Epidermoid cyst of the kidney is a rare entity. In the case here presented, epidermoid cyst was an incidental finding at urography performed in a 67-year-old man in connexion with splenectomy for polycythaemia. The cyst was interpreted as an old tuberculous focus. Two years later partial nephrectomy was performed because of repeated attacks of renal colic and signs of recurrent pyelonephritis. The diagnosis of epidermoid cyst was not made preoperatively in this case, or in the cases described in the literature.

A history of phenacetin abuse has been found almost three times more frequently among subjects diagnosed on clinical and functional grounds as suffering from chronic pyelonephritis than among those suffering from other renal diseases or among non-renal controls. The chronic pyelonephritis in subjects admitting phenacetin abuse has been usually characterized by a more frequent intense bacteriuria and leucocyturia, by a slightly more frequent haematuria, history of renal colic, presence of stones and more rapid downhill course of glomerular filtration rate than in subjects without phenacetin abuse. A sterile lesion also without any past evidence of infection was observed only in subjects with the heaviest analgesic abuse. The discontinuation of the abuse in 5 subjects led to an improvement of the renal function.

Renal colic always involves pelvic hypertension and severe urodynamic disturbances which result in fornical reflux, urine leakage to renal interstitial tissues, to tissues of the renal sinus, and sometimes to the retroperitoneal space. If the urinary tract is infected, renal colic may lead to acute pyelonephritis and generalized infection, as well as to bacteriemic shock. Of great importance in the origin of retroperitoneal fibrosis are fornical refluxes. Since renal colic is the most frequent cause of pyelorenal reflux, patients with renal colic should be promptly given appropriate treatment aimed at eliminating or at least lowering pelvic hypertension.

A review of 22,971 pregnancies from 1969-74 reveals that the reasons for requesting excretory urography were renal colic of pregnancy 11, pyelonephritis 8, renal contusion 2, threatened abortion 1, and suspected degeneration of fibroid 1. The final diagnoses were similar except that two patients with torsion of ovarian cysts and a renal calculus were discovered. The only intravenous pyelographic examination that was decisive for diagnosis was in a patient with a ureteric calculus. Careful clinical correlation should reduce excretory urography during pregnancy.

The angiographic findings in 13 patients with renal hemangiomas (one pararenal) are presented. The material suggests, contrary to earlier reports, a predominance for the female sex and the right kidney. Nine of the patients had macroscopic hematuria, of which five had renal colic. Obstruction was found at urography in seven cases. Renal angiography is the definitive diagnostic procedure and should be performed in all cases of unexplained macroscopic hematuria. Diagnosis may eventually be improved by pharmacoangiography or by hemodynamic studies using a dye dilution technique, as small arteriovenous shunts may remain undetected at angiography. Cardiac decompensation was not noted in our material, even though arteriovenous shunting within the hemangioma was seen in eight cases, suggesting that the shunt flow in renal hemangiomas usually does not reach levels high enough to impair the general circulation. Hypertension was present in only one patient, attributed to chronic pyelonephritis. Hematuria disappeared in all nine patients operated upon.

The authors observed 812 patients with nephrolithiasis who underwent 876 sessions of shock-wave lithotripsy on Sonolith-3000 lithotriptor supplied with an ultrasonic system of the stone localization. The size of nephroliths ranged from 0.7 to 4.2 cm. Large-size nephroliths required repeated sessions and pretreatment establishment of the stent. The procedure proceeded without anesthesia. Subsequent renal colic was reported in 126 (15.5%), an exacerbation of pyelonephritis in 45 (5.5%), subcapsular hematoma in 4 (0.5%) of the patients. 790 patients showed clinical response (97.3%), with a complete destruction of the stone in 446 (54.9%) and partial one in 344 (42.4%) cases. 27 subjects were treated in outpatient setting. According to the authors, lithotripsy is contraindicated in urinary tract obstruction below the stone, renal failure, chronic pyelonephritis in the active phase of inflammation, marked impairment of cardiac rhythm.

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.

Acute abdominal pain during pregnancy can be of urologic origin. Hydronephrosis of pregnancy can be complicated by symptomatic renal colic, pyelonephritis, and secondary renal abscess formation. In this report, rupture of a hydronephrotic kidney with retroperitoneal urinoma formation was treated by retroperitoneal drainage and internal ureteral until a term delivery was achieved. However, if severe renal hemorrhage accompanies renal rupture, surgical exploration of the kidney with partial or complete nephrectomy may be necessary.

The authors report 17 personal cases of lithiasis of the upper urinary tract discovered in the course of pregnancy. They discuss the diagnostic and therapeutic problems, taking into account the double risk of mother and foetus. The essential diagnostic sign is renal colic, with or without fever. Spontaneous excretion of these calculi is possible, but in 8 of the 17 cases, a ureteric catheter had to be passed or an operation was required. Neither the delivery nor the health of the infants delivered seemed to be harmed by this renal calculi disease. The authors recall that the most common cause of non-obstetrical abdominal pain in the course of pregnancy is in fact urinary calculi. The incidence is about 1 cases of lithiasis per 1,000 pregnancies. It appear that a physiological hyperparathyroidism of pregnancy is responsible for a hypercalciuria which could be a factor favouring the development of lithiasis during pregnancy. The important point is to know how to distinguish those forms of pyelonephritis of pregnancy which are due to a stone obstructing the upper urinary tract, as any purulent retention in the upper tract can lead to a pyonephrosis, a bacteraemia or even a septicaemia. The presence of the foetus makes interpretation of a plain abdominal film difficult. In any case, its indication is questionable, whenever the urine is septic, particularly with Proteus.(ABSTRACT TRUNCATED AT 250 WORDS)

Prompt, thorough evaluation is needed when patients present with symptoms of renal colic, acute urinary retention, prostatitis, pyelonephritis, and other urologic emergencies. Primary care physicians have an important role in initial workup and treatment. Once the diagnosis is determined, urologic consultation may be necessary for definitive treatment.
