Ultrasound guided tube drainage of perinephric abscess: Experience of 70 cases.

Objective: To determine the efficacy of ultrasound guided tube drainage of Perinephric abscess. Study Design: Observational study. Setting: Surgical Unit-II and Urology Ward Ghulam Muhammad Mahar Medical College Teaching Hospital Sukkur & Mustafia Hospital Sukkur. Period: February 2016 to January 2020. Material & Methods: 70 cases with Perinephric abscess underwent ultrasound guided tube drainage. Diagnosis was established by history, clinical examination, investigations like ultrasound & CT scan. Patients with emphysematous kidney & chronic sinus formation and with small abscess were excluded from the study. Patients were followed up for 4 weeks for complete regression of abscess cavity on ultrasound. Results: Out of 70 Patients 61.4% were male and 35% were female. 58.5% of the patients had right sided Perinephric abscess. Majority of the patients(42.8%)  belonged to age group 41-50 years. 31.4% of the patients were diabetic. Clinically 95.7% of the patients reported with fever and 88.5% with flank pain. Ultrasound guided tube drainage was successful in 65(92.8%) while in 5(7.1%) patients it failed and open drainage was performed. Conclusion: Ultrasound guided tube drainage is an effective way to treat Perinephric abscess with very few minor complications as compared to open drainage.
