Objective. To evaluate the safety and effectiveness of transvaginal ultraso
und guided injection of hot saline into the ovarian stroma in polycystic ov
ary syndrome (PCOS) cases in an office based gynecology practice under loca
l anesthesia.
Setting. Outpatient gynecologic clinic.
Study design. Pilot study.
Participants. Fifty-two anovulatory infertile females diagnosed as PCOS by
clinical, chemical and ultrasound criteria were recruited for the study. Al
l cases were resistant to clomiphene citrate for more than 6 months.
Intervention. Injection of warm sterile saline (75C) into the ovarian strom
a under transvaginal monitoring using ovum pickup needle.
Outcome measures. Cycle regularity, ovulation rate and safety were primary
outcomes. Pregnancy rate and patient convenience were our secondary outcome
s.
Results. Ovulation has been achieved in 73.1% of clomiphene citrate resista
nt PCOS cases and resulted in pregnancy in 26.9% of these cases. No adverse
effects were recorded and the procedure was tolerable in most cases.
Conclusion. Transvaginal ultrasound guided ovarian stroma hydrocoagulation
(TOSH) in an office setting seems to be a safe, economic and practical proc
edure that is acceptable by the patients. If larger studies confirm its eff
ectiveness it may be an attractive alternative to conventional ovarian dril
ling.
