Résumé

Los carcinomas uroteliales son el 4to tumor más común. Pueden ubicarse en el tracto urinario inferior (vejiga y uretra) o en el tracto urinario superior (cavidades renales, pelvis renal y uréter). Presentamos una serie de 3 casos, con cuadro de hematuria macroscópica, documentando tumores uroteliales, realizándose en estos casos un abordaje lumboscópico de riñón y una resección endoscópica del rodete vesical. Se realiza nefroureterectomía lumboscópica con resección de rodete vesical endoscópica transuretral. Los 3 pacientes fueron egresados al segundo día posquirúrgico sin complicaciones y en los tres casos el rodete vesical sin evidencia de actividad tumoral, y actualmente en vigilancia con excelente resultados oncológicos. La nefroureterectomía lumboscópica con resección endoscópica del rodete vesical es una técnica reproducible en manos experimentadas, con iguales resultados oncológicos que el abordaje abierto.


Urothelial carcinomas are the 4th most common tumor. They can be located in the lower urinary tract (bladder and urethra) or in the upper urinary tract (renal cavities, renal pelvis, and ureter). We present a series of 3 cases, with a picture of macroscopic hematuria, documenting urothelial tumors, performing in these cases a lumboscopic approach to the kidney and an endoscopic resection of the bladder rim. Lumboscopic nephroureterectomy was performed with transurethral endoscopic bladder rump resection. The 3 patients were discharged on the second postoperative day without complications and in the three cases the bladder rim without evidence of tumor activity, and currently under surveillance with excellent oncological results. Lumboscopic nephroureterectomy with endoscopic resection of the bladder rim is a reproducible technique in experienced hands, with the same oncological results as the open approach.

Résumé

Objective:To investigate the proliferation inhibitory effect of crocin on transitional cell carcinoma of urinary bladde(rTCCB). Methods:MTT assay was used to evaluate the inhibitory effect of Crocin on the proliferation of T24 cells. Microscope was used to observe the morphological changes of the T24 cells. Flow cytometry was used to measure the cell cycle. T24 cells were inoculated in to BALB/c nude mice to establish bladder cancer model. After treatment with Crocin,the inhibitory effects were observed on the growth of tumors. Results:The proliferation of T24 cells were inhibited remarkably. Morphological changes of cells were observed. Flow cytometric profiles revealed that crocin led to the increase of the cells in G0/G1 phase and the decrease of cells in S phase and G2/M(P

Résumé

Objective To study the effect of pelvic floor electric stimulation on bladder function in goats. Methods 18 goats were randomized into the stimulating and the control group. Results In the stimulating group,the bladder capacity significantly increased by 24%,the voiding pressure significantly declined by 24% and the metabolic level of the detrusor cells is significantly lower. Conclusions Electric stimulation of the pelvic floor would inhibit bladder contraction and may be helpful in the management of instable bladder and stress incontinence.
