A case of renal adenocarcinoma localized to the isthmus of a horseshoe kidney is described. We underscore the importance of complementary US and/or CT to urography to study the acquired pathologies of the horseshoe kidney because the pyelocaliceal distribution of these kidneys may not facilitate correct identification of certain space occupying lesions. The angiographic study is considered essential for planning surgery for this type of lesion.

Herein we describe a patient with noninsulin dependent diabetes mellitus who developed acute anuric renal failure following eye surgery. This condition, ascribable to diabetic neurogenic bladder and probably to the use of anticholinergic agents, improved following placement of a urethral catheter. The physiopathological mechanisms and treatment are discussed.

Two cases of stone formation on double J ureteral catheter are described. Resolution was achieved by ESWL in one and by simple endoscopic removal in the other case with calcification in the distal J. The appearance of calcareous encrustation is frequent and depends on various factors especially the length of time the catheter is left indwelling, urinary stasis and infection. The efficacy of extracorporeal lithotripsy in resolving this complication is discussed.

The most frequent method utilized in the treatment of bladder diverticula is by open surgery using the extravesical, transvesical or combined approach. The endoscopic techniques consisting of electrocoagulation of the diverticular mucosa alone (Orandi) or opening the diverticular neck by electroresection (Post-Vitale) constitute a therapeutic alternative not widely used to date. We have attempted to combine both techniques and, since 1985, we have treated 21 patients with bladder diverticula via the transurethral approach using the following technique: 1. ⋯ In our view, failure was due to the fact that treatment of the diverticulum had not been combined with prostate resection which the patient refused. The technique is described and the indications and possible complications are discussed. The results achieved by the authors indicate that this technique should be used more widely.

We report on 26 patients with sustained penile erection from spinal anesthesia following the classical technique using 20 mg bupivacaine at 0.25% that were treated by intracavernous injection of 10 mg ethyladrianol. Complete detumescence was achieved in 23 (88.4%); partial detumescence, which permitted transurethral surgery, was achieved in 3 patients (11.6%). ⋯ All patients presented easily controllable arterial hypertension. This is a simple, easy and practically risk-free technique that has the advantage of achieving a high response rate thereby permitting surgery.
