Lesions produced by the Extravasation of Urine from the upper urinary tract.
Histopathology, 1997Co-Authors: R.a. Carr, J. Newman, G.n. Antonakopulos, M.c. ParkinsonAbstract:We present six cases which illustrate the spectrum of clinical features, macroscopic findings and light microscopic findings of Urine Extravasation from the upper urinary tract. The early lesions are characterized macroscopically by an oedematous, glistening or gelatinous appearance to the renal perihilar and peripelvic fat. Light microscopically there is lipolysis with associated foamy macrophages, multinucleate giant cells and lymphocytes. Immunohistochemical staining for Tamm-Horsfall protein is strongly positive in the extracellular space and in the foamy macrophages confirming Urine Extravasation. Later lesions are characterized by cicatrization of fibrous tissue around the renal pelvis and hydronephrosis. Microscopically there is relatively bland fibrosis with occasional lymphocytes and histiocytic cells. The late lesions are also characterized by extracellular deposits of weakly eosinophilic, granular or hyaline material, the so called 'urinary precipitates'. These deposits stain strongly with diastase PAS and weakly positive for Tamm-Horsfall protein. The staining of these urinary precipitates is analogous to renal tubular hyaline casts, thus supporting the theory that they are derived from uroproteins. We consider that these deposits are pathognomic of past Urine Extravasation.

Periurethral constrictor in pediatric urology: Long-term followup
The Journal of Urology, 2004Co-Authors: Fabio O. Vilar, Luiz Alberto P. Araujo, Salvador Vilar Correia LimaAbstract:ABSTRACTPurpose:: We report long-term followup of a new device for the treatment of urinary incontinence in children.Materials and Methods:: A periurethral constrictor was implanted in 29 boys and 13 girls 3 to 17 years old (mean age 10.2, median age 10) during the last 9 years. Of the patients 29 had neurogenic bladder, 12 had bladder exstrophy and 1 had megalourethra. Bladder augmentation was done simultaneously in 34 patients. The device was implanted around the bladder neck in 41 cases and at the bulbous urethra in 1. Continence was achieved in all cases when the device remained in situ.Results:: Followup ranged from 4 to 104 months (mean 63, median 75). In 23 patients (82.1%) in the neurogenic group and the patient with megalourethra the device remains in situ and continence is preserved. Clean intermittent catheterization is performed without difficulty. In 4 patients the device was extracted due to erosion or infection. The device was extracted due to erosion and Urine Extravasation in 10 exstrophy...

Periurethral constrictor in pediatric urology: long-term followup.
The Journal of urology, 2004Co-Authors: Fabio De O Vilar, Luiz Alberto P. Araujo, Salvador Vilar Correia LimaAbstract:We report long-term followup of a new device for the treatment of urinary incontinence in children. A periurethral constrictor was implanted in 29 boys and 13 girls 3 to 17 years old (mean age 10.2, median age 10) during the last 9 years. Of the patients 29 had neurogenic bladder, 12 had bladder exstrophy and 1 had megalourethra. Bladder augmentation was done simultaneously in 34 patients.

Followup ranged from 4 to 104 months (mean 63, median 75). In 23 patients (82.1%) in the neurogenic group and the patient with megalourethra the device remains in situ and continence is preserved. Clean intermittent catheterization is performed without difficulty. In 4 patients the device was extracted due to erosion or infection. The device was extracted due to erosion and Urine Extravasation in 10 exstrophy group patients. Two patients have the device and perform post-void catheterization. Based on the data from this long-term study we conclude that the periurethral constrictor is a safe alternative for the treatment of urinary incontinence in children. Like other devices it must be used with caution in cases of bladder exstrophy.

Prevention and Cure of the Complication of Transurethral Resection of Prostate
Journal of Tropical Medicine, 2010Co-Authors: Chen WeiAbstract:Objective To review the intra and postoperative complication of transurethral resection of prostate (TURP) and find some way to improve the safety of TURP. Methods The clinical data of 726 patients (1998-2008) were analyzed for the complications after TURP retrospectively. Results There were no dead cases. The mean operative time was 83 min. Transurethral resection (TURS) occurred in 16(2.2%) cases,postoperative bleeding in 8(1.1%) cases,Urine Extravasation in 6(0.8%) cases,urinary incontinence in 17(2.3%) cases,dysuresia and urethral stricture in 21(3.0%) cases,urinary tract infection in 11(1.5%) cases,sexual disturbance in 30(4.1%) cases. Conclusion TURP is safe if the complications can be treated in time. Most of the complications are closely related to the technology of the operators.
