Renal calculi are an infrequent but significant management problem during pregnancy. We reviewed all cases of renal colic occurring during pregnancy between 1979 and 1990 at Grace Hospital, a tertiary care obstetrical hospital in Vancouver, British Columbia. Of the patients 80 had a discharge diagnosis of renal colic and pregnancy during this 11-year period. Calculi were confirmed in 57 patients. Of the patients 66% were multiparous and 99% of the calculi occurred during either the second or third trimester. The most common symptom was flank pain seen in 89% of the patients, while greater than 95% displayed either microscopic or gross hematuria. Methods of radiographic diagnosis included ultrasonography and limited stage excretory urography. A total of 84% of patients passed stones spontaneously. Indications for urological or obstetrical intervention included persistent pain, sepsis, progressive hydronephrosis, solitary kidney or high grade obstruction. There were 37 procedures done in 23 patients. The most common procedure was placement of a ureteral stent. The complication rate associated with intrapartum intervention and stent passage in the 23 patients was 16%. All patients with a ureteral stent subsequently had spontaneous vaginal delivery without complication. A scheme for managing renal calculi in pregnancy is presented.

A retrospective analysis of 156 rigid ureteroscopic stone procedures in 145 patients revealed successful manipulation in 90%. The stone-free rate after adjunctive procedures was 95%. Access was achieved without balloon dilation in all but 18 patients. There were 24 perforations, occurring in 31% of proximal, 8% of mid ureteral and 8% of distal stone manipulations. Of the evaluable patients 63% underwent radiographic assessment for stricture disease, 75% at 6 months or more after the procedure. The stricture rate was 3.5% in all patients and 5.9% in patients with perforations. Of 37 patients evaluated for vesicoureteral reflux only 1 had reflux. Questionnaire followup was obtained for 74% of the patients (mean followup 2.6 years) and 32% felt normal within 3 days. Postoperative symptoms included flank pain (13%), renal colic (12%), pelvic discomfort (30%) and Double-J stent related complaints (49%). Of the patients 15% have reported recurrent stones. Ureteroscopy is effective and well tolerated, and it has minimal long-term complications.

Studies have demonstrated that 4% to 10% of patients with chest pain and acute myocardial infarction (AMI) are discharged from the emergency department. The patient with an atypical presentation of AMI is difficult to diagnose and has been demonstrated to have an associated increased risk of morbidity and mortality. A case is reported of a patient with AMI presenting to the emergency department with flank pain and tenderness, mimicking acute renal colic.

The diagnostic value of ultrasonography (US) and intravenous urography has been compared in a prospective study comprising 123 consecutive patients with severe acute flank pain of less than 72 hours' duration. Ultrasonography was performed transabdominally with a 5 MHz sector real-time transducer. Ureteral calculi were considered the final diagnoses in 46 patients, of which 35 with and 11 without accompanying hydronephrosis. Ureteral calculi were correctly diagnosed by US in 17 patients (sensitivity 37%). If hydronephrosis with or without calculus is included as a positive sign of ureteral calculus, a correct diagnosis was suggested by US in 34 patients (sensitivity 74%). We consider US to be a valuable method in patients with previous contrast media reactions, but recommend urography as the standard imaging method when renal colic is clinically suspected.

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.

A prospective study compared the diagnostic accuracy of sonography and excretory urography in determining the cause of acute flank pain in 61 patients. Forty-one patients had urinary tract stone disease. Of these, five had nonobstructing renal stones and 36 had obstructing stones. A correct diagnosis was made by urography in 85% and by sonography in 66%. Small stones at the ureterovesical junction were more accurately diagnosed by sonography (79%) than by urography (68%). In all the patients where sonography failed to detect the offending stone, the stone was calcified and evident on the plain radiographs. There were no false-positive diagnoses in the patients clinically judged to have passed a renal stone (nine patients) or whose pain was arising outside of the urinary tract (five patients). Neither sonography (17%) nor urography (50%) was accurate in diagnosing acute pyelonephritis in the six patients with this diagnosis. Although sonography is not as accurate overall as urography in acute flank pain, it is a viable alternative in those with recurrent renal colic due to stone disease and in the pregnant patient.

Five cases of renal arteriovenous fistulae are described: four after needle biopsy of the kidney, one due to intrarenal aneurysmal rupture. One fistula closed spontaneously, the other four patients were operated on and treated by nephrectomy. 243 other cases from the literature were reviewed. The clinical manifestations involve the cardiovascular (arterial hypertension, congestive heart failure) or the urologic (hematuria, renal colic, flank pain) systems. The diagnosis is usually made by flank auscultation (which detects a continuous sound) and by use of renal arteriograms. The causes of these fistulae are numerous: congenital or acquired from biopsy examinations, trauma, surgery, neoplasia, infection, aneurysmal rupture. The usual treatment of these fistulae is a nephrectomy but selective embolization or direct surgical repair make possible, with greater frequency now, renal parenchymal preservation.

Renal colic, defined as acute flank pain caused by the passage of a ureteral calculus, is a common condition, but the correct diagnosis may not be apparent clinically. For decades, intravenous urography has been the test of choice for evaluating patients with suspected renal colic. Recently, unenhanced (non-contrast) helical CT has been shown to be an accurate and highly effective examination which can be used instead of intravenous urography. In this article, the technique is reviewed in detail, including its advantages and potential pitfalls.

In a retrospective analysis the results of extracorporeal shock wave lithotripsy (ESWL) treatment were evaluated in patients with renal stones according to calyceal localization of treated stones. The 198 patients who underwent ESWL with the Dornier MPL 9000 were analyzed for success rate, complication rate, residual fragments, regrowth and recurrence rates. Totally 210 calyceal calculi located in different portions of the kidney have been comparatively evaluated. No major complications were noted during or after ESWL. Some minor complications such as flank pain, renal colic, haematuria were observed. Flank pain was observed during ESWL treatment especially in patients with upper calyceal stones. Although stone-free and residual fragment rates were similar in pelvic, upper and middle calyces, patients with lower calyceal and pelvicalyceal stones had high residual fragment rate and lower stone-free rate. Patients with stones in the lower calyces or pelvicalyces had high recurrence and regrowth rates (p < 0.05). ESWL has been considered as the optimal treatment modality for most upper urinary tract calculi. It is especially effective in patients with pelvic, upper and middle calyceal stones. Patients with lower calyceal stones often failed to eliminate the fragments, hence had high recurrence and regrowth rates.

The case of a patient with acute onset of flank pain and hematuria is presented. Initial therapy was directed toward relief of pain believed to be caused by renal colic. It was not until the patient developed atypical features that the true diagnosis, ruptured renal angiomyolipoma, was discovered. The case and discussion emphasize the need to carefully consider a complete differential diagnosis when evaluating patients with flank pain and hematuria who have atypical clinical features or an atypical course.
