We present a 60 years old male with transitional cell carcinoma of the left ureter. The right kidney was non excretory while the left one was the solitary functioning kidney with multiple renal cysts. He had presented with significantly deranged renal profile and left obstructed ureter. The ureterorenoscope could not be negotiated so exploration of the left ureter was done. This showed a growth in left ureter, confirmed as transitional cell carcinoma (TCC) on histopathology. Subsequently excision of the distal left ureter along with the tumour and the cuff of bladder (segmental ureterectomy) was contemplated. Proximally transureteroureterostomy was performed. Postoperative recovery was smooth and the renal profile became normal within 3 months.

Ureteral papillary carcinoma is a rare subtype of urothelial carcinoma, ranking fourth among cancers following prostate (or breast) cancer, lung cancer, and colorectal cancer. Although previous studies have documented bone metastases mainly in the pelvis, spine, ribs, and femur, this case report presents the first recorded instance of metastasis occurring in the acromioclavicular joint. A 62-year-old woman with a history of left flank pain and macroscopic hematuria underwent a left nephroureterectomy, which revealed ureteral papillary carcinoma.

The literature regarding robotic-assisted radical cystectomy in kidney transplant recipients is limited. We present the first reported case of robotic-assisted radical cystectomy with a full intracorporeal orthotopic neobladder in a kidney transplant recipient. A 36-year-old man was diagnosed with muscle-invasive urothelial carcinoma 12 years after kidney transplantation.

Objective:  The pyeloureteral anastomosis remains the most challenging part of pyeloplasty. A purpose-built anastomotic device could simplify this step and potentially improve outcomes. The concept of a pyeloureteral magnetic anastomosis device (PUMA) was proven in minipigs, but only in short term.

Objectives: To evaluate the at-risk organs that require protection during percutaneous cryoablation (PCA) of renal tumours and the correlation with patient and target lesion characteristics, type of protective measure used and postoperative outcomes.

Materials And Methods: Single-centre retrospective review of patients with renal tumours who underwent PCA between 2008 and 2020. Final analysis included 374 tumours.

A 14-year-old boy developed hydronephrosis and worsening renal function due to fibroepithelial polyps of the bladder and left ureter at the age of 12 years. The endoscopic treatment of ureteral polyps was attempted by his previous doctor; however urethral stricture and ureteral stricture developed and was untreatable. Therefore, he was referred to our hospital for further reconstructive treatment.
