables and the burnout level (p>0.05). Conclusion: The high level of burnout in a clinic that is at the forefront of the fight against Covid-19, such as anesthesiology and reanimation, is important in terms of determining the situation.

The first-line management of renal stones between 20—30 mm remains controversial. The Extracorporeal Shock Wave Lithotripsy (ESWL) stone-free rates for such patient groups vary widely. The purpose of this study was to define factors that have a significant impact on the stone-free rate after ESWL in such controversial groups. Between January 1990 and January 2004, 594 patients with renal stones 20—30 mm in length underwent ESWL monotherapy. Stone surface area was measured for all stones. The results of treatment were evaluated after 3 months of follow-up. The stone-free rate was correlated with stone and patient characteristics using the Chi-square test; factors found to be significant were further analyzed using multivariate analysis.Repeat ESWL was needed in 56.9% of cases. Post-ESWL complications occurred in 5% of cases and post-ESWL secondary procedures were required in 5.9%. At 3-month follow-up, the overall stone-free rate was 77.2%. Using the Chi-square test, stone surface area, location, number, radiological renal picture, and congenital renal anomalies had a significant impact on the stone-free rate. Multivariate analysis excluded radiological renal picture from the logistic regression model while other factors maintained their statistically significant effect on success rate, indicating that they were independent predictors. A regression analysis model was designed to estimate the probability of stone-free status after ESWL. The sensitivity of the model was 97.4%, the specificity 90%, and the overall accuracy 95.6%.Stone surface area, location, number, and congenital renal anomalies are prognostic predictors determining stone clearance after ESWL of renal calculi of 20—30 mm. High probability of stone clearance is obtained with single stone ≤400 mm2 located in renal pelvis with no congenital anomalies. Our regression model can predict the probability of the success of ESWL in such controversial groups and can define patients who would need other treatment modality.
