Summary
Measuring intrapelvic pressure (IPP) using a simple ureteral catheter device aids in diagnosing renal colic. This method reveals elevated IPP in patients with renal colic, particularly in females.
Area of Science:
- Urology
- Nephrology
- Medical Devices
Context:
- Acute ureteral obstruction leads to elevated intrapelvic hydrostatic pressure.
- Accurate diagnosis of renal colic is crucial for timely intervention.
- Existing methods for pressure measurement may be complex or invasive.
Purpose:
- To introduce a simple device for estimating intrapelvic pressure (IPP).
- To establish normal IPP ranges in healthy individuals.
- To quantify IPP variations in patients experiencing renal colic.
Summary:
- A novel, simple device using a ureteral catheter and polyethylene tube was developed to measure intrapelvic pressure (IPP) in centimeters of urinary column.
- Normal IPP in 187 healthy individuals ranged from 0.5 to 14.2 cm, with higher mean values in females.
- In 187 renal colic patients, IPP ranged from 55 to 150 cm, with mean values of 97.4 cm in females and 89.8 cm in males during colic episodes.
- Elevated IPP was consistently observed in renal colic patients compared to healthy individuals, with females exhibiting higher mean IPP.
Impact:
- Provides a straightforward method for objective diagnosis of renal colic.
- Highlights the significance of IPP measurement in managing conditions like anuria and acute pyelonephritis.
- Offers valuable insights into the sex-based differences in intrapelvic pressure during renal colic.
