[Treatment of ureteral lithiasis with ureteroscopy].

We describe our experience and the results achieved in the treatment of ureteral lithiasis by ureterorenoscopy. Our results show the usefulness of this technique for calculi in the lower ureter. Furthermore, it can be used in combination with ESWL and PCN. Calculi in the lumbar ureter can be pushed up into the kidney for subsequent treatment with ESWL or PCN. We analyzed the results of 133 URS procedures that had been performed to treat calculi in the ureter. URS was used in combination with ESWL in 20 patients. Analysis of the success, failures, and complications of URS demonstrate the usefulness and efficacy of this procedure in the treatment of urinary calculi. Complications can be resolved with no life-threatening risks. The number of complications will decrease with our increasing expertise in the use of this technique.

[Giant urethral lithiasis].

We present a case of giant urethral lithiasis, housed in the penile urethra. Owing to the scant incidence of this pathology and its rarity, as well as the small number of bibliographic references found, we believe it of interest to offer this fresh case.

[Milk of calcium lithiasis. Crystallographic study].

We performed a crystallographic study of two cases of milk of calcium lithiasis. Dust from the specimens were studied by x-ray diffraction and thin layer light microscopy. Analyses of the different morphological types and their layers revealed these to be comprised of wewellite and calcium phosphate, except one with pure wewellite in its core and cortex.

[Extracorporeal shockwave lithotripsy (ESWL) as monotherapy using the Dornier HM-3 in staghorn kidney lithiasis. Effectiveness of the use of a double J catheter].

The authors reviewed 110 cases of staghorn calculi (71 complete and 39 incomplete) from 693 cases of lithiasis that had been treated over a 15-month period at their hospital with the Dornier HM-3 lithotripter. Good results were achieved in 72.2% of the cases. One patient had a fall in hematocrit and a subcapsular hematoma which evolved well. Of the patients who did not have a double-J catheter, 33.6% had steinstrasse versus 27.9% of those who did. Because the complication rate is lower when double-J catheter placement is combined with ESWL this approach is recommended instead of PCN + ESWL.

Pancreatic lithiasis: a rare cause of gastrointestinal hemorrhage.

The rare instance of a gastrointestinal hemorrhage caused by a lithiasis of the duct of Wirsung is described. The world literature records only 13 other cases. Pancreatic calculi cause hemorrhage by either migrating through the pancreatic parenchyma to perforate the duodenum, ulcerating the vessels of the periductal parenchyma, or rupturing the pancreas. The usual sign of this complication of chronic calcifying pancreatitis, difficult to diagnose, is repeated gastrointestinal hemorrhages and sometimes pain, as in epigastric colitis. The immediate therapy is control of the hemorrhage. With transcatheter occlusive techniques, radical surgery can be postponed until it is more tolerable.

[Value of extracorporeal shockwave lithotripsy in the treatment of urinary lithiasis in children].

We report our experience with extracorporeal lithotripsy (Dornier HM3) in a series of 26 children with a mean age of 11.6 years, treated for 3 1/2 years. 12 children (46%) had a previous history of calculi and 7 (27%) had already undergone surgery on the same side. Treatment requires two transducer investigations before lithotripsy. With the exception of minor modifications the technique is the same as in the adult. Three (9.7%) postlithotripsy complications were noted, requiring 2 drainage procedures to be carried out on the urinary tract. At 3 months, the success rate (no residual calculi on the plain abdominal film) was 60.7%. This study confirms the efficacy of lithotripsy in the treatment of urinary lithiasis in children.

[Diagnosis of choledocholithiasis and residual lithiasis. Ultrasonic postcholecystectomy].

246 patients with proven common bile duct stones at surgery were studied in order to establish the accuracy of ultrasound scanning in detecting choledocholithiasis and to compare the sensitivity of real-time examinations with those performed by a static scanner. The detection of choledocholithiasis by real-time ultrasound was 45.6% compared to 26.3% for the examinations performed with a static scanner. A dilated common bile duct was detected in 83.6% using real-time scanning compared to 70.3% using a static scanner. When the common bile duct was not dilated ultrasound was unable to detect the stones. Real-time ultrasound detected 66.6% of the patients with residual choledocholithiasis compared to 23.5% of patients examined by a static scanner. Our results show that real-time ultrasound scanning is a very useful screening method in detecting choledocholithiasis and residual lithiasis.

[Non-surgical treatment of biliary lithiasis].

The usefulness of the treatment of the biliary lithiasis with chenodeoxycholic and ursodeoxycholic acids is discussed, including the selection of patients, optimal doses, adverse effects and recurrence of stones. New treatment with methyl tertiary butyl ether and extracorporeal shock wave lithotripsy (ESWL) is evaluated. Endoscopic procedures, eventually combined with ESWL, represent the preferred treatment for patients with bile duct stones.

[Lithiasis of accessory salivary glands].

With respect of three new cases which may be joined to five others previously reported, the authors emphasize that lithiasis of the minor salivary glands is more ignored than uncommon. That misreading is the consequence of the ordinary X-ray transparency of these little calculus. Diagnosis is grounded on the finding of the enlarged orifice of the gland and its suppuration. Treatment may be limited to the only extraction of the calculus. Prognosis is excellent: multiple forms and relapses are rare.

[Lithiasis of the common bile duct and transduodenal papillosphincterotomy. Analysis of our cases].

The results obtained from 1978 to 1987 with the use of transduodenal papillosphincterotomy in bile duct lithiasis are reported. The operation was performed on 126 patients and produced 4.7% immediate mortality. The indications and the most frequent post-operative complications were studied. Routine intra-operative cholangiography had been carried out. The long-term results were very good in 86% of the cases, average in 13% and poor in 1%. Provided one limits its indications to cases when it is really necessary, papillosphincterotomy does not involve a higher risk than other biliary operations.

[Biochemical profile of primary hyperparathyroidism. Comparative study with hypercalciuric renal lithiasis].

Primary hyperparathyroidism (PH) is now considered a common condition. Its frequency and the deleterious long-term effects of hypercalcemia make a correct diagnosis mandatory. We attempted to evaluate the usefulness of the indexes of parathyroid function and hormone measurements more commonly used in the diagnosis of PH. To this end we studied 64 patients, distributed in three groups: group with PH, group with hypercalciuric renal lithiasis (HRL) and control group (CG). The results were evaluated with a test of comparison of means and a stepwise discriminating regression analysis. The 8 most useful measurements to differentiate PH from HRL and CG were serum calcium, corrected serum calcium, serum phosphorus, fasting calcium excretion (FCE), maximal tubular calcium reabsorption (MTCR), maximal tubular phosphate reabsorption (MTPR), osteocalcin, PTH half molecule (PTH-HM) and 1,25-dihydroxyvitamin D. The 3-variable and 4-variable groups with a highest discriminating ability were: serum calcium, FCE and PTH-HM, and serum calcium, FCE, PTH-HM and MTPR. We think that the measurement of these four variables is the most adequate strategy for the diagnosis of PH.

[Residual lithiasis of the common bile duct. Surgical or endoscopic treatment?].

The authors report their experience concerning residual lithiasis of the common bile duct, while trying to define the respective place of surgery and endoscopy in this condition. There is a clear female predominance in their series, the mean age being 41 years. The indications for surgery and endoscopy are discussed and the means of prevention are reviewed.

[Chronic obstructive renal lithiasis. Extracorporeal lithotripsy or percutaneous renal surgery? Analysis of 2 series].

Experience has demonstrated that obstructive renal calculi with inferior infundibulocaliceal dilatation is not an indication for extracorporeal shock wave lithotripsy due to a high incidence of residual fragments in the lower calyx. These fragments are generally not spontaneously passed and become compact and form a new stone. We analyzed two groups of patients: 56 had been submitted to ESWL, and 53 to PCN. The results show that for obstructive renal lithiasis with dilatation of the lower calyx treatment is by percutaneous renal surgery first. This approach permits doing an ESWL procedure if stone fragments are observed in the early post-PCN radiologic work up. Similarly, if ESWL as monotherapy fails, we can resort to PCN.

[Changes in the parameters of hepatic function in biliary lithiasis].

Our study investigates liver involvement serum parameters in 71 subjects with cholelithiasis and choledocholithiasis, without primary liver diseases. As a control group 118 healthy subjects were studied. All patients have been examined for serum transaminases, alkaline phosphatase and gamma-glutamyl-transpeptidase, total bilirubin and for liver enlargement. The results point out the presence of increased alkaline phosphatase and gamma-glutamyl-transpeptidase levels in more than half examined patients, and in nearly half of those without hyperbilirubinemia. This fact confirms that the existence of biliary lithiasis itself (even if limited to gall-bladder, in absence of jaundice) may account for the occurrence of a subclinical cholestatic liver impairment, that should be carefully considered in long-term prognosis of these patients.

[Milk of calcium renal lithiasis: uro-echographic evaluation].

From the fortuitous observation of a rare case of "milk of calcium" lithiasis in a renal calyceal diverticulum, the authors, having examined the etiopathogenetic implications of the disease and having considered the problems of differential diagnosis, discuss whether urography and sonography are a valid means of making a correct diagnosis and the consequent implications of a therapeutic nature which this pathology would involve.
