Ureteral Stump Empyema With Calculi
Publication date: Available online 17 October 2019Source: Urology Case ReportsAuthor(s): Walid Smeoui, Ahmed Samet, Talel Touaiti, Nouri Rebai, Abderrazek Bouzouita, Mourad HadjslimèneAbstractA 52-year-old man with a history of right nephrectomy for a nonfunctioning kidney, consults after 22 years for fever with right lower abdominal pain. Surgical exploration was thereafter performed and the right ureteral stump was removed en bloc. Pathological examination of the right ureterectomy specimen revealed a significant acute and chronic ureteritis due to stone without any signs of malignancy. Owing to the low incidence of complications associated with ureteral stump, we suggest that if ureteral remnant becomes symptomatic, a distal ureterectomy should be performed without any delay avoiding subsequent complications of the stump.

Conclusions: MSC therapies in the treatment of knee OA are safe and have shown promising results but the available studies are limited. At this time, no definitive recommendations can be made regarding which MSC source to use. Allogeneic MSCs offer theoretical advantages over autologous MSCs, especially in ease of use and consistency of product, but there are concerns regarding cell viability and vitality, as well as the body’s response to nonautologous products. Future clinical trials should focus on randomized head-to-head comparisons of MSC sources as well as the use of multiple injections for patients with knee OA.
Low back pain and neck pain are the first and fourth leading causes, respectively, of years lived with disability. The treatment of intervertebral disk degeneration remains a significant challenge. While there are still many obstacles to overcome, the use of stem cells for the treatment of disk degeneration has emerged as one of the most promising and exciting techniques to restore the structure and function of the degenerated disk. The use of stem cells in treating intervertebral disk disease as well as the obstacles that remain are reviewed here in an evidence-based manner.
Conclusion. Anxiety and mood are potentially modifiable risk factors that have the greatest impact on pre- and postoperative pain. These results can be used to identify higher-risk patients and develop preoperative therapeutic protocols to improve postoperative outcomes. Level of Evidence: 3
We report the case of a 70-year-old female patient who presented with flank pain, pyuria, fever, and a unilateral nonfunctioning kidney with nephrolithiasis and pyonephrosis on pyelography. Routine imaging failed to identify a mass lesion. In an Indian setting, the clinical differential of tuberculosis was considered likely. A nephrectomy was performed in view of the poor perfusion and functional status of the right kidney. Histopathological examination of the kidney showed a tumor of urothelial origin arising at the renal pelvis displaying extensive squamous metaplasia. Such a near total metaplastic change is rare and has...

Yadav, Hema Udawat, Shivam Priyadarshi, Nachiket Vyas, Neeraj Agarwal Primary squamous cell carcinoma (SCC) of renal pelvis is a rare neoplasm. A 75-year old male presented with history of chronic dull aching pain in left flank region for last 10-years with history of left pyelolithotomy about 30-years back. After proper workup, large calculus with heterogeneous density mass detected in nonfunctioning left kidney. After radical nephrectomy, histopathological examination revealed squamous cell carcin...
