PURPOSE To evaluate the prevalence and type of rigid ureteroscopy complications and suggest a new method for ureteral avulsion prevention. MATERIALS AND METHODS Between March 2002 and March 2009, we retrospectively evaluated 2955 patients who had undergone diagnostic or therapeutic ureteroscopy for asymptomatic hematuria, migrated ureteral stent, or transurethral lithotripsy. They were enroll...

Background: Complete colonic duplication is a very rare congenital anomaly that may have different presentations according to its location and size. Complete colonic duplication can occur in 15% of gastrointestinal duplication. We report two cases of complete colonic duplications, and their characteristics. Case Presentation: We present two patients with complete colonic duplication with differ...

71 Ureteral Obstruction IntRoduCtIon The ureters are fibromuscular ducts carrying urine from the kidney to the urinary bladder by peristaltic activity, which is transmitted from one muscle cell to the next (1). The ureters originate in the renal pelvices and travel retroperitoneally along the aorta and vena cava towards the urinary bladder. Near the pelvis they join the lateral ligament of the ...

Caudal duplication (dipygus) is an uncommon pathologic of conjoined twinning. The conjoined malformation is classified according to the nature and site of the union. We report the presence of this malformation in a female crossbreed puppy. The puppy was delivered by caesarean section following a prolonged period of dystocia. External findings showed a single head (monocephalus) and a normal cra...

BACKGROUND Recent studies on Vietnamese children have shown that kidney diseases are not detected early enough to prevent chronic renal failure. The dipstick test is a simple and useful tool for detecting urinary abnormalities, especially in isolated or remote areas of Vietnam, where children have limited access to health care. METHODS This cross-sectional study was conducted in 2011 at seven...

conclusions: administration of α-1a-specific blocker reduced analgesic dosage and colic episodes and rate of adverse effects after ureteroscopic lithotripsy of lower ureteral stones and decreased gravel expulsion time after ursl. results: the results showed that tamsulosin treatment group had low expulsion time (p = 0.011), low urinary tract symptoms, least analgesic needs and low adverse effec...

BACKGROUND AND PURPOSE Intraluminal application of pharmacologic agents for acute ureteral dilation may facilitate difficult ureteroscopy. We characterized the in-vivo effects of intraluminal application of verapamil and theophylline on ureteral peristalsis and diameter in a porcine model. MATERIALS AND METHODS Twenty-four female domestic pigs (35-40 kg) were incorporated into the study. We d...

Caudal duplication is an abnormality which usually affects the digestive, urogenital and even respiratory systems. It forms a graded series from slight duplication to near separation of two fetuses caudocranially. In some conjoined twins, duplication process may cranially proceed up to the head region. This kind of developed conjoined monocephalus twin has been reported in many domestic species...

results a total of 529 patients underwent kidney transplant surgery in our center. urologic complications among the three groups consisting of hydronephrosis, urinoma and collection did not have statistically significant differences. conclusions ureteral stent can be picked up with no increased risk of urologic complications at shorter intervals after the kidney transplantation surgery. patient...

OBJECTIVE Ureteral obstruction is one of the complications of testicular tumor with retroperitoneal lymph node metastasis that requires ureteral stenting for management. We elucidated the clinical courses of ureteral obstructions and changes in renal functions in patients with indwelling ureteral stenting. METHODS The medical records of 56 patients who were treated for metastatic testicular t...
