Laparoscopic uretero-ureterostomy for iatrogenic lesions of the distal ur éter.
We describe the technique for the repair of distal ureter lesions that preserves both anatomy and function of the urinary tract (1). The operation consists in dissection and extraction of the distal ureteral stump from its intramural tract to get at least 1 cm of free ureter, percutaneous insertion of a ureteral stent, checking the absence of tension between proximal ureter and distal dissected stump, end to end anastomosis and reinsertion of the distal ureter in the previously dissected bladder muscle layer. We present 4 cases of ureteral injury after laparoscopic simple total hysterectomy for uterine myomas with complete section of the distal ureter, that were operated 3-5 days after injury, performing laparoscopic repair surgery. We performed clinical and radiological control with intravenous urography demonstrating ureteral continuity normalization and good renal function. We believe that repair of the urinary tract with anatomical and physiological preservation must be the first option in the laparoscopic treatment of complete distal ureteral injuries, and intramural ureter dissection when needed avoids the performance of ureteroneocystostomy. It is necessary to keep progressing in the technique improvement, and to increase the number of cases and experience. PMID: 28530622 [PubMed - in process]
In this study, we explored the central roles of mitochondria and the mechanism of the protective effect of the mitochondrial targeted peptides in tubular cell apoptosis and interstitial fibrosis during obstructive nephropathy. Unilateral ureter obstruction (UUO) was performed on rats, and the animals were randomly assigned to intravenous treatment with normal saline, rat serum albumin (RSA), or HOCl-rat serum albumin (HOCl-RSA) in the presence or absence of SS-31. A sham-operation control group was set up by left ureteral dissociation but not ligation. Compared with the control group, UUO animals displayed fibrotic abnorma...
Ureteral-arterial fistulas are a rare and life-threatening source of hematuria. They are caused by inflammatory and fibrocystic changes that become erosive defects between the ureter and adjacent iliac arteries. They occur more frequently in women and are associated with pelvic irradiation, ureteral and arterial manipulation, malignant disease, and pelvic or abdominal surgery. Here we describe one case and review five cases of endovascular repair.
The present paper described a rare case of ureteral IgG4-related disease (IgG4-RD) that mimicked urothelial carcinoma. An otherwise healthy patient presented with CT, ureteroscopic and biopsy findings that were suspicious of urothelial carcinoma. The patient received a right nephro-ureterectomy. Histopathology showed ureteral IgG4-RD, without evidence of urothelial carcinoma. Accurate diagnosis of this rare entity should be based on clinical, biochemical and histopathological findings.
DiscussionDetermining whether ESWL is not inferior clinically and is cost-effective compared to ureteroscopic treatment as the initial management in adults with ureteric stones who are judged to require active treatment is relevant not only to patients and clinicians but also to healthcare providers, both in the UK and globally.Trial registrationISRCTN registry,ISRCTN92289221.

ConclusionCompared to the SHS data set SWL was in general associated with hypertension and diabetes. However, no clear difference between patients after SWL to the kidney compared to SWL to the distal ureter was seen and thus the data do not support a causal relationship.
To define the need for emergent intervention between patients with SBUC compared to unilateral ureteral calculi (UUC). Patients with simultaneous bilateral ureteral calculi (SBUC) represent a potential urological emergency due to possible anuria and/or electrolyte imbalance. While conventional practice mandates immediate intervention in these patients, little data exist to define the rate of these events. METHODS: Records of all patients with ureteral stones treated ureteroscopically over an 11-year period were reviewed to identify those with SBUC.
CONCLUSION: Radiotherapy is effective treatment in advance vaginal adenocarcinoma, however, with high morbidity. The authors advise rigorous gynecologic exams in young females with renal agenesis as there may be a risk of malignant changes in vagina. PMID: 29767889 [PubMed - in process]
CONCLUSIONS: FHL2 is involved in renal interstitial fibrosis by altering the phenotype of renal tubular epithelial cells via regulating the β-catenin pathway. PMID: 29771425 [PubMed - in process]
Conclusion ECL is effective in the management of the calculi of the upper urinary tract however; its results can still be improved.
