A cecostomy technique (surgery for inserted tube into ceca) was developed to quantify urine backflow into the ceca of fed and feed-deprived chickens. Two days post-surgery, cecostomised chickens were flushed with 20ml of warm saline solution every other day for 10 days. Excreta were collected daily from cecal tubing and cloaca by surgical attachment of polyethylene collection vessels to the chickens. Uric acid excretion was significantly increased in fed compared to feed-deprived chickens (P<0.05). Amount of determined uric acid from the ceca was 7.74% and 5.31% of total excretion for fed and ffeed-deprived chickens, respectively. Post-mortem examinations ascertained that the caeca were intact around the Latex tubing. The results of the study indicated that at least 5% of daily urine production flow retrograde into the ceca of roosters.

A caecostomy technique (surgery for inserting tube into caeca) was developed to quantify urine backflow into the caeca. Two days post-surgery, caecostomised chickens were flushed with 20 ml of warm saline solution every other day for 10 days. After surgery birds temporarily lost appetite and activity, but they were restored gradually in a few days. The incision healed within 10 days post-surgery. Excreta were collected daily from caecal tubing and cloaca by surgical attachment of polyethylene collection vessels to the chickens. Post-mortem examinations ascertained that the caeca were intact around the Latex tubing.

An urinoma(uriniferous pseudocyst, pararenal pseudocyst) denotes an encapsulated collection of urine in the perirenal or paraureteral space. It was usually reported in relation to trauma and acquired obstructive uropathy but rarely reported in renal infection including renal candidiasis. The mechanism is believed due to rupture of fornix through weakened portion of suppurated kidney and pyelosinus backflow by increased intrapelvic pressure in obstructive uropathy and fungus ball obstruction. We report a case of urinoma in a premature as the first case in Korea which developed as a complication of renal candidiasis.

This study sought to measure the absorption of commercially available urinary incontinence panty by applying a method of measuring the maximum saline amount of adult diapers in an international standard. The subject was 15 products from 3 brands on the market, and the SPSS 27.0 program was used for analysis. As a result of measuring the maximum absorption of commercial incontinence panty, it was found that the maximum absorption of product B was the highest and the maximum absorption of product C was the lowest. Even though the product was marked with the same absorption amount, it showed differences in the same product of the same brand, and it also showed differences depending on the brand. The reflux amount of the injected physiological saline and the urinary incontinence panty showed a positive (+) correlation, and as the amount of the injected physiological saline increased, the reflux amount of the urinary incontinence panty increased. It was analyzed that the time when the leakage begins and the amount of leakage have a negative (-) correlation. In future research, it is believed that the development of functional pads that can increase absorption and reduce reflux and leakage should be carried out.

Purpose : Intrarenal reflux(IRR) is backflow of urine from the renal pelvis into the collecting ducts. IRR is the main cause of renal injury in children with vesicoureteral reflux (VUR) which leads to renal scars, hypertension, proteinuria, and chronic renal failure. The purpose of our study was to investigate the characteristics of intrarenal reflux. Method : We retrospectively reviewed the medical records of 80 patients who were diagnosed as having grades of III-V VUR from Jan. 2004 to Dec. 2006 in the department of pediatrics in Ajou University Hospital. The patients were divided into two groups according to the presence of IRR on voiding cystoureterogram and compared to each other for the possible factors associated with intrarenal reflux. Results : Among 80 VUR patients, IRR(＋) group comprised 17(21.3%) patients and 27 renal units(23.2%) and revealed younger age, higher grade of VUR, and more proteinuria compared to IRR(-) group. There were no significant difference in gender, laboratory findings and the rate of resolution in VUR or defects on renal scan between two groups. Also, intrarenal reflux mostly corresponded to the same site of photon defects on DMSA scan. Conclusion : We suggest that intrarenal reflux tends to be associated with younger age, higher grade of reflux, more proteinuria with no difference in resolution rate of VUR when compared to the VUR patients without IRR. From this study, we were able to understand the characteristics of intrarenal reflux in children with urinary tract infection.
