RESUMEN
PURPOSE: A major advantage of transperineal sonography (TPUS) is its ability to evaluate the cervix without causing any distortion. This study was performed to compare transvaginal sonography (TVUS) and TPUS at 24 weeks of gestation in predicting preterm delivery in low-risk pregnancy. METHODS: Three hundred fifty-seven pregnant women underwent TVUS and TPUS at 24 weeks of gestation. The relationship between cervical length and preterm delivery was assessed. Accuracy values of TVUS and TPUS at 24 weeks of gestation were compared in predicting preterm delivery. RESULTS: Preterm delivery (before 36 weeks of gestation) occurred in 22 pregnancies (6.2%). Mean cervical lengths measured by TVUS and TPUS were significantly different in preterm and term delivery groups (P < 0.05). Areas under the curves were 0.801 and 0.857 for the transvaginal and transperineal measurements, respectively. The coefficient of correlation between the transvaginal and transperineal cervical length measurements was 0.83. TPUS had a sensitivity of 77% in predicting preterm delivery, with a false-positive rate of 17% and a relative risk of 4.5 at the 32.5-mm cutoff value. CONCLUSIONS: When the cervix is well visualized, TPUS can predict preterm delivery as accurately as TVUS.

OBJECTIVE: To determine the effects of ovarian wedge resection by minilaparotomy in infertile patients with polycystic ovarian syndrome (PCOS). STUDY DESIGN: One hundred and thirty-four anovulatory patients with PCOS, who were previously treated with clomiphene citrate and gonadotropins and did not conceive were operated via minilaparotomy with microsurgical principles and ovarian wedge resection was performed on each subject. Pregnancy rates and adhesion formation were investigated retrospectively. RESULTS: A total of 121 pregnancies were achieved in 2 years (90%). One hundred and four patients conceived within the first 6 months (78%) and the remaining 17 patients conceived within 2 years (13%) following the operation. Sixty-eight patients had a second pregnancy later. In the post-operative period, 24 patients had cesarean delivery and 20 had diagnostic laparoscopy. Out of these 44 patients, only 5 of them were found to have minimal adhesions. CONCLUSION: This technique offers high pregnancy rates and minimal adhesion formation. Ovarian wedge resection by minilaparotomy might be an alternative treatment approach in patients with PCOS who did not conceive with standard ovulation induction protocols.
