  • Pyocalycosis: a report of two cases of complicated hydrocalycosis. [Case Reports]
    Urol Int. 2014; 92(1):119-21.Taşkınlar H, Avlan D, … Naycı A
  • Hydrocalycosis is defined as cystic dilatation of a major calyx with a demonstrable connection to the renal pelvis and an epithelial lining of the cyst wall. Although this condition has long been known, there are no sufficient data concerning this pathology in the literature. In this study, we present two complicated hydrocalycosis--'pyocalycosis'--and discussed the therapeutic approaches.
  • Percutaneous nephroscopic surgery. [Journal Article]
    Korean J Urol. 2010 May; 51(5):298-307.Hwang TK
  • With the development of techniques for percutaneous access and equipment to disintegrate calculi, percutaneous nephroscopic surgery is currently used by many urologists and is the procedure of choice for the removal of large renal calculi and the management of diverticula, intrarenal strictures, and urothelial cancer. Although it is more invasive than shock wave lithotripsy and retrograde uretero…
  • Posterior Urethral Valves with Severe Unilateral Vesicoureteral Reflux in a 3-year-old Boy. [Case Reports]
    Ann Ib Postgrad Med. 2007 Dec; 5(2):73-6.Godwin OI, Ayotunde OO
  • In patients with posterior urethral valves (PUV), severe unilateral vesicoureteral reflux (VUR) is one of the three conditions associated with preservation of renal function. Others are urinary ascites or urinoma in newborns and large congenital bladder diverticula. These conditions most likely provide a pop-off mechanism preventing the development of high intravesical pressure. Only 5% of patien…
  • Renal hypertrophic infundibular stenosis. [Case Reports]
    Fetal Pediatr Pathol. 2004 Jul-Aug; 23(4):285-92.Craver R, Boyd R, … Harmon E
  • Bilateral hydrocalycosis secondary to radiographically demonstrated bilateral infundibular stenosis required a left nephrectomy in an 18-year-old young man. The infundibular narrowing was due to marked hyperplasia of the submucosal smooth muscle. Scattered within the hypertrophic smooth muscle were rare spindled CD117-positive interstitial cells, similar to the cells responsible for peristaltic p…
  • A new cause of curvilinear renal calcification: calcified hydrocalycosis. [Case Reports]
    Eur J Radiol. 2000 Oct; 36(1):16-9.Atakan IH, Pekindil G, … Inci O
  • Although many causes of curvilinear renal calcifications have been described, calcified hydrocalycosis mimicking hydatid cyst has not previously been reported. We report a case of hydrocalycosis which was appeared as a curvilinear calcified cystic lesion resulted from staghorn calculus associated with xanthogranolomatous pyelonephritis (XGPN) on intravenous pyelography (IVU) and computed tomograp…
  • Circulating adhesion molecules and neutral endopeptidase enzymuria in patients with urolithiasis and hydronephrosis. [Journal Article]
    Urology. 2000 Jun; 55(6):961-5.Huang H, Chen J, Chen C
  • CONCLUSIONS: Serum levels of ICAM-1 were elevated in patients with unilateral hydronephrosis caused by a ureteral stone, and E-selectin and L-selectin levels did not change significantly. These findings suggest that ICAM-1 may play a role in renal immune injury to ureteral obstruction. The urinary NEP values were lower in patients with hydronephrosis caused by ureteral stones, and the traditional lysosomal enzymes were increased. The lower urinary NEP values might suggest impairment of ipsilateral renal function. Renal stones per se resulted in no significant changes in serum adhesion molecule levels, although the levels of L-selectin were significantly decreased.
  • [Ultrasonic echography in the diagnosis of urolithiasis]. [Case Reports]
    Vestn Rentgenol Radiol. 1991 Jul-AugSipukhin IaM, Kilin SD, … Kilina LV
  • The paper is concerned with comparison of the results of ultrasound and x-ray investigation in 110 patients with urolithiasis. A possibility was established to diagnose roentgenonegative concrements in the kidneys and pelvicalyceal system with the help of ultrasound echography. The results of x-ray investigation were more reliable for the localization of uretero- and cystoliths. Ultrasound echogr…
  • Staged ESWL monotherapy of complete renal staghorn calculi. [Journal Article]
    J Formos Med Assoc. 1991 Jan; 90(1):48-52.Chen J, Hsu TC
  • A retrospective study was done on 64 patients who received staged extracorporeal shock wave lithotripsy (ESWL) monotherapy for complete renal staghorn calculi. We used laboratory-proven stone components and a regular postoperative follow-up for a minimum of 6 months. There were 46 women and 18 men. The ages ranged from 19 to 75 years (mean 48.5 years). The number of ESWL sessions ranged from 1 to…
  • [Remote lithotripsy with the URAT-P apparatus in treating urolithiasis in children]. [Journal Article]
    Urol Nefrol (Mosk). 1990 May-JunLopatkin NA, Dzeranov NK, … Martov AG
  • The Soviet-made device "URAT-P" for remote lithotripsy was used for the treatment of urolithiasis in children aged from 22 months to 14 years who suffered from various clinical patterns of urolithiasis with solitary or dendritic calculi. Out of 64 treated persons, 21 children had undergone 1-2 surgeries for the disease. The majority of them had pains and frequent aggravations of pyelonephritis. E…
  • Infundibulopelvic dysgenesis: a spectrum of obstructive renal disease. [Journal Article]
    Urology. 1990 Apr; 35(4):334-7.Uhlenhuth E, Amin M, … Howerton LW
  • Infundibulopelvic dysgenesis is an obstructive process of the pyelocalyceal system that is responsible for a spectrum of congenital renal disorders. The site and degree of narrowing in the infundibulopelvic system produce the various congenital anomalies like hydrocalycosis, calyceal diverticula, ureteropelvic junction stenosis, and multicystic kidney. A classification with illustrative cases is …
  • [7 cases of congenital multicystic kidney with special reference to its embryogenesis]. [Journal Article]
    Hinyokika Kiyo. 1984 Sep; 30(9):1231-7.Shinno Y, Gotoh T, … Terashima M
  • We have experienced 7 cases of multicystic kidney. The latest two cases, etiologically of interest, are reported herein with special reference to its embryogenesis. Case 6: A 4-year-old girl was referred to our clinic for further evaluation of mild azotemia and nonvisualization of left kidney. Left kidney was strongly thought to be multicystic kidney from abdominal CT, whereas her contralateral k…
  • Computed tomography in the diagnosis of renal parapelvic cysts. [Journal Article]
    J Comput Assist Tomogr. 1983 Oct; 7(5):833-6.Morag B, Rubinstein ZJ, … Solomon A
  • The appearances of 34 parapelvic cysts diagnosed by computed tomography (CT) in 29 patients are described. The majority were found as an incidental finding but some caused hydrocalycosis and, in one instance, hypertension. Their etiology, CT features, and differential diagnosis are discussed. The specificity of CT in these cases eliminates the need for invasive diagnostic procedures.
  • Hydrocalycosis. A report of two cases. [Case Reports]
    Radiologe. 1980 Dec; 20(12):596-9.Spigos DG, Zaitoon MM, … Sassoon H
  • Hydrocalycosis is the progressive cystic dilatation of a major calyx due to infundibular obstruction. Two cases of hydrocalycosis are herein presented and several diagnostic procedures are discussed. A correct diagnosis can be made by proper use of newer radiographic techniques. Treatment depends upon the etiological and complicating factors.
