Long segment ureterectomy with tapered demucosalized ileum replacement of ureter for ureteral cancer: a case report and literature review.

Radical nephroureterectomy (RNU) with bladder sleeve resection is currently the gold standard for the treatment of high-risk ureteral cancer. However, in certain special cases, such as bilateral upper tract urothelial carcinoma(UTUC), isolated and chronic kidney disease, and low-risk UTUC, kidney sparing surgery(KSS) may represent a viable alternative, though it remains highly challenging. The current KSS options for ureteral cancer include endoscopic treatment, segmental ureterectomy, total ureterectomy combined with kidney autotransplantation and nephrostomy.

Advanced prostate cancer diagnosed by bone metastasis biopsy immediately after initial negative prostate biopsy: a case report and literature review.

Prostate cancer (PCa) is a prevalent male malignancy that originates in the epithelial cells of the prostate. In terms of incidence and mortality of malignant tumors in men, PCa ranks second and fifth globally and first and third among men in Europe and the United States, respectively. These figures have gradually increased in recent years.

Renal cell carcinoma associated with Xp11.2 translocation/transcription factor E3 gene fusion: A case report and literature review.

Renal cell carcinoma (RCC) associated with Xp11.2 translocation/transcription factor E3 (TFE3) gene fusion is a rare subtype of RCC. A 31-year-old male patient was admitted to The Affiliated Hospital of Zunyi Medical University (Zunyi, China) with a solid mass in the left kidney during a routine health examination.

Knockdown of inhibits Akt/β-catenin-mediated cell invasion and migration in clear cell renal cell carcinoma cells.

The gene encoding lamin A/C is amplified in some clear cell renal cell carcinoma (ccRCC) samples. Our data showed that depletion of the tumor suppressor PBRM1 can upregulate lamin A/C levels, and lamin A/C could interact with PBRM1. However, the role of lamin A/C in ccRCC is not yet fully understood.

Analysis of uroseptic shock after ureteroscopy for ureteral calculi during pregnancy: a case report.

Background: Uroseptic shock secondary to ureteral calculi during pregnancy is rare. It is characterized by rapid onset, rapid progression, aggressive disease, limited treatment, poor prognosis, and a mortality rate higher than 20% with improper or delayed management. A clear diagnosis is made based on typical clinical symptoms and abdominal ultrasound, often requiring combined multidisciplinary treatment and the simultaneous release of the obstruction.

Feasibility study on epithelial cells regeneration after excising the demucosalized ileum for ureteral reconstructive surgery.

This study aimed to investigate the regeneration of epithelial cells in the long-term observation of ureter reconstruction by excising the demucosalized ileum. First, 8 Beagle dogs were anesthetized and the abdominal cavity was inspected for abnormalities via an abdominal incision. The right kidney and ureter were subsequently separated, and the ureter was severed from its connection to the renal pelvis and bladder and ligated distally.

Well‑differentiated neuroendocrine tumor of the right kidney: A case report.

Neuroendocrine tumors (NETs) are tumors originating from neuroendocrine cells and peptidergic neurons. Primary renal well-differentiated NETs (WDNETs) are rare and only sporadic cases have been reported worldwide. In November 2021, a 45-year-old female patient was admitted to The Affiliated Hospital of Zunyi Medical University (Zunyi, China) with right-sided lumbago.

Replacement of long-segment ureteral defect with tapered demucosalized ileum: medium-term outcomes of 4 patients.

Purpose: Repair of long-segment ureteral defect (LSUD) is challenging. Currently available procedures carry some potential complications. We modified the ileal graft by tapering the wall and stripping the mucosa to combat associated pitfalls and first reported the medium-term outcomes of 4 patients.

Hem-o-Lok clip migration into renal pelvis and stone formation as a long-term complication following laparoscopic pyelolithotomy: a case report and literature review.

Background: Hem-o-Lok clips (HOLCs) are widely used in minimal access urological operations due to the advantage of vascular control and suture stabilization. In rare cases, however, they can develop problems themselves. Migration of HOLCs into the collecting system is a fairly rare complication after laparoscopic pyelolithotomy.

Endovascular Treatment Failure of Renal Arteriovenous Malformation due to an Extrarenal Feeding Artery: A Case Report.

Renal arteriovenous malformation (RAVM) is a rare pathology. It may present with heamturia, hypertension, and congestive heart failure. Digital subtraction angiography (DSA) is the standard diagnostic choice, and endovascular embolization is a preferred procedure of management in most cases.

Renal Urothelial Carcinoma Complicated by Inferior Vena Cava Tumor Thrombus and Acute Pyelonephritis.

Renal urothelial carcinoma (UC) with inferior vena cava tumor thrombus is rare, especially when it is concomitant with acute pyelonephritis. In this report, a 70-year-old diabetic man with right flank pain, intermittent painless gross hematuria, and recurrent high fever was described. On the basis of the symptoms, physical examination, cytology and imaging results, renal UC with extension into inferior vena cava, and acute pyelonephritis was established.

Improved Long Ureteral Reconstruction With Ileum By Longitudinal Clipping And Mucosal Stripping: An Animal Study.

Purpose: To investigate the possibility of bridging long ureteral defects by longitudinal clipping and mucosal stripping of the pedicled segment of ileum (CMSPI).

Materials And Methods: Ten beagle dogs (five males and females aged 2-3 years) were used to model a defect of the entire ureter. An ileal segment was selected, and half of the intestinal segment was longitudinally resected, without mesenteric resection.

Bladder Outlet Obstruction Induced by the Compression of Displaced Hemipelvic Prosthesis After Pelvic Reconstruction: A Case Report.

Bladder outlet obstruction (BOO) is a common urological condition usually caused by benign prostatic hyperplasia, prostate cancer, urethral stricture, rarely by compression of surrounding organs. Herein we presented a BOO patient caused by the compression of displaced hemipelvic prosthesis after pelvic reconstruction. This report may help to increase awareness of BOO as a late complication of pelvic reconstruction.

Comparison of stone dusting efficiency when using different energy settings of Holmium: YAG laser for flexible ureteroscopic lithotripsy in the treatment of upper urinary tract calculi.

Purpose: The aim of this study is to evaluate the impact of different pulse energy settings on dusting efficiency in flexible ureteroscopic lithotripsy (fURSL) for the treatment of upper urinary tract calculi.

Materials And Methods: Data of 88 consecutive patients who underwent fURSL for upper urinary tract calculi by a single surgeon in our department From August 2017 to August 2018 were reviewed retrospectively. Lumenis Power Suite 100W lithotripter with a 200 ?m laser fiber was used to comminute stones.

Intramuscular nerve distribution in bladder and the relationship between intramuscular ganglia and bladder function in man and dog.

In clinical, the relationship between bladder intramuscular nerve and function is also elusive. This study aims to compare the bladder intramuscular nerve distribution and its characteristics and significance in human and dog. Eleven dogs' bladders were stained by Sihler's and HE techniques.
