Intrathoracic kidney is a partial or complete displacement of the kidney above the hemidiaphragm into the mediastinal compartment of the thorax. It is usually seen as an incidental finding discovered on chest radiograph or abdominal ultrasound. However computed tomography consents the correct detection of intrathoracic masses and defines their shape, size, and extent. We here report a case of ectopic thoracic kidney in a 22-year-old man who had a long history of scrotal discomfort associated with right varicocele...

Ureteral cancer in the retrocaval ureter is rare. We herein report a patient with this condition laparoscopically treated. A 69-year-old man was referred to us because of right ureteral cancer diagnosed during ureteroscopic surgery for a ureteral calculus. Histological diagnosis of the ureteroscopically biopsied material was non-invasive papillary urothelial carcinoma, low grade (G2). Computed tomography (CT) demonstrated a retrocaval ureter : a double J stent placed during ureteroscopy assisted the diagnosis...

OBJECTIVES: The purpose is to determine the effects in urinary tract of a new antireflux biodegradable ureteral stent. MATERIAL AND METHODS: Thirty six ureters belonging to 24 pigs were used. The study began with an endoscopic, nephrosonographic and fluoroscopic assessment. Three study groups of n=12 ureters were then specified. In Group I, a biodegradable antireflux stent (BDG-ARS) was inserted in the right ureter of 12 pigs. Group II was comprised by the left ureter of the same animals, in which a double pigtail stent was placed for 6 weeks...

Suprapubic cystostomy is a widely employed procedure that is used to drain the bladder. Despite being a safe procedure, suprapubic cystostomy has been reported to present multiple intra- and postoperative complications. Serious and unusual complications can occur during changing of the suprapubic catheter (SPC) in patients with neuropathic bladder. In this work, we report an elderly patient with neuropathic bladder suffering from an unusual complication involving migration of the SPC into the ureter during changing of the SPC, leading to ureteric obstruction and left pyelonephritis...

A 74-year-old male patient with prostate cancer under remission was admitted with left inguinoscrotal swelling. He underwent scrotal ultrasound demonstrating a giant in-guinoscrotal hernia. Contrast-enhanced computerized tomography of the abdomen and pelvis demonstrated a left pelvic kidney associated with severe hydroureteronephrosis secondary to a ureteral inguinoscrotal hernia. Upon exploration with left inguinal incision, a paraperitoneal ureteral in-guinoscrotal hernia and a hypertrophic left spermatic cord were observed...

Objective: To describe a simple, novel method to achieve ureteric access in the Cohen crossed reimplanted ureter, which will allow retrograde working access via the conventional transurethral method. Materials and Methods: Under cystoscopic vision, suprapubic needle puncture was performed. The needle was directed (bevel facing) towards the desired ureteric orifice (UO). A guidewire (with a floppy-tip) was then inserted into the suprapubic needle passing into the bladder, and then easily passed into the crossed-reimplanted UO...

Ureteral stent placement is a common procedure in urologic practice. Forgotten, encrusted D/J stents represent a difficult problem for urologists. The major complications are infection, impaired renal function, migration, encrustation, stone formation and multiple fragmentation of stent. A consensus on the best therapeutic approach is still lacking. Here we present our experience with endoscopic management of this challenging problem and discuss the multimodal endourologic approaches for treating forgotten, encrusted ureteral stents...

INTRODUCTION: Upper pole access in percutaneous nephrolithotomy (PCNL) provides a straight tract to the ureter, resulting in easier placement of a guidewire to the ureter, good exposure of the pelvis, calices, and upper ureter, and comfortable manipulations. However, despite these benefits, upper pole access is usually avoided because of the risk of chest complications in both pediatric and adult patients. OBJECTIVE: We aimed to evaluate the safety and morbidity of single upper pole access in pediatric patients undergoing PCNL...

Urolithiasis (UL, urinary tract stone disease) has been reported to increase subsequent cancers in the urinary tract. Recently, we showed data that surveillance bias may be an important confounder in the reported associations. In the present approach we want to address the question of possible cancer risk posed by UL mechanistically. Both UL and cancer have strong genetic components and we hypothesize that familial association between UL and cancer may be plausible. We thus assess familial risks between UL and cancer, hoping to find an explanation why UL may pose a risk of cancer...

CLINICAL FEATURES: Renal colic is defined as a flank pain radiating to the groin caused by kidney stones in the ureter (urolithiasis). Renal colic is a frequent cause of Emergency Department visits. Most renal colic cases present as acute distress and severe back and/or abdominal pain that require prompt treatment with analgesics. THERAPEUTIC CHALLENGE: Nonsteroidal anti-inflammatory drugs and opioids are traditionally used for renal colic in the Emergency Department...

A congenital bladder diverticulum (CBD) is caused by inherent muscular weakness instead of obstruction of the bladder outlet. The major clinical conditions are recurrent urinary tract infection (UTI) and voiding dysfunction. This report describes a 15-year-old male adolescent who developed sudden visual disturbance resulting from hypertensive retinopathy. The cause of hypertension was bilateral obstructive uropathy caused by enlarged paraureteral bladder diverticula. After the non-functioning right kidney and ureter and the bilateral diverticula were removed, the left ureter was reimplanted in the bladder...

AIM: To investigate the histopathological findings in ketamine-associated uropathy (KU) and their clinical association. METHODS: Thirty-eight KU patients had received history investigation and video urodynamic study. Twelve of them were clinically mild KU who were admitted for cystoscopic hydrodistention. The other 26 patients were severe KU who were admitted for enterocystoplasty with or without ureter reimplantation. Bladder and ureter specimens were harvested during operation, and a single pathologist reviewed all specimens under hematoxylin and eosin stain...

INTRODUCTION AND OBJECTIVES: Stone formers often have a chronic exposure to significant quantities of ionising radiation from radiological investigations and interventions. Predicting radiation exposure would allow the clinician to quantify expected cumulative radiation and find strategies to minimise exposure. We evaluated radiation exposure during ureteroscopy and laser lithotripsy (URS + LL) for a single stone episode and correlated the results to stone characteristics. METHOD: Data was collected retrospectively for all patients undergoing URS + LL in our institution over a 1 year period...

Double-J ureteral stent (DJUS) is an important therapeutic tool in endourology. There are well-known frequent complications associated with DJUS placement such as distal and proximal migration within the urinary tract. However, perforation and stent misplacement are uncommon but serious complications of this technique. We present a case of a 63-year-old man who had a misplacement of a DJUS into the inferior vena cava during an elective procedure of ureteral catheterisation. The stent placement was performed under fluoroscopic control and it seemed well positioned...

Urinary calculus is a common and recurrent condition that affects kidney function. The present study evaluated the use of digital tomosynthesis (DTS) and Kidneys-Ureters-Bladder (KUB) radiography as methods of diagnosing urinary calculi. Unenhanced multidetector computed tomography (UMDCT) was used in the diagnosis of calculi. KUB radiography and DTS procedures were conducted on patients prior to and following bowel preparation to detect kidney, ureteral and bladder calculi. Differences in diagnostic performance of KUB radiography and DTS imaging on prepared and unprepared bowel were evaluated using the χ2 test...

BACKGROUND Plasmacytoid is a rare histological variant of urothelial carcinoma (UC). Since the first reported case of plasmacytoid urothelial carcinoma (PUC), in 1991, only about 100 cases have since been reported, with most cases involving the bladder. Urothelial carcinomas of the upper urinary tract represent only 5% of urothelial cancers. To the best of our knowledge, there has only been 1 reported case of PUC of the ureter. PUC is a highly aggressive disease, with a poor prognosis. We present a rare biopsy-proven case of PUC of the ureter with retroperitoneal metastasis...

Morphological and morphometric assessment of the elements of the ureterovesical junction in children was performed in the present study in different age groups ranging from 24 weeks of gestation to 16 years old. We tried to answer the question whether, in human ontogenesis, there is a period of anatomical predisposition to primary vesicoureteral reflux. The study included 210 urinary bladders with juxtavesical parts of the ureters that had been obtained from routine autopsies. As a result of the study, we showed that provided the pregnancy is uncomplicated there is no inherited susceptibility that would account for reducing or disturbing the development of ureterovesical junction elements...

OBJECTIVE: Acquiring surgical skills requires regular practice. Medical evidence supports that these skills can be learned outside the operating room (OR). The aim of the current study was to describe the first laparoscopic simulator for ureteral reimplantation (LAP-SPUR) following Lich- Gregoir technique. MATERIALS AND METHODS: LAP-SPUR was manufactured using reusable and disposable materials. The technique can be summarized in the following five steps: (1) a transperitoneal approach; (2) extra-vesical ureteral dissection; (3) detrusor division until exposing the mucosa; (4) reimplanting ureter into the new tunnel; and (5) reapproximation and suturing of the detrusor...
