Urinary tract injuries during obstetric intervention 总被引:11,自引:0,他引:11

A retrospective case record review of obstetric urinary tract injury in the Grampian region from 1976 to 1993 identified 16 cases of bladder injury (0.1 per 1000 deliveries, 1.4 per 1000 caesarean sections and four cases of ureteric injury (0.03 per 1000 deliveries, 0.27 per 1000 caesarean sections). Diagnosis of bladder injury was immediate, but of ureteric injury often delayed. Although the injury rates are lower than previously reported and previously reported risk factors not confirmed, this audit has resulted in guidelines for junior staff, compliance with which will be monitored, and every case of urinary tract injury will be reviewed. 相似文献

Oligohydramnios-polyhydramnios sequence in twin pregnancies may be managed by aggressive amniocentesis and is described in nine consecutive cases. In four of the nine pregnancies both twins survived, one pair died in the neonatal period, and the other four pairs all suffered intrauterine death. The median number of amnioreductions performed was five (range 2–7). In this series the reaccumulation of urine in the bladder of the 'stuck twin' was a predictive prognostic marker of survival in both twins, with a sensitivity and specificity of 100%. 相似文献

Reversal of sterilisation by the railroad technique 总被引:1,自引:0,他引:1
L. C. Edozien Senior Registrar D. Anastassopulos Staff Grade A. M. Mander Consultant 《BJOG : an international journal of obstetrics and gynaecology》1997,104(1):92-95
Objective To show that a simple, easily learned and relatively inexpensive method of reversal of sterilisation provides good results.
Design Retrospective observational study.
Setting An NHS Trust Hospital.
Sample Sixty-seven women aged 19 to 39 years who underwent reversal of sterilisation between January 1984 and December 1993.
Main outcome measures Pregnancy rate following reversal; rate of ectopic pregnancy.
Results Thirty-four women (51%) had intrauterine pregnancies after reversal of sterilisation; intrauterine pregnancy rate in women who had been sterilised with rings or clips was 64%. Five women (7.5%) had ectopic pregnancies.
Conclusion This technique provides results that compare favourably with those of microsurgery. It offers hope to couples who do not meet the restrictive criteria for microsurgery and in vitro fertilisation and should appeal to purchasing authorities. 相似文献
