We investigated the clinical significance of the serum S100ao protein in patients with urogenital diseases. The serum levels of S100ao protein were measured in 179 patients with urogenital diseases and 180 healthy volunteers. The mean value of S100ao protein in serum from healthy volunteers was 203 +/- 107 pg/ml (Mean +/- SD). Therefore, the cut-off level was set to 524 pg/ml (Mean +/- 3SD). The levels of S100ao protein in serum were significantly higher in men than in women (P less than 0.05). The levels of S100ao protein in serum were significantly high in the patients in their fifties and sixties compared with the other patients (P less than 0.01). When serum levels exceeding the cut-off level were considered to be positive, the percentages of positivity in each disease were as follows: renal cell carcinoma; 38.7%, bladder tumor; 9.1%, prostatic carcinoma; 12.5%, testicular tumor; 0%, benign prostatic hypertrophy; 7.4%, urolithiasis; 7.1% and chronic renal failure; 100%. The levels of S100ao protein in serum were significantly correlated with those of BUN, serum creatinine and endogenous creatinine clearance, respectively. S100ao protein in serum was increased immediately after operation and returned to the normal range within one to two weeks after operation. As described above, the level of S100ao protein in serum was affected by renal function, operative procedures and age. However, the positive rate of S100ao protein was so high in patients with renal cell carcinoma that serum S100ao protein might be a valuable tumor marker in those patients.

The purpose of this study was to determine the incidence of the urological diseases of the kidney. Among 4,094 persons (3,146 men and 948 women) studied, 86 cases of renal cyst, 7 cases of urolithiasis, 3 cases of cystic kidney, and one case of renal cell carcinoma were discovered. The rate of renal cyst was two times higher in men than in women. One sixth of renal cyst patients showed microscopic hematuria. Renal cysts tended to progress in number and size with age. The size of the renal cyst did not correlate with the appearance rate of microscopic hematuria.

On 138 patients with radiologic filling defects in the ureter and renal pelvis lavage cytology was done. With this method it was possible to recognize clearly 39 of 47 urothelial tumors of renal pelvis and ureter (81,3%). Lavage cytology failed in patients with hypernephroma. Severe cellular atypias could be seen in patients with urolithiasis and inflammation. The diagnostic reliability of lavage cytology with urothelial tumors of renal pelvis and ureter is far greater than that of exfoliative urinary cytology and reaches results as good as those from brush biopsy.

Renal carcinoma and urolithiasis combine rather rarely. Postnephrectomy patients often consult the urologist when the condition is serious because of complications resultant from uroliths in the contralateral kedney. In view of solitary kidney, progressive chronic pyelonephritis, associated chronic renal failure surgical treatment of the condition becomes risky and necessitates individual approach to choice of therapeutic policy and definition of indications to urolithiasis treatment in patients after nephrectomy for renal carcinoma. This includes the decision whether to perform nephrolithiasis before or after nephrectomy and whether to attempt any surgery in the absence of urolithiasis clinical symptoms.

In vivo and in vitro experiments were made to study percutaneous intrarenal ultrasonography (PIU). The transurethral ultrasonic probe (5.5 MHz, 1850 "Bruel&Kjer, Denmark) was inserted through the nephrostomic fistula in the dilated pelvis with the tubus of the nephroscope K. Storz 27093B. Scanning of the cavitary renal system and ureteropelvic zone was conducted by moving the probe in the longitudinal and transverse directions. The experiment on 21 removed kidneys investigated potentialities of PIU in hydronephrotic transformation caused by ureteropelvic stricture (4 kidneys), urolithiasis (7 kidneys), carcinoma of renal parenchyma (5 kidneys), pelvic cancer (1 kidney), combined renal cell and epithelial renal carcinoma (1 kidney); in pyonephrosis (1 kidney) and contracted kidney (2 kidneys). 43 patients (19 males and 24 females aged 7 to 63 years) have undergone PIU in the course of percutaneous nephrolithotripsy (n = 23), percutaneous endopyelotomy (n = 15) and percutaneous endoresection of solitary renal cyst (n = 5). PIU accurately localizes residual and x-ray-negative concrement fragments raising the effectiveness of percutaneous nephrolithotripsy, precisely differentiates internal renal structures, visualizes pelvic wall, vessels and tissues of the renal sinus, provides additional information about ureteropelvic zone and its changes. PIU can find wide application in intraoperative diagnosis of different renal and upper urinary tract diseases.

Urolithiasis and calcium oxalate crystal deposition diseases are still significant medical problems. In the course of nephrocalcin cDNA cloning, we have identified FKBP-12 as an inhibitory molecule of calcium oxalate crystal growth. lambdagt 11 cDNA libraries were constructed from renal carcinoma tissues and screened for nephrocalcin cDNA clones using anti-nephrocalcin antibody as a probe. Clones expressing recombinant proteins, which appeared to be antigenically cross-reactive to nephrocalcin, were isolated and their DNA sequences and inhibitory activities on the calcium oxalate crystal growth were determined. One of the clone lambda gt 11 #31-1 had a partial fragment (80 bp) of FKBP-12 cDNA as an insert. Therefore, a full-length FKBP-12 cDNA was PCR-cloned from the lambda gt 11 renal carcinoma cDNA library and was subcloned into an expression vector. The resultant recombinant FKBP-12 exhibited an inhibitory activity on the calcium oxalate crystal growth (Kd=10(-7) M). Physiological effect of the extracellular FKBP-12 was investigated in terms of macrophage activation and proinflammatory cytokine gene induction. Extracellular FKBP-12 failed to activate macrophages even at high concentrations. FKBP-12 seems an anti-stone molecule for the oxalate crystal deposition disease and recurrent stone diseases.

A 72-year-old non-diabetic uremic woman underwent right nephrectomy for urolithiasis at the age of 50. Because pyuria, fever, chilliness and left flank pain developed during preparing for arteriovenous fistula, she was admitted to National Cheng Kung University Hospital. Renal cell carcinoma (RCC) complicated with emphysematous pyelonephritis (EPN) was diagnosed and immediately treated with antibiotics and CT-guided percutaneous catheter drainage. Cultures of pus and blood yielded Escherichia coli. She received left radical nephrectomy later for the control of persistent sepsis and removal of left renal tumor. The pathology of the tumor was composed of a glandular arrangement of granular cells with the occasional atypism, and renal parenchyma had been totally replaced by RCC. The non-tumor part of the kidney showed chronic pyelonephritis. Five months later, multiple metastases developed. We reported this first uremic case with EPN and RCC, but without diabetes mellitus and urinary tract obstruction. The gas formation may be due to large RCC, which caused impaired tissue perfusion and E. coli infection.

Crossed renal ectopia its a rare congenital malformation and in most cases it presents with fusion of both kidneys. Patients should be asynptomatic until 4a-5a decade and at that time they unfold urinary infection, urolithiasis, abdominal mass or pain that simulates a gastric disease. We report a case of renal cell carcinoma in a patient with crossed fused renal ectopia, showed in a Scan that was performed for gastric disease suspicion.

Overweightness and obesity are associated with many hemodynamic, structural, and histopathologic alterations in the kidney and with metabolic and biochemical changes that predispose to these abnormalities. Consequent to these disorders, these individuals are more likely to develop chronic kidney disease and end-stage renal failure. Overweight and obese people are more prone to develop albuminuria and, for at least some types of kidney disease, a greater amount of albuminuria and more rapid progression of renal failure. These individuals are more likely to develop diabetes mellitus and hypertension. Diabetic nephropathy, hypertensive nephrosclerosis, focal and segmental glomerulosclerosis, renal cell carcinoma, and urate and calcium oxalate urolithiasis are the more common kidney and urological diseases reported in obese people. Preliminary data indicate that many of the clinical and nephropathologic manifestations associated with obesity can be reversed or ameliorated with reductions in body fat induced by dietary energy restriction or surgical procedures that reduce intake and gastrointestinal absorption of calories.
