Outcomes and Indications of Mini Percutaneous Nephrolithotomy in Zagazig University Hospitals Patients

Abstract

Background: PCNL is a well-established treatment option for patients with large and complex renal calculi. In order to decrease morbidity associated with larger instruments like blood loss, postoperative pain and potential renal damage. A modification of the technique of standard PCNL has been developed. This is performed with a miniature endoscope via a small percutaneous tract (11–20 F) and was named as minimally invasive or mini- PCNL. Objectives: To improve medical service for patients attending for Zagazig University Hospital by determining indications and outcomes of M-PCNL when used as treatment modality for patients with renal stones. Methods: This prospective cohort study was conducted at Urology Department Zagazig University Hospitals during the period from March to November 2019. 48 patients from those attending to Urology Outpatient Clinic. Percentage of improvement of patients M-PCNL was 94%, so sample was calculated to be 32 patients using open EPI with CI 95%. Results: 48 patients and percentage of improvement of patients M-PCNL was 94%. Male represented 53.8% of the studied patients. Mean age was 35.10 years, ranged from 18 to 60 years. Mean body mass index was 39.56 kg/m2, ranged from 18.60 to 63.20 kg/m2. Mean preoperative hemoglobin was 12.56 g/dl, ranged from 11 to 14 g/dl. The most common site of stone was renal pelvis in 44.6% of the studied patients. Mean stone density was 1024.76, ranged from 220 to 1500. Mean stone size was 1.86 mm, ranged from 1.20 to 3-mm. Mean tract diameter was 16.92 mm, ranged from 14 to 18 mm. Conclusion: Mini-PCNL was safe and efficacious in treatment of patients with renal stone disease.
