FREQUENCY OF MACROSCOPIC HAEMATURIA AFTER RENAL BIOPSY

Background; Macroscopic hematuria is a commonly seen condition in the emergency department (ED), which has a variety of causes. This study was performed to ascertain frequency of macroscopic hematuria among patients undergoing native renal biopsy using free hands ultrasound assisted renal biopsy technique within first 24 hours, as there is no such study done in Pakistan on this topic. Objective: To determine frequency of macroscopic hematuria after native renal biopsy using free hands ultrasound assisted renal biopsy technique within first 24 hours. Material and Methods: A total of 138 patients from Department of Nephrology, Jinnah hospital, Lahore, Pakistan were taken for macroscopic hematuria. Data was analyzed by SPSS. Results: Of these 138 study cases, 91 (65.9 %) were male patients while 47 (34.1%) were female patients. Mean age of our study cases was 47.57 ± 7.26 years (with minimum age of our study cases was 35 years while maximum age was 60 years). Of these 138 study cases, 56 (40.6%) belonged to rural areas and 82 (59.4%) belonged to urban areas. Monthly family income up to Rs. 350000 was noted in 67 (48.6%) while more than 35000 rupees 71 (51.4%) of our study cases. Obesity was present in 41 (29.7 %) of our study cases. Chronic kidney disease (un-explained renal failure) was noted in 77 (55.8%), proteinuria in 46(33.3%) and unresolved AKI in 15 (10.9%) of our study cases. Mean needle size was noted 17.15 ± 0.59 and 86 (62.3%) had needle size with gauge 18. Macroscopic hematuria was noted in 30 (21.7%) of our study case. Conclusion; High frequency of macroscopic hematuria after native renal biopsy using free hands ultrasound assisted renal biopsy technique was noted in our study. Macroscopic hematuria was significantly associated with male gender, increasing age, residential status, monthly family income and indications for renal biopsy. The early diagnosis followed by corrective/preventive measures can help decrease disease morbidity among targeted population. This will help decrease disease burden and improve quality of life of these patients
