Introduction Urinary lithiasis is usually managed by extracorporeal shock wave lithotripsy (ESWL). Patients are examined using non-contrast computed tomography (NCCT) in order to evaluate the feasibility of ESWL, according to where the stone is located and how big is its size. The objective of this study is to determine the outcomes of ESWL in patients having high-density renal stone, evaluated using NCCT. Materials and methods A descriptive case series study was conducted in the Department of Urology, Sindh Institute of Urology & Transplantation, Karachi for six months. Patients of either gender aged between 25-50 years, who presented with solitary renal and ureteric calculi of 0.5-2 cm in diameter and high-density renal stones [>750 hounsfield units (HU)] were enrolled. ESWL was performed and a satisfactory outcome was defined as complete stone clearance in less than or equal to three ESWL sessions. Statistical Package for Social Sciences (SPSS) (IBM Corp., Armonk, NY) was used to analyze frequencies and percentages of the number of ESWL sessions, complete renal stone clearances, and satisfactory outcomes at the end of 12 weeks. A p-value of <0.05 was considered significant. Results The mean age of the patient was reported to be 34.08 ± 9.53 years. 51.6% male preponderance was noticed. Renal and ureteric stones were found in 69.7% and 30.3% of patients, respectively. 21.3% of patients showed stone clearance after two ESWL sessions, 27% of patients after three ESWL sessions, and 51.6% of patients after four ESWL sessions. Stone clearance was found in 58.2% of patients and a satisfactory outcome was found in 42.6% of patients. Conclusions Our results signify a satisfactory outcome of extracorporeal shock wave lithotripsy for high-density renal stone on non-contrast computed tomography. Further studies on a larger scale are needed to validate these results.

Introduction The Jefferson Scale of Empathy in Students or JSE S is a reliable tool to measure the empathy in medical students. I have translated the JSE S into Urdu and measured the empathy in our students along with its reliability and validity. Method This is a cross sectional study of the medical students enrolled at the Muhammad Medical College Mirpurkhas Pakistan. The JSE S was translated into Urdu using the back translation technique. The self administered surveys were distributed to all the 521 medical students of the Muhammad Medical College. The results were analysed using SPSS. Results A total of 405 students returned the forms. The mean empathy score of the medical students was 107 out of 140. Cronbach alpha coefficient was just under 7 for the overall measure. A principal component analysis showed a three factor solution that also provided support for the construct validity of the Urdu version of JSE S version. Conclusion These results have proved that the Urdu version of JSE S version has reasonable reliability and construct validity.

Objectives: To assess the dissection of gallbladder by ultrasonic harmonic scalpel in comparison to electrocautery in laparoscopic cholecystectomy. Study Design: A randomized control trial Study Setting and Duration: Department of Surgery Ward-02 Jinnah Postgraduate Medical Centre, Karachi between June 2018 and February 2019. Methodology: A total of 110 patients diagnosed with cholelithiasis were included in the study. The participants were randomly allocated into two groups i.e., harmonic scalpel group and electrocautery group. Patients were followed postoperatively in the ward and the outcome was measured at the end of two days after surgery. Results: The average age of the patients was 44.56 ± 12.19 years. Out of 110 patients, 30 (27.3%) were male and 80 (72.7%) were female. It was found that the mean operative time (44.4 ± 3.64 min vs. 53.31 ± 8.09 min; p=0.0005), blood loss (10.27 ± 8.35ml vs. 4.00 ± 3.65ml; p=0.0005), post-operative pain (6.87 ± 1.04 vs. 4.29 ± 1.01 p=0.0005), and hospital stay (31.09 ± 10.58 vs. 24.11 ± 0.81; p=0.0005) were significantly lower in harmonic scalpel group than the electrocautery group. Conclusion: Dissection of gall bladder with harmonic scalpel is safe and easy method and superior then electrocautery and can routinely be used if available. Keywords: Laparoscopic cholecystectomy, Harmonic scalpel, Electrocautery

There is a continued debate on fate of spilled bile with gallstones during laparoscopic cholecystectomy, so we felt that the outcome needs further evaluation in detail. Although laparoscopic cholecystectomy become increasingly popular, but it is associated with a slightly higher chances of injury to biliary tree and perforation of gallbladder with spillage of bile only or with gallstones. Objectives: (1) To evaluate fate of spilled bile with gallstones during laparoscopic cholecystectomy. (2) To assess various possible outcomes. (3) Suggestions to prevent these and their management. Design of study: Prospective study. Setting: Surgical unit of Muhammad Medical College Hospital, Mirpurkhas. Period: February 2008 to April 2011. Data source: Total 100 patients who underwent elective laparoscopic cholecystectomy were included. Age, sex, duration of operation, operative findings, duration of hospital stay and post-op complications were recorded in proforma and analyzed on SSP version 10. Material and method: The patients who underwent cholecystectomy, and had intra-operative spillage were shortlisted, included in this study and followed up. Short-term follow-up was based on OPD visits for 2 to 3 weeks postoperatively, and long-term follow-up was achieved by regular OPD visits or telephone conversation in patients at a mean of 1.4 years (range 2 to 39 months).all minor or major complications were recorded in preformed proforma. Results: A total of 100 patients underwent laparoscopic cholecystectomy. Among the patients who underwent elective laparoscopic cholecystectomy the incidence of Iatrogenic perforation of the gallbladder is around 40%, of whom about 22% had spillage of only bile and 18% in whom spillage of both bile and gallstones. Conclusions: It is concluded that laparoscopic cholecystectomy with gall bladder perforation along and spillage of bile and stones took longer operative time than intact gall bladder. We suggest that attempts should be made to irrigate the operative field to evacuate spilled bile and to retrieve all gallstones spilled during the operative procedure. In our study, we revealed that no harm is caused by retained gallstones during laparoscopic cholecystectomy after long term followup by evaluation.
