[A metabolic study of urolithiasis. Specificity, sensitivity, efficacy and reproducibility].

A preliminary diagnosis of the disease responsible for the stones is essential to allow appropriate medical treatment of renal stones. In this paper, the authors describe their diagnostic and treatment protocol based on computer-assisted urinary metabolic analysis. 413 subjects, divided into four groups, were prospectively evaluated to calculate their specificity, sensitivity, reproducibility and efficacy and to demonstrate the usefulness of this protocol.

[Our experience in the treatment of cystine lithiasis].

Contribution of six cases of patients with cystinic lithiasis, diagnosed and treated at our centre. Analysis of pathophysiological mechanisms, key data for their diagnosis and current aspects of treatment, as well as a review on past and recent literature on this disease.

[Conservative treatment of Wünderlich syndrome in a functional monorenal patient].

Presentation of one case of Wünderlich's syndrome secondary to spontaneous mesorenal fracture due to renal angiomyolipoma. In our case, the therapeutical approach is based in the need to preserve the functional renal unit. Wünderlich's syndrome or spontaneous perirenal haematoma can occur for a variety of causes, the most frequent ones being renal adenocarcinoma and renal angiomyolipoma. The latter is a hamartoma made up of three different tissue lines: smooth muscle cells, blood vessels and adipose tissue. Based on our case, we discuss the clinical, prognostic and therapeutical aspects related to renal angiomyolipomes.

[Ureteral lithiasis. Analysis of 3 series].

Presentation of our experience on 1000 cases of ureteral lithiasis treated over the last five years with ESWL, ureteroscopy and ureterolitotomy, distributed in three series of 396, 265 and 339 cases respectively. In the first series (396 cases), lumbar ureter calculi were treated with ESWL (dornier HM3) and iliopelvian calculi with ureteroscopy. In the second series (265 cases), all calculi were treated with ESWL (Siemens Lithostar). The third series was in turn subdivided in three groups: in the first group, comprising simple ureteral calculi, 'in situ' ESWL was performed; in the second group, of lumbar ureter complex calculi, ESWL was performed assisted by simple endourological techniques; ureteroscopy was performed in the third group, iliopelvian ureter complex calculi. Calculi characteristics (site, size, consistency and number), excretory tract and renal function, designated as CEP/LTS-X were assessed. These parameters allow us to grade ureteral lithiasis in Types I, II and III. A comparative study of the results in the three series was made reaching an overall conclusion that simple or Type I ureteral lithiasis can be treated with 'in situ' ESWL as first choice; in Type II or lumbar ureter complex lithiasis, 'in situ' ESWL is insufficient and other endoeurological support techniques are required, while in Type III, iliopelvian ureter complex lithiasis, ureteroscopy should be recommended.

Endoscopy

[Distal tubular renal acidosis with nephrocalcinosis].

Nephrocalcinosis and distal tubular acidosis are two infrequent processes caused by several etiologies which can present in association. This paper describes a clinical case of tubular acidosis and explains the differential diagnosis of both entities.

Acidosis, Renal Tubular

[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.

Chronic Disease

[Double-J ureteral catheter: its application in patients with complex renal lithiasis as a support measure during extracorporeal lithotripsy. Analysis of 441 consecutive cases].

Between August, 1986 and February, 1988, double J ureteral catheters were placed in 441 renal units of 419 patients (22 were bilateral) with complex renal stones prior to ESWL. Catheter placement was achieved in all but 3.8% of the cases using several techniques, mainly via the retrograde route. Placement of the double J catheter was indicated in almost 75% of cases with a large stone mass (staghorn or pseudo staghorn). Only 11% of post-ESWL "Steinstrasse" were obstructive; of these, 80% resolved spontaneously. The complication rate was 21%. Most of these cases were mild complications. All cases were resolved satisfactorily. We believe that the double J catheter is useful in patients with complex renal stones. Placement of a double J catheter involves a simple maneuver with a low morbidity. It aids ESWL, reduces complications, and avoids more important endourologic maneuvers.

Adult

[Current treatment of ureteral lithiasis].

The treatment of ureteral lithiasis has undergone a revolution since the arrival of new techniques offering different therapeutical choices for which time is gradually elucidating the indications for each of the new procedures; although, to a large extent, a degree of controversy still persists. This paper reviews the different methods for ureteral lithiasis; spontaneous ejection and medical treatment, surgery, early endoscopic manoeuvres, backward and forward urethroscopy and, finally, extracorporeal lithority. This therapeutical experience in 3 series of ureteral lithiasis addressed with different criteria are revised together with 182 obstructive calculi of the lumbar ureter. We believe that grading the ureteral calculi according to their anatomical and functional features improves the results, since improved adjustment can be achieved for the indications of the various methods. Also it is noted that support endourology for extracorporeal lithotrity does not improve the results of treatment in lumbar calculi under 2 cm, and therefore our current approach is towards "in situ" treatment without complementary manoeuvres. Finally we show the therapeutic algorithm we are following actually to manage ureteral litiasis.

[Migration of an intrauterine device. An unusual cause of bladder foreign body].

The origin of vesical and lower urinary tract foreign bodies is very wide, the specialized literature descriptions ranging from urethral dilators to coffee spoons handles through wires, cables and surgical instrumentation. The most frequent entry route of foreign bodies to the lower urinary tract is through the urethra usually by self-introduction or during transurethral surgical procedures. Another access route is that occurring during open or traumatic surgical manoeuvres. Less frequent is that the foreign body migrates from another anatomical structure. These patients present an heterogeneous clinical picture which depends on the location of the foreign body in the urinary tract. Thus, it can be acute if located in the urethra or subacute or chronic if found at vesical level.
