A 41-year-old woman with autosomal dominant polycystic kidney disease had chronic kidney disease class IV. She presented 10 days postpartum with a 4-day history of severe hematuria, left flank pain, and anemia, hemoglobin 62 g/L. CT scan showed massively enlarged kidneys with multiple cysts; several cysts bilaterally had high attenuation consistent with hemorrhage. Hematuria persisted over seve...

OBJECTIVE To report a case of severe hemorrhagic cystitis successfully treated by bilateral percutaneous nephrostomy. METHODS The case of a 67-year-old female patient who had monosymptomatic gross hematuria with clots is reported. RESULTS Standard conservative treatments failed and the patient developed a clot-retention plugged bladder. Endoscopic evacuation and electrocoagulation of bleedi...

A 71-year-old woman who had undergone a total abdominal hysterectomy and pelvic irradiation for cervical cancer and fecal diversion for adhesive ileus was referred to us for a "left" ureteral stone and intermittent gross hematuria. Bilateral ureteral stents had been indwelled because of lower ureteral strictures for a long time. Hematuria continued after the removal of the ureteral stone, and s...

Loin pain hematuria syndrome (LPHS), first described in 1967, is a disorder of chronic, severe flank pain without an identifiable source. Patients suffer from extreme unilateral or bilateral flank pain accompanied bymicroscopic or gross hematuria.1 The etiology behind this syndrome remains unclear. Pathophysiologic mechanisms of LPHS include immune hypersensitivity, abnormal glomerular basement...

We evaluated the availability of NMP22 for the diagnosis of urothelial cancer. Of 154 patients with gross hematuria or microscopic hematuria, 14 patients with bladder cancer and 4 patients with upper urothelial cancer were detected. Of 73 patients continued to be followed for urothelial cancers, 11 patients with bladder cancer were detected. NMP22 was not available when a large number of RBC wa...

We examined the relationship between microscopic hematuria and inferior vena cava (IVC) reflux. Transabdominal color Doppler ultrasonography of the IVC was performed in the supine position with the convex probe positioned perpendicular to the upper abdominal wall, and the extent of reflux into the IVC with each heart beat was examined near the diaphragm. A total of 171 patients were studied who...

To investigate the long-term outcome of the frequency-dysuria syndrome (FDS) with hypercalciuria (HCU), 19 children (15 girls and 4 boys; age range 15 months to 10 years) who presented with FDS alone (N=9) or with other associated clinical features (N=10; 6 with gross hematuria, 3 with microscopic hematuria and 1 with abdominal pain) were followed-up over 720 patient-months. Calcium loading tes...
