|August 1, 1984
Summary
Percutaneous nephrostomy (PNS) shows minimal long-term effects on kidney morphology and function. This minimally invasive procedure is considered safe, with few late complications observed in patients.
Area of Science:
- Nephrology
- Radiology
- Urology
Background:
- Percutaneous nephrostomy (PNS) is a common procedure for urinary tract drainage.
- Long-term effects of PNS on renal morphology and function require further investigation.
Purpose of the Study:
- To evaluate the late morphological and functional effects of percutaneous nephrostomy (PNS) on the kidney.
- To assess the safety of PNS by examining kidney structure and function years after the procedure.
Main Methods:
- Renal scans and dynamic CT studies were performed on 36 patients.
- Imaging was conducted at least three years after percutaneous nephrostomy (PNS).
- Kidney morphology and function were assessed for late effects.
Main Results:
- Only one kidney exhibited a cortical scar (1x1x1 cm) at the puncture site.
- No significant loss of renal function or alterations in the collecting system were observed.
- Minimal findings included slight capsular fibrosis, posterior displacement, and perirenal scarring in a small number of kidneys.
Conclusions:
- Morphological alterations following PNS were minimal and less severe than those from open surgery.
- The low complication rate and minimal late effects suggest percutaneous nephrostomy (PNS) is a safe procedure.
- PNS can be considered a safe intervention for kidney drainage with favorable long-term outcomes.
