Background: Genital prolapse is a common gynaecological problem in developing country like Bangladesh.Objectives: The aim of this study was to evaluate the advantages of short term catheterization in comparison to long term catheterization after genital prolapse surgery. Methodology: This was a prospective analytical cross sectional study being carried out from 1st July 2005 to 30th July 2006 in the Department of Gynaecology & Obstetrics of Sir Salimullah Medical College & Mitford Hospital. A total of 200 patients undergoing genital prolapse surgery were selected for this study. Patients were divided into two groups. In short term catheterization group the urinary catheter was withdrawal within one day after surgery and in the short term catheterization group the catheter was remained in situ for 5 days after surgery. Result: Positive urine culture was found in 16% in long term catheterization group compared with 6% in short term group (P=0.02). Mean duration of hospital stay was 6.98 days in long term catheterization group and 4.68 days in short term catheterization group (P<0.01). Residual volume was more than 200 ml and need for re-catheterization occurred in 3% in group whereas it was 10% in case group (P=0.04). Conclusion: This study permits to conclude that short term catheterization is better than long term catheterization.

Abstract A marine operation is a complex non-routine activity of limited duration carried out in offshore environment. Due to safety reasons, these operations are normally performed within specific sea state limits, which are derived from numerical modelling and analysis of hazardous events. In view of the uncertainties in the assessment of structural responses under stochastic environmental conditions, these limiting curves correspond to a target structural failure probability recommended in offshore standards (for example, 10−4 per operation as specified by DNV-GL). However, one of the main limitations is that these curves do not reflect site-specific safety assessment. The current paper presents a novel methodology for assessing the structural safety level of marine operations from a long-term perspective. The methodology includes estimation of extreme response distribution under all possible operational sea states (i.e. the operational domain under the limiting sea states) for a given offshore site and is compared to the response limit to obtain an average failure probability. A case study is also presented for a blade root mating process onto preassembled hub using a jack-up crane vessel and risk of impact between root and hub is considered critical. Global time-domain simulations are performed using multibody dynamics, and extreme value distributions for impact velocities are derived for different wind-wave conditions. The allowable impact velocity between the blade root and the hub is determined by an explicit finite element analysis of the damage at the blade root. Finally, the average failure probabilities considering the operational domain are obtained for four different European offshore sites and are compared to the target level of structural failure probability considered for the limiting sea states.
