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...

The use of double J catheters is usual in urologist's daily practice. The indication can be divided in prophylactic or therapeutic. Prophylactically, they prevent complications derived from endourological procedures, such as ureteral lesion or obstructive uropathy secondary to residual lithiasis or edema. Therapeutically, they treat obstructive uropathy of many different pathologies, either in an emergency setting or scheduled, such as lithiasis, stenosis, extrinsic compression of any nature or urinary tract tumors among others...

Background: Ureteral stenosis is part of the common complications of renal graft reported in 3% to 7% of cases. Multiple treatments have been introduced regarding length and position of the stenosis. Metal stents for urologic purpose were created in 1998. Double percutaneous antegrade and transurethral retrograde access to a ureteral stenosis to a long-term metal stent procedure has been rarely described. Case Presentation: Here, we present a case of a ureteral stricture in a double ipsilateral kidney graft with a common ureter...

Diffuse large B-cell lymphoma (DLBCL) is a subtype of non-Hodgkin lymphoma occurring in various sites, but rarely involving the ureters. Primary DLBCL is a rare entity. Imaging studies in a 82-year-old male patient revealed left hydronephrosis and an area of nodular soft tissue density in the upper ureteral wall. On enhanced computed tomography scans, the lesion exhibited early enhancement. As the lesion was considered to be malignant, a left nephroureterectomy was performed for the purpose of pathological diagnosis...

BACKGROUND: Flexible ureteroscopic lithotripsy (URS) is rapidly becoming a first-line therapy for patients with renal and ureteral calculi. Most current medical infusion devices can only monitor infusion flow and pressure, but not renal pelvic pressure (RPP). PATIENTS AND METHODS: We designed a patented intelligent system to facilitate flexible URS that included an irrigation and suctioning platform and a ureteral access sheath (UAS) with a pressure-sensitive tip, enabling regulation of the infusion flow precisely and control of the vacuum suctioning by computerized real-time recording and monitoring of RPP...

Deep endometriosis, occurring approximately in 1% of women of reproductive age, represents the most severe form of endometriosis. It causes severe pain in the vast majority of affected women and it can affect the bowel and the urinary tract. Hormonal treatment of deep endometriosis with progestins, such as norethindrone acetate or dienogest, or estroprogestins is effective in relieving pain in more than 90% of women at one year follow up. Progestins and estroprogestins can be safely administered in the long-term, may be not expensive and are usually well tolerated...

Background. Ureteric stent insertion during kidney transplantation reduces the incidence of major urological complications (MUCs). We evaluated whether routine poststent removal graft ultrasonography (PSRGU) was useful in detecting MUCs before they became clinically or biochemically apparent. Methods. A retrospective analysis was undertaken of clinical outcomes following elective stent removals from adult single renal transplant recipients (sRTRs) at our centre between 1 January 2011 and 31 December 2013. Results...

An 8-month-old neutered male ferret was presented for vaccination and preventive treatment for adrenal gland disease. Abdominal ultrasound revealed severe bilateral hydronephrosis and hydroureter. Excretory urography and negative contrast cystography showed bilateral ureterovesical junction stenosis. Positive retrograde cystography demonstrated right ureteral reflux. A subcutaneous ureteral bypass was placed in the left kidney; however, it had to be removed 3 months later due to an obstruction and persistent urinary tract infection...

Renal colic (RC) represents nearly 2% of emergency department admissions. RC is defined by the occurrence of back pain which may radiate towards the abdomen and external genitals. In adults, the obstruction is caused by a urinary stone in 80% of cases. The 20 % of non-stone related RCs are due either to an intrinsic obstruction (pyeloureteral junction stenosis, ureteral tumor, ...) or an extrinsic compression (pelvic tumor, lymphadenopathy ...). In over 90% of cases, an RC does not require hospitalization and is treated with medication...

OBJECTIVE: The aim of this experimental study was to evaluate the feasibility of a bilateral Boari flap bridge as a novel method for unilateral long-segment ureteral reconstruction. MATERIALS AND METHODS: The study was conducted on eight dogs. After resection of 10 cm of right-sided distal ureter, bilateral Boari flaps were made from the anterior upper wall of the bladder and then anastomosed head to head, forming a flap bridge. The left base of the flap bridge was transected, and the free end was then anastomosed to the proximal stump of the ureter with a stent inside...
