The patient, an 18-year-old woman, visited a local doctor complaining of right flank pain. Characteristic findings obtained by X-ray examination suggested milk of calcium renal stone in the calyceal diverticulum of the right kidney, she was introduced to our clinic on February 16, 1989. Although examinations on admission showed no urinary tract obstruction or renal function disorders, since she repeatedly suffered from flank pain, we decided to remove the stone percutaneously and widen the mouth of the diverticulum. Conventional percutaneous nephrolithotripsy methods were used to endoscopically remove the stone but we were unable to ascertain the mouth of the calyceal diverticulum. Thus, we removed the nephrostomy tube. The stone was composed to 83% calcium oxalate and 17% calcium phosphate. She was released from the hospital with no particular postoperative complications and at present the flank pain has disappeared. Percutaneous treatments against milk of calcium renal stone are discussed.

Between 1972 and 1984 148 children with urolithiasis were studied and managed at the University Clinic Children's Hospital of Teheran. In 125 children the calculi were in the upper and in 23 children in the lower urinary tract. The maximum incidence was between the ages of 5-8 and 12 years. 25 children had malformations and 16 had metabolic disorders. Cystinuria was observed in 6 and xanthinuria in 3 cases. The main constituents of calculi analyses in the upper urinary tract were calcium oxalate followed by ammonium acid urate. In the lower urinary tract ammonium acid urate and oxalate were seen with equal frequency, followed by uric acid. 16 children had staghorn calculi with an age profile of 5-13 years. Predominant symptoms were flank pain and gross hematuria. In 4 cases the calculi were bilateral. The calculi were removed successfully by pyelotomy and extensive pyelolithotomy. In 2 cases with more branched-out staghorn calculi and separate fragments, a logitudinal extensive nephrotomy was performed. In the absence of recurrent stones, renal growth and function were satisfactory postoperatively. In the majority of the cases the analyses of the staghorn calculi revealed phosphate.

We have studied retrospectively 68 children who presented with urolithiasis between 1965 and 1986. Male to female ratio was 1.83 to 1 and the mean age was 9.5 years. Fifty four children (79%) had calculi in the upper urinary tract, 9 (13%) had in the lower, and 4 (6%) had calculi both in the upper and lower urinary tract. The most common presenting symptoms were gross hematuria (53%) and abdominal or flank pain (38%). Predisposing factors could be found only in 21 children (31%). Twenty four of the 68 patients (35%) had open surgery and 16 patients (24%) passed their stones spontaneously. Twenty one stones were analyzed by infrared spectroscopy. Infectious stone was more frequent than in adult cases. Among children five years old and younger, infectious stone was the most frequent. Among children over five years old, the number of idiopathic calcium stone has been on the increase with the years.

Periodic structures with equally spaced radial striations, identified as Liesegang-like rings, were encountered in fine needle aspirates of two patients' hemorrhagic renal/perirenal cysts. The patients, one 60 and the other 39 years old, had acute right-flank pain; both underwent nephrectomy. The ring structures ranged in size from 8 microns to 200 microns in diameter and had regularly striated double walls. Histochemical and immunoperoxidase tests for iron, calcium, mucopolysaccharides, amyloid, keratin and hemoglobin performed on the tissue sections of the resected specimens gave negative results. With electron microscopy, the ring structures of one of the cases displayed a fine fibrillary composition. Since these Liesegang-like structures may be mistaken for parasites or necrotic tissue, pathologists should be aware of them. To our knowledge, this is the first report of Liesegang-like rings in the cytology literature.

We report a case of 2, 8-dihydroxyadenine (2, 8-DHA) urolithiasis. A 39-year-old female was referred to our hospital with the complaint of right flank pain. An X-ray examination showed right hydronephrosis. On May 1986, right percutaneous nephrolithotripsy was performed. Infrared spectroanalysis revealed 2, 8-DHA and calcium phosphate mixed calculus. The adenine phosphoribosyltransferase activity in erythrocytes was partially deficient. Since the operation, 300 mg/day of allopurinol has been administered, and there have been no signs of recurrence.

The loin pain hematuria syndrome has been characterized as a constellation of severe recurrent flank pain and hematuria, occurring predominantly in young women. We studied a 17-year-old woman who had recurrent right flank pain, gross hematuria, and fever, without evidence of urinary tract infection. Her physical exam was remarkable for right costovertebral angle tenderness and a normal BP. Her urinalysis showed blood and protein but her creatinine clearance and 24-hour urinary calcium excretion were normal. A kidney biopsy was remarkable for arteriolar subintimal fibrous thickening and fibrin deposition, but no glomerulonephritis. Her peripheral hemostasis evaluation was normal except for circulating platelet aggregates and elevated fibrinopeptide A levels. On two occasions, her serum was unable to normally support prostacyclin (PGI2) production by cultured human umbilical endothelial cells, as measured by radioimmunoassay (RIA) of its stable metabolite 6-keto-PGF alpha. Blood samples from the right renal vein and inferior vena cava revealed a selective elevation of fibrinopeptide A in the right renal venous effluent. The presence of circulating platelet aggregates and elevated levels of fibrinopeptide A (a cleavage product of fibrin) suggests that platelet activation and fibrin deposition may play a role in the pathogenesis of this disorder. The inability of her serum to normally support the production of the potent antiplatelet and antithrombotic substance, PGI2, could represent a primary renovascular endothelial cell defect.

Crossed renal ectopia is a relatively rare renal anomaly. A 49-year-old man with macrohematuria and right flank pain was admitted to our hospital. Various urological examinations were carried out, and a diagnosis of left crossed renal ectopia with renal stone was made. Pyelolithotomy was performed and stone analysis revealed a calcium oxalate. In Japan, 166 cases of crossed renal ectopia have been reported and 15 of them including our case were associated with urinary tract stones.

Idiopathic hypercalciuria (IH) in adults is recognized as a cause of urolithiasis. If IH is symptomatic, the symptoms are hematuria, renal colic, or obstructive uropathy with or without infection. In children, IH has been linked to the spectrum of urinary symptoms including hematuria, pyuria, dysuria, recurrent urinary infections, abdominal or suprapubic pain, proteinuria, and the frequency-urgency syndrome. Hematuria may appear prior to the appearance of stones, and thiazide therapy appears to prevent stone formation by decreasing urinary calcium excretion. This report describes an older adolescent with hematuria and flank pain. His urinary chemistry values were not consistently typical of IH, but a thiazide trial with withdrawal challenge was diagnostic. His case is remarkable because, though essentially an adult, his disease was typical of prepubertal disease. Adolescents with unexplained urinary symptoms should be evaluated for IH. The urinary calcium-creatinine ratio may not be elevated, and timed urinary calcium may be equivocal. In some cases a thiazide trial may be valuable and cost effective.

Periodic structures with equally spaced radial striations identified as Liesegang-like rings were seen in two male patients' hemorrhagic perirenal cysts. The patients, one 48 and the other 60 years old, had acute right-flank pain and anemia; both had nephrectomy. The rings, initially believed to represent parasites (Dioctophyma renale), were from 8 to 500 micron in diameter and had uniform, pink-tan, radially striated double walls. Multiple small rings within a larger ring predominated in one case. Morphologically, the rings differed from D. renale when compared with specimens from animals infected naturally or experimentally with the giant kidney worm. Histochemical and immunoperoxidase tests for iron, calcium, mucopolysaccharides, amyloid, keratin, and hemoglobin had negative results. Energy-dispersive x-ray elemental analysis demonstrated no detectable elements; ultrastructurally, however, the rings displayed a fine fibrillary composition with a concentric and radial pattern. These rings are believed to be an end product of a phenomenon resembling or are, in fact, the Liesegang phenomenon. Because these Liesegang-like structures may be mistaken for parasites on fine-needle aspiration or surgical specimens of hemorrhagic areas, pathologists should be aware of them.

A case of milk of calcium renal stone is reported. The patient was a 24-year-old woman who complained of dull flank pain on the right side. A plain film of the abdomen revealed a right renal stone, which showed peculiar radiopacity of a half-moon shape in the upright position. The operation was performed on July 6, 1984. Postoperative chemical analysis of sand granules showed calcium oxalate and calcium phosphate.
