Three patients who underwent live donor renal transplantation subsequently developed calculi in their allografts. Hypercalcaemia and secondary hyperparathyroidism were present in 2 cases and these were treated by subtotal parathyroidectomy. Urinary stagnation and infection were contributory factors in the third case and reimplantation of the ureter was necessary. In all patients no further calculi have developed following treatment and allograft function remains satisfactory.

Of 37 adult patients with ureteroceles, 13 also had calculous disease (35 per cent). Of these 13 cases 7 had single ureters and 6 had duplicated ones. None had a metabolic or urinary abnormality such as hypercalcemia, gout, hypercalciuria or hyperuricuria. Two of the patients were a mother and daugher--the first reported familial incidence of ureterocele with calculous disease. A surgical technique is described for removal of the calculus, excision of the ureterocele and reimplantation of the ureter. The procedure was used in 4 of the 7 patients with single ureters, while the stone passed spontaneously in 2 patients and was treated by ureterolithotomy in 1. A modification of the technique was used in 2 of the 6 patients with duplicated ureters but other surgical procedures were used in the remaining 4. Of 10 stones that were analyzed 2 were struvite and none contained cystine or uric acid. Long-term followup is a requisite to assure control of this clinical entity.

A 19-month-old entire male French lop rabbit was presented with a two-week history of a depressed appetite and lethargy. Clinical and laboratory findings, together with abdominal radiographic studies, suggested a diagnosis of right-sided calcium ureterolithiasis. Management included the surgical removal and analysis of the urolith. Confirmation of a calcium-containing urolith and the presence of hypercalcaemia necessitated the introduction of a low calcium diet. Recovery was complicated by the occurrence of a second urolith within the left ureter. This was also removed successfully by surgical means. The rabbit made a full recovery and assessment of serial serum calcium concentration has since confirmed the long-term maintenance of calcium levels within their normal range.

We report two cases of squamous cell carcinoma of upper urinary tract with hypercalcemia. Case 1; a 54 year old female with primary squamous cell carcinoma (SCC) of right ureter showed marked hypercalcemia and leukocytosis. High levels of serum parathyroid hormone-related peptide (PTHrP) and granulocyte colony stimulating factor (G-CSF) were detected. Although chemotherapy of cisplatin and 5-fluorouracil with radiotherapy was effective, thereafter recurrence was occurred in renal pelvis, and the patient died 17 months after the initiation of therapy. Case 2; a 54 year old male of primary SCC of right renal pelvis with local lymphadenopathy and anterior mediastinal metastases showed marked hypercalcemia. High levels of PTHrP were detected. Although the patient was administered UFT with palliative radiotherapy to the anterior mediastinum, he died 2 months after the initiation of therapy. To our knowledge, the case 1 is the third case that of the high levels of serum PTHrP and G-CSF simultaneously in squamous cell carcinoma of upper urinary tract.

An ultrasonographic reproductive health examination of a 26-yr-old female African elephant (Loxodonta africana) revealed bilateral ureteral wall thickening and dilatation. On ultrasonographic examination, the bladder and both ureters were normal near the trigone; however, the cranial-most aspect of each ureter was dilated and thickened for a length of 30-50 cm. The same month, elevated blood creatinine (3.0 mg/dl), and urine protein-creatinine ratio (4.0) were observed. Chronic renal failure was diagnosed based on these abnormalities, and the persistent ureteral dilatation was seen on subsequent ultrasound examinations. Complete blood cell counts, serum chemistries, and urinalyses remained relatively unchanged until 24 mo after diagnosis, at which time azotemia, hypophosphatemia, and hypercalcemia (including elevated ionized calcium) developed. Hydronephrosis of both kidneys and prominent sacculation of the left ureter were noted on ultrasonographic examination. Lethargy, ventral edema, and oral mucosal ulceration acutely developed 30 mo after diagnosis. Although blood urea nitrogen remained elevated, creatinine, total calcium, and ionized calcium returned to within reference ranges at that time. Due to rapid clinical decline and grave prognosis, humane euthanasia was elected. Bilateral ureteral dilatation, dysplasia of the right kidney, and chronic nephritis of the left kidney were identified postmortem.

A previously well woman, 44 years of age, presented with 3 years of recurrent bilateral renal colic. Despite an increase in fluid intake and a low calcium diet, the intermittent episodes of renal colic continued and had become more frequent in the last year. An abdominal X-ray was performed, which showed some radio-opaque areas on both renal silhouettes (see Figure 1). Two stones in the right pelvic ureter were also seen following administration of contrast. No obstruction of the urinary tract was evident. Urinalysis revealed leukocyturia, a pH of 6.5 and specific gravity of 1.015. Blood testing showed hypercalcaemia of 2.96 mmol/L and hypophosphataemia of 0.71 mmol/L.

A 10-yr-old boy visited Minoh City Hospital complaining of gross hematuria. Laboratory investigations revealed hypercalcemia, hypophosphatemia, and elevated serum levels of parathyroid hormone. A stone was found in the right ureter with drip infusion pyelography. A parathyroid adenoma was successfully diagnosed with computed tomography, ultrasonography, and methoxy-2-isobutyl isonitrile (MIBI) scintigraphy. Multiple endocrine neoplasia was ruled out by normal results of endocrine laboratory examinations. Extracorporeal shock wave lithotripsy was performed to treat the urolithiasis, and the parathyroid adenoma was surgically removed. Primary hyperparathyroidism is rare in childhood; however, this case suggests that gross hematuria is an important sign of hyperparathyroidism.
