Iris, a recently introduced segmentation software, generates interactive three-dimensional virtual models to aid preoperative surgical planning and intraoperative navigat...
Chapter
Partial cystectomy is an option when considering bladder preservation in the management of a solitary bladder tumor and may be performed in conjunction with pelvic lymphadenectomy. Multifocal disease is a contraindication to partial cystectomy. Bladder diverticulectomy can be performed for oncological causes or in the setting of benign disease. The...
Chapter
The surgical management for ureteropelvic junction obstruction (UPJ) has evolved over the past few years. We have seen significant changes in the treatment paradigm for this condition. While initially the only treatment option was an open surgical approach, the past few decades have shown an evolution toward less-invasive therapies. Laparoscopic py...

Nephrogenic adenomas are rare benign lesions of the urinary tract occurring most frequently in the bladder of male patients. We report the case of a female patient presenting with gross hematuria, which lateralized to the left ureter on cystoscopy. At the time of ureteroscopy, two polypoid lesions were identified in an upper and lower pole calyx, w...
