Abstract


Background: Obstructive uropathy is a common problem in urologic practice; temporary relief of obstruction in the upper tract poses a significant challenge. Ultrasound‑guided percutaneous nephrostomy (PCN) is an option for upper tract drainage; compared to fluoroscopic guidance, it is readily available, affordable, and not associated with radiation exposure. We present our experience with ultrasound‑guided PCN. Patients and Methods: We studied all patients who had ltrasound‑guided PCN in our center between January 2013 and January 2017. Information obtained included the patients’ demographics, clinical details, primary pathology, indications, outcome, and complications within 30 days. Relevant data were extracted and analyzed using descriptive statistics. Results: A total number of 35 PCNs were performed in 26 patients within the period of study. The median age was 44.5 years. There were 17 females and 9 males. About 88.2% of the females had ureteric obstruction from advanced carcinoma of the cervix while the predominant cause of obstruction in the males was advanced carcinoma of the bladder. Kidney access under ultrasound guidance required well dilated collecting systems for success and ease of puncture. The most common complication was hematuria, which resolved within 24–48 h in all patients uneventfully. Conclusion: PCN is an important and common procedure for temporary relief of upper urinary tract obstruction. While fluoroscopic guidance provides superior image guidance, ultrasound guidance is comparatively reliable, albeit with a longer learning curve. Adequate training, careful patients selection, and patience are key to success.
