Abstract

Background:&nbsp;Despite its historical significance, ESWL has witnessed changes in its role, necessitating refined technical approaches and stringent patient selection criteria for optimal outcomes. This study aims to assess the efficacy of extracorporeal shock wave lithotripsy (ESWL) for treating renal pelvis stones ranging from one to two centimeters in size.Methodology:&nbsp;A descriptive case series was conducted at the Department of Urology and Renal Transplantation, SIUT, Karachi. The study enrolled 81 patients aged 20 to 60, of both genders, with a single renal pelvis stone sized 1 2 cm. Patients with ureteral obstruction were excluded. Informed consent was obtained before performing extracorporeal shock wave lithotripsy (ESWL). Follow ups were carried out regularly, and final success was assessed one month post ESWL session.Results:&nbsp;The mean age of participants was 41.93 ± 9.67 years, with the majority (54.32%) falling within the 41 to 60 age range. Out of 81 patients, 49 (60.49%) were male and 32 (39.51%) were female, resulting in a male-to-female ratio of 1.5:1. The mean stone size was 14.22 ± 2.01 mm. In the study, the success rate of ESWL for renal pelvis stones sized 1-2 cm was 85.19%, with 69 patients showing successful outcomes.Conclusion:&nbsp;In conclusion, the success rate of ESWL for treating renal pelvis stones sized 1-2 cm is notably high. This finding underscores the effectiveness of this non-invasive procedure in managing such cases.

Research Objective

To assess the efficacy of extracorporeal shock wave lithotripsy (ESWL) for treating renal pelvis stones ranging from one to two centimeters in size.

Methodology

A descriptive case series design was employed. The study was conducted at the Department of Urology and Renal Transplantation, SIUT, Karachi, from December 3, 2018, to June 2, 2019. 81 patients aged 20 to 60 with a single renal pelvis stone sized 1-2 cm were enrolled. Patients with ureteral obstruction were excluded. Data was analyzed using SPSS version 22.0 with descriptive statistics and stratification analysis.

Discussion

The study highlights a high success rate for ESWL in treating renal pelvis stones of 1-2 cm, aligning with previous research. The non-invasive nature, minimal failure rate, and avoidance of anesthesia make ESWL a viable primary treatment option for such cases.

Key Findings

The overall success rate of ESWL for renal pelvis stones sized 1-2 cm was 85.19% (69 out of 81 patients). Patients aged 20-40 years had a success rate of 88.64%, while those aged 41-60 years had a success rate of 81.82%. Males had a success rate of 89.86% and females 81.25%.

Conclusion

Extracorporeal shock wave lithotripsy (ESWL) demonstrates a high success rate for treating renal pelvis stones within the 1-2 cm size range, underscoring its effectiveness as a non-invasive procedure.

Fact Check

1. Success Rate: The study reports an 85.19% success rate for ESWL in treating renal pelvis stones of 1-2 cm.
2. Patient Demographics: The mean age of participants was 41.93 ± 9.67 years, with 49 (60.49%) being male and 32 (39.51%) female.
3. Stone Size: The mean stone size investigated was 14.22 ± 2.01 mm.
