A thorough statistical analysis of the results of drainage types and drain properties adopted in 3327 cases of genitourology operated upon in 5 years showed the following 1. Due to rich vascularity of the genito urinary organs, the usual urine collection drainage has become a must 2. Drain by plastic or silicon coated corrugated sheet or multiparous tubes gave better results 3. The suitable breadth of the sheet drain is of 3 corrugations while the optimum size of the tube or catheter is Fr 16 or 14.< 4. Multiple tubular sheet silicon coated may not sensibly be the best drain, as pores are narrow. Besides, this was not available in this work 5. Gauze drain is not suitable in urological drain as harbours infection due to presence of urine, thus should be avoided 6. As regards the site of drain fixation, the split one i.e. from a stab incision about 1 inch from the wound incision is superior to the traditional drain from the wound incision itself Moreover, the interior end of the drain should be located in the most dependent part of the depth of the operation 7. The surface length of the drain should be neither too long to hinder dressing nor too short to retract inside the wound edges; 3 cm are satisfactory 8. Consistency of the drain not to be too soft as it may impede drainage when compressed by oedema of the healing woundas well as it would be liable to cut off on removal. On the other hand, the hard drains are painful to the healing sensitive tissues of the operation on movement 9. Mulitplicity of individual drains may be helpful and necessary However, it is contraindicated to use the drain by cleavage of its interior segment 10. Drainage efficiency implies insinuating the drain into the most independent part of the operative wound to avoid blood and/ or urine collection 11. Removal of the drain is to be experienced gently, if it resists extraction no force is exerted and is left for extra time till< any probable unnoticeable catgut stitch hitching it, is absorbed 12. The most suitable period of drainage is for 6 days. However when intestine is involved as a step of operation, peritoneal drainage may be exceptional as long as 12 to 15 days 13. The mean hospital stay is shortest in the second group of drainage (6 days period) with consequently less hospital running expenses, besides a more satisfaction to both the patient and the surgeon. |
