90 case records of renal cysts in adults submitted to surgery are studied. A simple pathological classification is proposed. The accompanying signs were, hematuria in 30 p. 100 of cases, but one should always seek another cause; renal colic is present in 22 p. 100 of cases, a palpable tumour in 50 p. 100, on the other hand, infection of the cyst is rare. 35 p. 100 of the cysts were associated with another disease, usually obstructive uropathy, and there were 3 cases of association with carcinoma of the kidney in this series. Pre-operative diagnosis, eliminating carcinoma of the kidney, was ensured by intravenous urography and echotomography which permitted us to restrict the indications for arteriography and aspiration of the cyst. Surgical treatment permits resection of the salient dome of the cyst in the absence of general contra-indications, in order to suppress symptoms due to the cyst and above all, eliminate carcinoma of the kidney. The post-operative period was uneventful and the mortality nil.

A prospective study was undertaken to determine the incidence of spontaneous extravasation of contrast in 82 patients with acute renal colic. The extravasation rate among 37 patients receiving 75 ml of contrast was 8.1%, while the rate among 45 patients receiving either 300 ml of 30% solution by infusion or a 140 ml bolus dose was 24.4%; overall the rate was 17%. Thus the incidence of extravasation was shown to increase with higher doses of contrast media. The primary dose in acute renal colic or other forms of obstructive uropathy should be in the low range (20-25 g 1-); reinjection after screening can be undertaken if necessary.

To assess whether ultrasonography (US) with or without plain abdominal radiography (kidney, ureter, bladder [KUB] radiography) can replace intravenous urography (IVU) in detection of acute urinary tract obstruction, 101 consecutive patients with renal colic were evaluated with US followed immediately by IVU. Receiver operating characteristic (ROC) curves for US diagnosis of acute urinary tract obstruction yielded sensitivities of 91% and 92% for two reviewers at a specificity of 90%. There was no statistically significant difference between US and IVU results. When US was combined with KUB radiography, ROC curves yielded sensitivities of 94% and 97% for two reviewers at a specificity of 90%.KUB radiography alone was of limited diagnostic value. For US alone, no false-positive results occurred, and the false-negative results (n = 9 and n = 6 for two reviewers) were encountered in cases of grade 1 hydronephrosis and nondilated obstructive uropathy. The authors conclude that US combined with KUB radiography can replace IVU in initial evaluation and follow-up of the great majority of patients with renal colic.

Renal papillary necrosis in 4 diabetic patients is described. Two of them had underlying diabetic nephropathy. Urinary tract infection was present in all of them. Three patients had passed fleshy material in the urine while in one the diagnosis was established by excretory urography. Two patients required haemodialysis for acute renal failure caused by sloughed papillae. The condition should be suspected in diabetic subjects who develop recurrent episodes of urinary tract infection, renal colic, haematuria or obstructive uropathy.

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.

The Storz Modulith SL20 is a third-generation lithotripter which was installed in our hospital in March 1991. The aim of this paper is to evaluate our results in the management of renal calculi using this machine. We report our experience in the treatment of the first 215 renal units (118 renal and 83 ureteric) in 190 patients with a minimum follow-up period of three months. Success for renal stones was defined as stone-free or with insignificant residual fragments of less than 4 mm in size post therapy. Success for ureteric stones was defined as stone-free after therapy. The success rate for renal calculi was 88% and for ureteric calculi 71%. The mean number of sessions to achieve these results for renal calculi was 1.6 and for ureteric calculi 1.4. Of the failures, only 1.9% required open surgery whilst the remainder were dealt with using minimally invasive procedures like intracorporeal laser lithotripsy. There was no mortality in our series. Complications occurred in four patients, who required hospitalisation for renal colic (n = 1), urinary tract infection (n = 1) and obstructive uropathy (n = 2).

Analgesic nephropathy is a unique drug-induced kidney disease characterized pathologically by renal papillary necrosis and chronic interstitial nephritis, and is the result of excessive consumption of combination antipyretic analgesics. The clinical features of the disorder relate mainly to the papillary necrosis, renal colic, and obstructive uropathy and the development of chronic renal failure in a small percentage of patients. There are significant geographic variations in the clinical features that may be related to the differing combinations of analgesics. The pathogenesis of the disease is in part related to the kidneys' ability to concentrate drugs in the papillae. The following sequence of events presents a plausible explanation for the evolution of the disease. If a combination of phenacetin and aspirin is ingested, the following steps occur. Phenacetin is converted in the gut and liver to acetaminophen by first-pass metabolism. Acetaminophen is then taken up by the kidney and excreted. During its excretion, acetaminophen becomes concentrated in the papillae of the kidney during physiologic degrees of antidiuresis, the concentration being up to five times the intracellular concentration of other tissues. Acetaminophen undergoes oxidative metabolism by prostaglandin H synthase to a reactive quinoneimine that is conjugated to glutathione. If acetaminophen is present alone, there is sufficient glutathione generated in the papillae to detoxify the reactive intermediate. If the acetaminophen is ingested with aspirin, the aspirin is converted to salicylate and salicylate becomes highly concentrated in both the cortex and papillae of the kidney. Salicylate is a potent depletor of glutathione. The mechanism is not completely understood; however, the inhibition of the production of NADPH via the pentose shunt is a possible explanation. With the cellular glutathione depleted, the reactive metabolite of acetaminophen then produces lipid peroxides and arylation of tissue proteins, ultimately resulting in necrosis of the papillae.

Acute flank pain is commonly encountered in the emergency department, and often requires imaging to establish its cause. For decades intravenous urography and sonography have been the primary media for evaluating flank pain. Recently, noncontrast spiral CT (NCSCT) has been shown to be accurate and highly successful in diagnosing cause in such cases. We evaluated its use in the diagnosis of acute flank pain. During a 7-month period, 147 such cases had NCSCT imaging immediately after initial evaluation in the emergency department. Using a spiral CT scan without oral or i.v. contrast media, 109 of 147 cases were found to have ureteral stones, and 34 others to have other urological conditions unrelated to the cause of pain; 38 CT scans were negative for ureterolithiasis and in 14 non-urological disease was diagnosed. NCSCT is a valuable diagnostic technique for patients in the emergency department with flank pain. It rapidly and accurately detects ureteral stones causing renal colic and also detects extra-urinary causes of acute flank pain.

Nephrolithiasis is an infrequent complication following renal transplantation and acquisition of a stone with the donor kidney is rare. Indeed only a few cases of donor stones causing renal failure have been reported. Since the grafted kidney is denervated, stone disease may not present with the classic renal colic but rather with acute renal failure secondary to the obstruction. Identification of the precise cause is critical in order to avoid inappropriate therapy. We present our experience of two renal transplant patients who developed obstructive uropathy by stones originating from the donor kidneys.

A 31 year old man with prosthetic aortic valve replacement presented with sudden onset of colic right flank pain. Analysis of the urine revealed haematuria, and the international normalised ratio was suboptimal. The patient was misdiagnosed as having ureteral colic. On the second day, an ultrasound showed no signs of obstructive uropathy, and there was no evidence of absent function on intravenous pyelogram. Computed tomography with contrast agent was performed and revealed a right renal infarction. Renal angiography demonstrated total occlusion of the right renal artery. Fibrinolytic therapy and angioplasty were unsuccessful. To our knowledge, aortic prosthetic valve thrombus as a source of renal artery embolism mimicking renal colic has not been reported previously. This case underlines the importance of renal colic as a manifestation of renal infarction in patients with prosthetic valves and the need for a high index of suspicion of renal embolism.
