Etiology of right sided hydronephrosis in pregnancyFrom: DuBose, Terry (DuboseTerryJ@uams.edu)Thu Apr 28 10:12:28 2005
I need some help finding an explanation of why maternal hydronephrosis is more common on the right side than the left. Seems I read somewhere, years ago, that it has to do with the left iliac artery protecting the left ureter from compression, while the right iliac is more midline and the uterus can compress the right ureter. I found the following abstract, but unfortunately do not have access to the electronic version... and will not be able to get to the library this week. I doubt it will explain the etiology anyway. Anyone have a reference or good explanation for this phenomenon? Thanks, Terry Terry J.

Gingell JC. Institution Department of Obstetrics, Southmead Hospital, Bristol. Title Ureteric obstruction in pregnancy--diagnosis and management. Source British Journal of Obstetrics & Gynaecology. 98(11):1137-40, 1991 Nov. Local Messages All @ UAMS Abstract OBJECTIVE--To discuss the aetiology, diagnosis and management of ureteric obstruction in pregnancy and to describe the use of double-pigtail ureteric stents in a series of 10 patients. DESIGN--Retrospective study of women presenting to a maternity unit in whom the diagnosis of ureteric obstruction is reached. SETTING--Southmead Hospital in Bristol; a large district general hospital with a throughput of around 6000 maternity patients per year. SUBJECTS--10 women (8 in their first pregnancy, 1 in her second and 1 in her third; mean age 29.2 years (range 18-31 years). INTERVENTIONS--Double-pigtail ureteric stents were electively passed after a diagnosis of ureteric obstruction. Stents remained in situ for a mean 15.5 weeks (range 8-25 weeks) and were electively removed 4-6 weeks post partum. RESULTS--Nine women progressed uneventfully through the remainder of their pregnancy. One developed strangury, haematuria and discomfort after stent insertion. Seven women had normal vaginal deliveries, two assisted vaginal deliveries and one was delivered by caesarean section. None required to have external urinary drainage. CONCLUSIONS--Double-pigtail ureteric stents are easy to place and remove and are well tolerated. They provide a simple, safe and effective method of internal upper urinary tract drainage in ureteric obstruction in pregnancy.
