Summary
The perurethral-transvesical approach is a preferred method for ultrasound-guided oocyte recovery in in vitro fertilization programs, offering ease of use and reduced contamination risk. This technique resulted in successful pregnancies with minimal complications.
Area of Science:
- Reproductive Medicine
- Ultrasound-Guided Procedures
- In Vitro Fertilization
Background:
- Ultrasound-guided oocyte recovery is crucial for in vitro fertilization (IVF) programs.
- Various approaches exist, including percutaneous-transvesical, transvaginal, and perurethral-transvesical methods.
Purpose of the Study:
- To evaluate and compare different ultrasound-guided oocyte recovery techniques.
- To establish a preferred routine method for oocyte retrieval in an IVF program.
Main Methods:
- The study involved 186 oocyte retrievals performed between January and December 1986.
- Three approaches were initially considered: percutaneous-transvesical, transvaginal, and perurethral-transvesical.
- The perurethral-transvesical approach was selected as the routine technique due to perceived advantages.
Main Results:
- A total of 767 oocytes were collected from 186 retrievals.
- The fertilization rate was 71.8%.
- Forty pregnancies were achieved, with success rates of 21.5% per attempt and 27.7% per embryo replacement.
Conclusions:
- The perurethral-transvesical approach is recommended as a routine technique for ultrasound-guided oocyte recovery.
- This method is considered easier to perform and carries a lower risk of contamination.
- The technique demonstrated a favorable safety profile with only transient hematuria reported as a complication.
