Digital ureteroscopic visualization of lesions responsible for chronic unilateral hematuria, so‐called idiopathic renal bleeding

Ureteroscopic Diagnosis and Povidone Iodine Treatment for Chronic Unilateral Hematuria Caused by Benign Lesions

“…In patients with typical endoscopic manifestation of a minute venous rapture in our study, a stream of blood from the tip of the renal papilla or fornix was identified. Peripapillary varices appeared as a tortuous vein over the papilla [ 10 ]. Two patients with diffuse lesions showed extensive congestion and edema of mucosa or multiple erosion of mucous membranes in the renal pelvis and calyces.…”

Development of Endoscopic Diagnosis and Treatment for Chronic Unilateral Hematuria: 35 Years Experience

“…We found 15 pertinent articles including 288 cases of CUH in PubMed database. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] Endoscopically, CUH can be classified into three categories: discrete lesion, diffuse lesion, or no (unidentified) lesion (Table 1).…”

“…They inserted the FU through a ureteral access sheath and systematically evaluated the upper urinary tract. 15 Latest models using tiny complementary metal-oxide-semiconductor (CMOS) chip are 8.5F of shaft and tip diameter so that digital ureteroscopy is more useful for the diagnosis and treatment of CUH. As ureteroscopic devices have been miniaturized and developed more precise endoscopic techniques have been established.…”

Percutaneous Transcatheter Embolisation of the Renal Artery for Chronic Unilateral Haematuria

“…1,3,5 The use of digital flexible ureteroscopy has enabled easier diagnosis and treatment, and chronic unilateral haematuria is no longer an 'idiopathic' disease. 7 Most cases of chronic unilateral haematuria have a microscopic pathophysiology, and a definitive diagnosis cannot be made through standard radiological studies such as intravenous pyelography, retrograde pyelography, renal ultrasonography, renal CT, renal angiography, or renal magnetic resonance imaging. 5,6,8 Cystoscopy can reveal the haematuria to be supravesical in origin from one or both ureteral orifices.…”
