The diagnostic work-up of the urologic patient must be tailored to the presenting symptom complex, carefully selecting from the many modilities available, those most likely to establish the diagnosis and extent of the suspected lesions. Intravenous urography is the most rewarding initial procedure for many presenting symptoms, including suspected masses, pyuria, hematuria, and flank pain. Nuclear imaging is particularly effective in differentiating renal lobulations from true masses, in demonstrating parenchymal scarring in chronic pyelonephritis when the IVP is equivocal, and in assessing the decrease in perfusion and function in obstructive nephropathy when the IVP is indeterminate. It is the preferred procedure for acute renal infarction and acute tubular necrosis and has a greater sensitivity of detection for renal trauma than the IVP. Gallium-67 renal imaging appear helpful in the detection of occult pyelonephritis or interstitial nephritis. However, it cannot differentiate focal acute pyelonephritis from abscess or abscess from neoplasm. Ultrasoneography is the initial procedure of choice in the differentiation of cystic from solid renal masses and in anuria or oliguria. When a kidney fails to visualize by IVP or nuclear imaging, it can confirm or rule out obstruction. In upper tract infections, it may demonstrate renal or perirenal abscess. Although retrograde pyelography is performed less frequently in recent years, it remains extremely useful in confirming and relieving obstructive uropathy and in delineating tumors of the collecting system. Computed tomography effectively demonstrates hydronephrosis, renal abscess, tumors, and cysts and retroperitoneal involvement. More experience is needed to judge the efficiency of "dynamic" CT for the quantification of renal function. Renal angiography remains invaluable as a secondary procedure (as opposed to initial screening) in renal trauma, vascular anomalies, and in renal tumors to delineate the anatomy of the arterial supply and possible renal vein involvement.

Autosomal dominant polycystic kidney disease is one of the most commonly inherited diseases in the United States. It affects nearly 500,000 Americans and accounts for 5 to 10 percent of patients with end-stage renal disease. Diagnosis is usually made in middle age, when complications such as hypertension, pain and hematuria develop. Renal complications include hypertension, cyst infection and hemorrhage, hematuria and flank pain. Other manifestations and related conditions include polycystic liver disease, cerebral aneurysm, cardiac valve abnormalities and diverticulosis. The severity and course of the disease vary in individual patients. Management involves the control of hypertension and treatment of complications. Genetic counseling is important. Dialysis and renal transplantation often are successful treatments in patients who develop renal failure.

Cisplatin is a potent tubular toxin with a high incidence of nephrotoxicity. Carboplatin is considered less nephrotoxic but can still cause tubular injury and interstitial nephritis in patients who have been previously treated with cisplatin. The affected individuals usually have nonoliguric renal failure with a urine output of more than a liter per day. We present a 57-year-old white woman with no history of renal disease who underwent a total abdominal hysterectomy and bilateral salpingo-oophorectomy for stage IC ovarian carcinoma. One month later, she received chemotherapy with paclitaxel (Taxol) and carboplatin. On the following day, she developed frank hematuria and flank pain associated with a diminished urine output. Intravenous pyelogram (IVP) showed bilateral hydronephrosis with a total blockage of dye flow at the level of intraureteral lucencies consistent with bilateral blood clots. Her coagulation profile and uric acid was normal. Her acute renal failure (ARF) spontaneously resolved in the following 24 hours, with a brisk diuresis presumably due to clot lysis. The follow-up IVP showed a resolution of obstructive changes. A review of the literature shows a previous case in which high doses of carboplatin were implicated as the cause of hemorrhagic cystitis, presumably by toxicity to transitional epithelium of the bladder. We believe that the current case represents carboplatin-induced damage to the transitional epithelium in the renal pelvi and ureters causing gross hematuria and blood clots, resulting in bilateral ureteral obstruction and hydronephrosis.

Autosomal dominant polycystic kidney disease (ADPKD) is often characterized by end-stage renal disease (ESRD) and problems including pain, hematuria, and infection. Open nephrectomy is curative; however, the morbidity of the procedure is considerable. Between 1995 and 1998, 11 laparoscopic nephrectomies were performed on nine symptomatic patients (five men and four women) with ESRD and ADPKD. Two patients underwent a staged bilateral laparoscopic nephrectomy. All patients presented with abdominal or flank pain and an abdominal mass. Other clinical problems included hypertension in eight patients, urinary tract infections in two patients, and gross hematuria in one patient. Seven patients were receiving long-term dialysis treatment, and two patients had undergone prior renal transplantation. Patients were evaluated for preoperative and postoperative pain, analgesic use, hospital course, and convalescence. The overall average operative time was 6.3 hours, with an average estimated blood loss of 153 mL. Eight nephrectomy specimens were removed by morcellation, and three specimens were removed intact through a 7- to 12-cm incision. The average hospital stay was 3 days, and the average time to normal activity was 5 weeks. With a mean follow-up of 31 months, all nine patients reported elimination of their preoperative pain based on a pain analogue score. Six major and two minor complications occurred, including blood transfusion, a vena cavotomy, splenic cyanosis, pulmonary embolism, clotted arteriovenous fistula, and brachial plexus injury. Incisional hernias occurred in two of the three patients who underwent open removal. One patient noted improvement, and two patients noted resolution of their hypertension postoperatively. Laparoscopic nephrectomy in patients with ADPKD and ESRD offers an effective alternative to open nephrectomy to manage renal-related pain. This procedure provides the benefits of minimal intraoperative blood loss, minimal postoperative pain, brief hospital stay, and rapid convalescence.

Acquired cystic disease of the kidney (ACDK) is a common phenomenon in long-term adult dialysis patients with end-stage renal disease. Renal hemorrhage and neoplastic transformation of the cyst are two major complications of this entity and these two can occur independently. Here we describe a 65-year-old man with a history of hemodialysis-dependent end-stage renal failure for 12 years presented with macroscopic hematuria and right flank pain. Investigations revealed right massive perirenal and subcapsular hematoma with ACDK. The hemorrhagic state required nephrectomy of the right kidney. Histological study showed ACDK with massive subcapsular and perinephric hematoma containing minimal clear cell carcinoma region(0.5 cm in diameter). Although a causal relationship between renal hemorrhage and renal cell carcinoma in this patient was unproven, the present case suggests radical surgery can be a recommendable treatment modality of hemorrhagic ACDK.

Acquired cystic kidney disease (ACKD) is a complication of end-stage renal disease, the prevalence of which is related to dialysis duration; incidence of ACKD and associated conditions (neoplasia, hemorrhage) have decreased with improvements in renal transplantation and with the ageing of the dialysis population. This report regards spontaneous kidney rupture in a 57-year old patient, on home hemodialysis for 11 years, with ACKD for 5 years. At the end of a dialysis session, the patient reported sudden onset of colicky flank pain, followed by macrohematuria. Pain remitted with low doses of pain relievers, leaving dull flank discomfort. The patient self diagnosed a renal colic, and called the hospital two days later. At referral, two large hemorrhagic renal masses (7 and 2.8 cm) were found at ultrasound and CT scan. At surgery, kidney rupture was diagnosed. This case highlights the life threatening complications associated with ACKD, and underlines that massive renal hemorrhage may occur with relatively minor symptoms.

A 28-year-old female presented for evaluation of left flank pain and polyuria after having been exposed to cadmium in the jewelry manufacturing industry for approximately 3 years. This patient possessed both elevated 24-hr urinary ss2-microglobulin and elevated blood cadmium levels. Approximately 6 months after initial presentation, the patient resigned from her job due to shortness of breath, chest pain, and anxiety. Exposure to cadmium in the jewelry industry is a significant source of occupational cadmium exposure. Other occupational sources include the manufacture of nickel-cadmium batteries, metal plating, zinc and lead refining, smelting of cadmium and lead, and production of plastics. Cadmium is also an environmental pollutant that accumulates in leafy vegetables and plants, including tobacco. Major toxicities anticipated from cadmium exposure involve the renal, pulmonary, and, to a lesser extent, gastrointestinal systems. These include the development of renal proximal tubular dysfunction, glomerular damage with progressive renal disease, and respiratory symptoms including pneumonitis and emphysema. Low-level cadmium exposure has also been associated with increased urinary calcium excretion and direct bone toxicity, effects that recent research suggests may result in the development of osteoporosis. The body burden of cadmium, over half of which may reside in the kidneys, is most often measured through the use of urinary cadmium levels. Blood cadmium measurements generally reflect current or recent exposure and are especially useful in cases with a short exposure period and only minimal accumulation of cadmium in the kidneys. Both ss2-microglobulin and alpha1-microglobulin serve as organ-specific, early-effect biomarkers of tubular proteinuria and thus play a role in identifying early signs of cadmium-induced renal damage in those with potential exposures. In addition to ensuring workplace compliance with Occupational Safety and Health Administration-mandated monitoring and screening measures, it is prudent for those with cadmium exposure to maintain adequate intake of both iron and calcium, appropriate measures even in the absence of exposure.

Seven patients aged 13 to 17.5 years developed acute renal failure after treatment with a variety of non-steroidal anti-inflammatory drugs (NSAID): naproxen, diclofenac, ibuprofen, dipyrone and paracetamol. Six of the patients used more than one kind of NSAID. None of the patients had previous history of renal disease or concomitant treatment with other drugs. The time interval between NSAID administration to the emergence of symptoms ranged from 1 to 4 days. The most common presenting symptoms were flank pain (4 patients), abdominal pain (3 patients) and vomiting (3 patients). All patients had normal urine output. Microscopic hematuria and proteinuria were found in 5 patients and leukocyturia in 2. Serum creatinine ranged from 1.3 to 8.3 mg% at presentation. Kidney biopsy was performed in 3 patients and showed findings consistent with mild interstitial inflammation in 1 patient, and normal renal tissue in 2. All patients were treated with intravenous fluids, 1 received corticosteroids. Renal function completely normalized in all patients within 7 to 16 days.

Polycystic kidney disease, an inherited systemic disorder, is characterized by the development of multiple cysts in the kidneys and other organs. Patients can present at any age, but more often come to clinical attention (unless there is a family history) after age 30. Patients who are diagnosed before age 30 have a worse renal survival. Although palpation of the abdomen occasionally provides a clue to the presence of polycystic kidney disease, radiographic procedures most often suggest the diagnosis. Mutations in the PKD1 or PKD2 genes give rise to cyst formation. Flank pain, hematuria, polyuria, nephrolithiasis, urinary tract infections, and hypertension may be part of the syndrome of polycystic kidney disease. It is the fourth most common cause of end-stage renal disease. Blood pressure treatment goals are less than 130/80 mm Hg. Treatment should include the use of angiotensin-converting enzyme inhibitors.

In three women on chronic haemodialysis because of end-stage renal disease who were 40, 59, and 73 years of age respectively, spontaneous renal bleeding was diagnosed. The first two patients presented with acute flank pain and signs of sudden blood loss, the third one had chronic abdominal pain and anaemia. A CT scan demonstrated perirenal bleeding in all three patients and expansion into the retroperitoneal space in the first and third patient. In the latter two patients, acquired renal cysts had been visible during earlier abdominal ultrasound. None of the patients had severe hypertension, but all of them had received medication enhancing bleeding tendency, such as nadroparin, which was administered during haemodialysis. The first and the last patient were treated conservatively and survived. The second patient was haemodynamically unstable and underwent embolisation to stop the bleeding. She died in hospital after fifteen days due to the complications of a cardiac arrest. Abdominal CT or ultrasound is the technique of choice to evaluate patients with end-stage renal disease with loin pain or bleeding. Most of the time, conservative treatment suffices.
