Abstract:
The complications of percutaneous renal biopsy with Menghini needle, performed in 400 cases by the author, are reviewed. Position of the kidney was located by intravenous pyelography and was checked by further radiography if 1. the pyelogram was of inadequate technique, 2. the kidneys were small, or 3. ptotic. In two thirds of the cases the specimens were taken in duplicates, so as to provide sufficient material for light-, electron-, polarization-microscopic and immunofluorescent studies. On the evidence of the present observations the technique of double biopsy involves no higher incidence of complications than the conventional procedure, nor did it cause complications of major severity in the individual cases.
Insights
Percutaneous renal biopsy using the Menghini needle is a safe procedure. Double biopsy technique for comprehensive analysis shows no increased complication risk compared to standard methods.
Area of Science:
- Nephrology
- Urology
- Pathology
Background:
- Percutaneous renal biopsy is a crucial diagnostic tool.
- The Menghini needle is a common instrument for this procedure.
- Assessing complications and the utility of double biopsy is important for clinical practice.
Purpose of the Study:
- To review complications associated with percutaneous renal biopsy using the Menghini needle.
- To evaluate the safety and efficacy of a double biopsy technique.
Main Methods:
- Review of 400 percutaneous renal biopsies performed by the author using the Menghini needle.
- Kidney position confirmed via intravenous pyelography and radiography.
- Biopsy specimens collected in duplicates for multiple analytical techniques (light, electron, polarization microscopy, immunofluorescence).
Main Results:
- The Menghini needle biopsy procedure in 400 cases was reviewed.
- Double biopsy technique did not increase the incidence or severity of complications compared to conventional biopsy.
- Sufficient material for comprehensive histological and immunofluorescence studies was obtained with double biopsies.
Conclusions:
- Percutaneous renal biopsy with the Menghini needle is associated with a low incidence of complications.
- The double biopsy technique is safe and does not elevate complication rates, while providing ample material for extensive diagnostic studies.
