OBJECTIVE: Approximately one in five patients with ureteropelvic junction stenosis (UPJS) also present with renal or ureteral stones. For patients with UPJS, the European Association of Urology guidelines currently recommend that robot-assisted pyeloplasty (RAP) and pyelolithotomy are performed as two separate procedures. The aim of the present study was to evaluate the feasibility and safety of RAP with concomitant pyelolithotomy (RAP + P) in patients diagnosed with UPJS and renal stones...

INTRODUCTION: Among urologic diseases, ureteropelvic segment stenosis with hydronephrosis is a common indication for instrumental or surgical correction. The restriction of urine flow with dilatation proximal to obstruction develops in 6.5-37% of cases at different times after the ureteral reconstruction. All this urges to develop and improve stents and search for effective ways to place stents and control their function. AIM: To investigate the effectiveness of polyhydroxyalkanoates based biodegradable stent compared with a commercial analogue in upper urinary tract drainage after ureteropelvic segment pyeloplasty...

BACKGROUND: Ureteric stenosis (US) is the most common urologic complication after kidney transplantation. In this dual-center retrospective study we compared the efficacy and safety of open surgery versus interventional radiology for the management of US. METHODS: From 2009 to January 2016, US was treated by surgical revision in 22 (7.8%) out of 281 recipients at one center (group 1) and managed by percutaneous nephrostomy with antegrade nephroureteral stenting (PNAS) in 22 (14...

BK polyomavirus (BKV) causes frequent infections during childhood and establishes persistent infections within renal tubular cells and the uroepithelium, with minimal clinical implications. However, reactivation of BKV in immunocompromised individuals following renal or hematopoietic stem cell transplantation may cause serious complications, including BKV-associated nephropathy (BKVAN), ureteric stenosis, or hemorrhagic cystitis. Implementation of more potent immunosuppression and increased posttransplant surveillance has resulted in a higher incidence of BKVAN...

Complex iliac artery obstructions, particularly bilateral stenosis or total iliac artery occlusions, are usually treated with aortofemoral or aortobifemoral graft surgery. However, surgical treatment is associated with 3% mortality rate and significant morbidity such as intestinal ischemia, spinal cord injury, and ureteral damage. Percutaneous interventions of aortic bifurcation offer a promising alternative to surgery with potentially lower morbidity and mortality risk. We report a case of peripheral artery disease who had underwent right transfemoral iliac angioplasty with femoropopliteal bypass presented again with bilateral lower limb ischemia, who was successfully treated with stent implantation with the kissing balloon technique...

OBJECTIVE: To report the long-term outcomes of ileal ureteric replacement (IUR) in complex reconstruction of the urinary tract. PATIENTS AND METHODS: From 1991 to 2016, IUR was performed in 157 patients with structural or functional ureteric loss. In 52 patients, bilateral IUR became necessary. Implantation sites where either the native urinary bladder (n = 79) or intestinal reservoirs (n = 78). In the latter group, the technique was used at the time of primary urinary diversion (n = 34), in a secondary approach (n = 29), and in undiversion or conversion procedures (n = 15)...

Hepatoblastoma is the most common primary malignant hepatic tumor of infancy and childhood, occurring predominantly in the first two years of life. The management of hepatoblastoma has changed markedly over the last 3 decades; neoadjuvant chemotherapy is now standard, particularly in unresectable tumors resulting in considerable preoperative tumor shrinkage and sometimes near total ablation of the tumor. A 20 month old infant was incidentally found to have a 7.6cm right sided retroperitoneal tumor on routine screening ultrasonography for left ureteral stenosis...

A large increase in the use of kidneys from donation after circulatory death (DCD) donors prompted us to examine the impact of donor type on the incidence of ureteric complications (UCs; ureteric stenosis, urinary leak) after kidney transplantation. We studied 1072 consecutive kidney transplants (DCD n=494, live donor [LD] n=273, donation after brain death [DBD] n=305) performed during 2008-2014. Overall, there was a low incidence of UCs after kidney transplantation (3.5%). Despite a trend toward higher incidence of UCs in DCD (n=22, 4...

Kidney transplantation is a surgical procedure involving both vascular and ureteric anastomoses. As a matter of fact, it can be performed either by urologists or vascular surgeons. However, vascular surgeon's expertise can be helpful at different times. In the present paper we describe how can vascular surgeons help at the different stages of kidney transplantation process in modern care: 1) before kidney transplantation for recipient preparation in order to allow subsequent graft implantation, either by performing percutaneous embolization of renal arteries in the setting of polycystic kidney disease or treatment of aneurysmal or occlusive lesions that would contra-indicate graft implantation; 2) at the time of surgery graft back table preparation and repair; and 3) after surgery for long-term follow-up, including transplant renal artery stenosis treatment or transplant nephrectomy...

BACKGROUND: Deletion in the chromosomal region 22q11 results from the abnormal development of the third and fourth pharyngeal pouches during embryonic life and presents an expansive phenotype with more than 180 clinical features described that involve every organ and system. HISTORY AND SIGNS: A 23-year-old African woman presented for the first trimester echography, which revealed an isolated anechoic structure suggesting a ureteral dilatation. The suspicion of a malposition of great arteries in the second trimester indicated an amniocentesis leading to a diagnosis of 22q11 deletion...

BACKGROUND: BK polyomavirus (BKPyV) infections are known indicators of immune suppression in hematopoietic stem cell transplant (HSCT) recipients; they can lead to hemorrhagic cystitis, ureteral stenosis, renal dysfunction, and prolonged hospital stays. In this study, we determined transplant-associated variables and immune parameters that can predict for the risk of BKPyV viruria. We hypothesized that BKPyV infection is a marker of poor immune recovery. METHODS: We analyzed all engrafted patients undergoing first allogeneic HSCT at MD Anderson Cancer Center in Houston between January 2004 and December 2012...

BACKGROUND: An alternative treatment for obstructive and refluxing obstructive megaureter with ureterovesical junction maintenance through laparoscopy is proposed. MATERIAL AND METHODS: The series consists of 8 cases, all of them studied because of prenatal hydronephrosis or febrile urinary tract infection. Seven were diagnosed with obstructive megaureter and one with obstructive refluxing megaureter. The procedure consisted in incising the stenotic portion of the ureter longitudinally and maintaining its posterior wall attached to the bladder, the anterior wall of the ureter was anastomosed transversally to the bladder mucosa in order to liberate the obstruction...

Mayor urological complications, fistulae and stenosis, mainly affect the vesicoureteral anastomosis and present in the early post-transplant period. The systematic use of ureteral catheters keeps selecbeing controversial with many groups using them only selectively depending on the existence of pretransplant or intraoperative risk factors. METHODS: We performed a bibliographic review through automatized search in the Medline bibliographic database, as the main bibliographic source, and also in Clinical Key...

One of the main wishes in the field of urinary catheters and stents is to arm them with biodegradable characteristics because we consider a failure of these devices the need for retrieval, the forgotten catheter syndrome as well as the adverse effects permanent devices cause after fulfilling their aim. The efforts focused in new designs, coatings and biomaterials aim to increase the biocompatibility of theses internal devices. Lately, there have been correct advances to answer the main challenges regarding biodegradable ureteral devices...
