Robot-assisted extravascular stent for nutcracker syndrome: A case report.

Nutcracker syndrome (NCS) is a rare condition caused by compression of the left renal vein (LRV) between the aorta and superior mesenteric artery. Surgical treatment is reserved for patients with severe symptoms and failure of conservative treatment. A 31-year-old woman diagnosed in adolescence with NCS has had recurrent pain since age 15.

Recommendations on robotic-assisted radical prostatectomy: a Brazilian experts' consensus.

Radical prostatectomy is a commonly adopted treatment for localized/locally advanced prostate cancer in men with a life expectancy of ten years or more. Robotic-assisted radical prostatectomy (RARP) is comparable to open radical prostatectomy on cancer control and complication rates; however, new evidence suggests that RARP may have better functional outcomes, especially with respect to urinary incontinence and erectile dysfunction. Some of the surgical steps of RARP are not adequately described in published literature and, as such, may have an impact on the final outcomes of the procedure.

Robotic-assisted excision of a prostatic utricle cyst in a 12-month boy with proximal hypospadia and 45X0/ 46XY karyotype.

Introduction: Prostatic utricle cysts result from incomplete regression of Mullerian duct structures and occur most frequently in males with perineal or peno-scrotal hypospadias. Utricular cysts may present with various signs and symptoms including urinary tract infection, pain and post-void incontinence, a palpable abdominal mass or recurrent epididymitis.

Material And Methods: We present a 12 months boy we treated due to proximal hypospadias in two stages, in association to a dysplastic undescended testis that was excised.

Diode Laser Vaporization for Benign Prostate Hyperplasia: Outcome After 126 Procedures.

Photoselective vaporization of the prostate (PVP) with a 940-nm diode laser is an option for treating symptoms caused by benign prostatic hyperplasia (BPH). Here, we present our experience using this technology. We prospectively evaluated 126 patients with lower urinary tract symptoms (LUTS) secondary to BPH who underwent PVP with a 940-nm diode laser from January 2011 to January 2014.

Robot-Assisted Infratrigonal Vesicovaginal Fistula Repair.

Background: Although relatively rare, vesicovaginal fistula is the most common genitourinary fistula, causing a significant decrease in patients' quality of life. Location of fistula is major supratrigonal, with some cases located in the trigone and rarely below it. Disease treatment is surgical, and repair can be performed by several techniques, including robot-assisted.

Giant Perineal Solitary Fibrous Tumor: A Rare Case Report.

. Solitary fibrous tumor (SFT) is a fibroblastic mesenchymal tumor that was initially described from the pleura but currently arises at almost every anatomic site. It is usually benign, and surgical resection is curative.

Two Cases of Solitary Fibrous Tumor Involving Urinary Bladder and a Review of the Literature.

Solitary fibrous tumor (SFT) is a rare neoplasia of mesenchymal origin, initially described in visceral pleura and lately discovered to have ubiquitous distribution. SFT of the urogenital tract is uncommon and appears to have similar morphologic features and biologic behaviors as SFTs found elsewhere. We present two new cases of SFT of the bladder and review 22 similar cases published in the literature.

Reduction in Renal Specimen After Laparoscopic Radical Nephrectomy: A Histopathologic Analysis.

Abstract Background and Purpose: There is no consensus on the most appropriate way to extract the kidney after laparoscopy. A previous study evaluated the reduction in total kidney volume and incision size (40%) after perfusion with a 5% hypertonic solution in a porcine model. The purpose of the current study was to compare the histopathologic renal tumor diagnosis before and after this perfusion.

Pseudomyxoma peritonei associated with primary mucinous borderline tumor of the renal pelvicalyceal system.

Primary mucinous cystic neoplasms are extraordinarily rare tumors of the kidney. Herein, we present a case of a 52-year-old man who presented with painless hematuria and mucusuria. The nephrectomy showed a markedly enlarged kidney replaced by a large cystic mass filled with mucin and with almost complete destruction of the renal parenchyma.

In-vitro renal shrinkage after hypertonic saline perfusion for organ removal during laparoscopic nephrectomy.

Background And Purpose: To evaluate the possibility of shrinking the kidney by perfusion with hypertonic solution to facilitate organ removal in laparoscopic surgery.

Materials And Methods: After 18 open nephrectomies (ONs) in 9 pigs, one of four saline solutions (5%, 7.5%, 10%, and 15%) was infused through a catheter into the renal artery for 5 minutes in four kidneys each.
