Post ureteroscopic stone surgery ureteral strictures management: a retrospective study
AbstractPurposeTo share experience in managing ureteral strictures following ureteroscopic lithotripsy.MethodsNinety five patients diagnosed as ureteral strictures after ureteroscopic lithotripsy between January 2013 and January 2018 were included. 53 received endourological treatment, 34 underwent reconstruction, 6 underwent nephrectomy for severe renal impairment, and 2 chose routine ureteral stent replacement. Therapeutic success was defined as absence of clinical symptoms and radiologic relief of obstruction.ResultsThe follow-up time ranged from 13 to 57 months, with a median time of 24. It lasted more than 13 months in all patients, exception for 2 nephrectomies. Two patient groups including 69 endourological procedures and 37 reconstructions were used to compare therapeutic effects and complications. The overall success rate was 60.9% (42/69) i n endourological intervention vs. 97.3% (36/37) in reconstruction (p
Six years after living donor nephrectomy to his daughter, the 78-year-old donor presented to the emergency room with anuria for approximately 12 h. Only arterial hypertension, mildly reduced kidney function (eGFR 54 mL/min), and benign prostatic hyperplasia were known as preexisting medical conditions. In sonography, hydronephrosis III ° was visible in the right single kidney. Ureterorenoscopy revealed an occlusive tumor in the right proximal ureter, which was treated via double J stent. Biopsy showed focal invasive papillary urothelial carcinoma of G2 high grade. Preoperative staging did not show any signs of lymph no...

A 69-year-old female was admitted to our hospital for consultation on her relatively high HbA1c value. At age 20, she was diagnosed with uterus bicornis. At age 68, she was diagnosed with pancreas tail hypoplasia, renal cysts and non-functioning pancreatic neuroendocrine tumor (NE...
CONCLUSION: This study identified the expression of PDGFRα+ cells in the human UPJ. Our results demonstrate the expression of SK3 channels in PDGFRα+ cells was decreased in UPJO, and SK3 channels may be involved in the pathogenesis of UPJO by perturbing the UPJ peristalsis. .

ConclusionsLaparoscopy is a recommended option to treat CFRE, offering all advantages of this approach.
CONCLUSIONThis study demonstrated an optimal approach for relieving upper urinary tract obstruction and acute infection in which percutaneous nephrostomy drainage is preferred for patients with severe pyonephrosis, large stones (>10 mm) with high-grade hydronephrosis, steinstrasse, or failure in retrograde ureteric stent placement, while retrograde ureteral catheterization using cystoscopy is suitable for patients diagnosed with small stones (≤10 mm) and low-grade hydronephrosis.

We report a case of a young boy with a large, right-sided retroperitoneal cyst suspected as lymphangioma causing hydronephrosis. His renal pelvis was dilated, containing purulent fluid, and a nephrectomy was performed. Histopathology revealed a mature cystic teratoma of the renal pelvis.
ConclusionClinicians should be aware of the possibility of migrated hem-o-lok clips serving as a nidus for urinary tract stone formation in patients who have undergone endoscopic PN.
Conclusions: Circular enhanced musculature may cause a sphincter-like activity with holding up of urine. The higher density of neuronal expression in PUJ might be responsible for causing constant contraction and intrinsic obstruction. PMID: 30706859 [PubMed - in process]
A 10-month-old, intact male chinchilla (Chinchilla lanigera) was diagnosed with urolithiasis, unilateral hydroureter, and hydronephrosis secondary to ureteral obstruction confirmed by radiography and ultrasonography. Nephrectomy and cystotomy were performed, and the urolith was suspected to be a semen-matrix calculus (mineralized copulatory plug) based on the discovery of sperm within the renal pelvis of the nephrectomized kidney on histopathology; this was later confirmed through a post-mortem examination.
BY Dhimitri A. Nikolla, DOAn 82-year-old man with a history of dementia, multiple urinary tract infections, insulin-dependent diabetes mellitus, and an admission a month earlier for Fournier gangrene presented to the emergency department with reports of confusion and hypotension from his nursing home. His vital signs were normal, but he was disoriented with a mildly tender abdomen. His genital examination revealed a suprapubic catheter without evidence of soft tissue infection. A CT with contrast of the abdomen and pelvis revealed the images shown.What is the diagnosis? What is the treatment?The CT images demonstrate...
