[pT1G3 bladder carcinoma: parameters of a correct therapy].

Between 13.8% and 27% of all superficial bladder cancers are represented by pT1G3 neoplasm. In the Department of Urology of Policlinico S. Marco-Zingonia, between February 1988 and June 1994, we treated 22 patients suffering for pT1G3 bladder tumor. TUR-B has demonstrated to be a good approach for treatment of superficial bladder cancer, with low morbility; on the opposite side, we have to underline the high rate of recurrence and of progression of the urothelium disease. Now a day our best approach for the treatment of pT1G3 bladder tumor is represented by radical cystectomy supplied by chemotherapy.

[Orthotopic ileal neobladder of the Emikock type: technical points and functional results].

Ileal orthotopic neobladder represents, nowadays, the best urinary diversion after cystectomy. Emikock procedure was performed, in our institution, in 26 patients with bladder cancer T2-T4. At 6-60 months of follow-up 3 pts were died with local or at distance neoplastic recurrence, 2 were alive with neoplasms and 21 were NED. Nocturnal continence was good in 22 cases (88%) and only 3 patients were obstructed because of pseudodyssynergia in 2 and stricture in 1. Emikock neobladder even if needs a longer surgical time than other procedure and a long ileal tract is almost free from severe metabolic disorders. This technique offers a good protection of high urinary tract because of antireflux nipple and avoid the uretero-intestinal stricture. It not feasible, now, to know the functional trend of this reservoir on the long term. Adequate postoperative training is recommended to avoid the pseudodyssynergia and functional obstruction of reservoir.

[Iatrogenic obstructive azoospermia].

Obstructive azoospermia is a common cause of sterility in men. In the past infection played an important role in the aetiology of obstructive azoospermia. Recently, however, the aetiology of obstructive azoospermia appears to be changing. So iatrogenic obstructive azoospermia has reached an important role in the field of obstructive azoospermia. In this work we show international literature about iatrogenic obstructive azoospermia. Unfortunately it is poor, in spite of an interesting item. We divided iatrogenic obstructive azoospermia into six groups, considering the possible anatomical site of obstruction. So we show the possible damages at the different levels: testis, epididymis, vas deferens, seminal vesicles, prostate and ejaculatory ducts.

[Benign prostatic hypertrophy. Optimized diagnosis].

The optimal diagnostics of B.P.H. must be efficient, cheap and of spare invasiveness either physical than psychological. The optimization of diagnosis is the obtainment of high quality in the services provided, matched to a correct and shrewd utilisation of resources. To optimise a diagnosis efficiency is necessary, which means the largest degree of standardization of diagnostical procedures, with responsible management of economical factors. A course of standardization, cause his excessive simplification, cannot shared to a lot of Urologists, because in their opinion there is a risk to lose informations in every single patient, but is essential to use a universal language that make easy the comparison with patients and with results whether in order to clinics or trails. The standardisation of diagnostics consists to obtain the maximum of informations from present methodology and that is possible to realize in two way: improving the technique of execution and including the diagnostic test in the appropriate point of algorithm.

[TURP: what and when. Indications, results, complications: our experience].

Transurethral resection of the prostate (T.U.R.P.) has indeed replaced open surgery in the great majority of cases, particularly when the gland is estimated to weight 50-60 g or less. After prostatectomy the patient resumes a normal voiding pattern and obstructive symptoms quickly disappear, although irritative symptoms tend to persist for some time.

[Radical prostatectomy: our experience].

Between July 1989 and June 1994 32 men (48-73 years old) underwent radical retropubic prostatectomy for prostate cancer. 26 patients (70%) presented with symptoms of bladder outflow obstruction. The primary tumour was understaged preoperatively in 5 patients (15.5%). At follow-up (6-66 months, average 24) significant urinary incontinence not occurred in our patients; sixty-two per cent reported a substantial problem with reduced or absent erection. A total of 23 patients was free of clinical or biochemical progression, observed in 28% of cases as distant or local progression. Radical prostatectomy is being performed with increasing frequency: trends in morbidity have been identified.

[External devices: for which patients?].

Vacuum therapy is a reversible, non-invasive form of treatment for partial impotence, with great success in USA. The story of vacuum therapy begins about 1960, when Osbon developed a vacuum tumescence device which he personally used for more than 20 years. The device was made commercially available many years ago and has been marketed under several names. The newer systems have incorporated a negative pressure pump to achieve vacuum. Osbon's system was patented in 1983, sale is permitted by the U.S. Food and Drug Administration, and it is available by prescription only. More than 10,000 units have been sold. There are four different types of vacuum therapy: 1) loading cone + constriction band; 2) external splint + negative pressure; 3) Negative pressure + constriction band; 4) Negative pressure + intracavernous injections, without the use of constriction band. Each basic system will be described. The authors make a comparison between the use of negative pressure devices plus tension band and the use of negative pression devices without tension band (plus C.I.D. with vaso-active agents). In the second case there's a sort of synergistic action between vaso-active agents and vacuum therapy, representing a sort of "vaso-active exercise" of the erectile tissue. There are no absolute contraindications to use of external penile devices and potential contraindications are few. The external penile devices described represent a reversible therapeutic modality that can augment an inadequate erection and they should prove useful in any man who needs erectile enhancement. These devices appear to be particularly effective in men with partial impotence in whom only erectile enhancement is needed.

[Penile nuclear magnetic resonance (NMR)].

Nuclear Magnetic Resonance (NMR) is a new diagnostic technique with great opportunities of application in the field of the penile pathologies. A new interest for this diagnostic technique was born when the use of vasoactive agents, like papaverine or PGE1, and the use of para-magnetic contrast agents, like gadolinium, were introduced. The introduction of dynamic NMR in andrology allowed a better definition of anatomical details and a better knowledge of penile micro-circulation. N.M.R. is showing a great diffusion, because of a little invasiveness (X-rays are not used in this technique). The Authors show a wide spread of possible applications of NMR in penile pathologies, helping in the interpretation of the images. In conclusion the authors describe NMR as a diagnostic technique with great possibilities of improvement, even if the high costs don't allow a better diffusion until now.

[Urologic laparoscopy: preliminary experience].

Laparoscopy is a safe and reliable procedure for treatment of cryptorchid testicle, varix ligation, staging of lymph nodes in prostatic and in bladder cancer. Recently this procedure is adopted in management of renal cysts. From 2/92 to 7/92, we performed laparoscopic assessment in 31 patients: in 15 cases for varicocelectomy, in 9 for renal cysts, in 2 for lymph nodes dissection, in 3 for preoperatory evaluation, in 1 for unpalpable testicle and in 1 case for ileal perforation in orthotopic neobladder. In 1 case the procedure was unsuccessful because of damage of the spleen. All the patients were mobilized within 1 day postoperative treatment and discharged within 3 days. There are many present and potential application of laparoscopic surgery in urologic pathology, but we think that this technique must be carefully applied in order to avoid complications.

Use of the fiberoptic bronchoscopy in the elderly.

The authors emphasize the primary role fiberoptic bronchoscopy has for diagnostic and therapeutic purposes in the elderly affected by pulmonary disease. Safety, efficacy and tolerability of the method in the elderly are obtained through a preliminary and careful evaluation of the patients, either clinical or instrumental.

[Intracavernous infusion of drugs].

In 1982 Virag presented the initial experience of use in diagnosis and treatment of impotence. PGE1 has been showed a safe and effectiveness drug. From september 1989 to october 1991 210 patients with erectile disorders were managed by I.C.I. with PGE1 with minimal side effects.

[Endocavernous drug infusions revisited].

From the beginning of the eighties papaverine was well established as the drug of choice for diagnosis and management of vasculogenic impotence. In the second half of the eighties decade many authors referred on experimental use of PGE1 in erection disease. PGE1 has been showed a safe and effectiveness drug. During the period September 1989-October 1990 at our Institution 98 pts. with erectile disorders were managed by I.C.I. with PGE1. Out of 98 cases 88 had success. Prolonged erection occurred in 4 pts. (4.2%). 10 pts. showed only tumescence. So there are been treated by I.C.I. with combined papaverine and PGE1 with better results. No side effects were formed in 10 pts. managed by self-injection of PGE1.

Urinary NAG excretion after anesthesia-free extracorporeal lithotripsy of renal stones: a marker of early tubular damage.

Second generation lithotripters require a higher number of shocks per session as well as an increased rate of secondary treatments for complete stone disintegration compared to the original spark gap lithotripter. The clinical relevance of biological side effects caused by such treatment are less known. We evaluated urinary excretion of N-acetyl-glucosaminidase (NAG) before and after lithotripsy in 50 patients treated with a low pressure spark gap lithotripter (Dornier HM3) and in 36 patients treated with a piezoelectric lithotripter (Wolf Piezolith 2200) in an attempt to evaluate their side effects on renal tissue. The urinary excretion of NAG increased after both spark gap lithotripsy using the modified HM3 and piezoelectric lithotripsy. These changes may be associated with slight tubular damage that would occur after anesthesia-free lithotripsy in patients subjected both to a high number of shocks and to secondary treatments.

[Complications of percutaneous litholapaxy].

Percutaneous nephrolithotomy has been proved an efficient management of renal calculi. We report, in present review, the complications of PCNL procedure referred by several authors and our casistic since 1985. Major complications occurred in 3-6% of treated patients: severe bleeding, arteriovenosal fistulas, haematoma perirenal, water syndrome, sepsis, DIC, etc.). Nephrectomy was necessary in less than 1% of reported cases. 5 patients died for complications related to PCNL. Early complications occurred during the percutaneous puncture, tract dilation and lithotripsy. Postoperatively bleeding at the time of nephrostomic tube removal was reported in 0.5-1% of cases. Late sequelae of PCNL: stricture, fistulas, renal damage, renal function loss, high lithiasis recurrence rate were reported rarely. We, herein, believe PCNL is a safe and effective procedure with minimal rate of complications and late effects, according to other important authors.

[Complications and limitations of transurethral prostatic resection: retrospective study of 366 patients].

In present paper we report our experience on 366 patients underwent to transurethral resection of prostate from January 1988 to January 1990. All patients were controlled by uroflowmetry and retrograde plus minctional urethrography, with evaluation of the possible immediate and latest complications. Among the latest complications, the most representative had been urethral stricture, occurred in 24 patients (6.5%) according with international literature. We considered also various iatrogenics factors (operator experience, endoscopic time, catheter section, catheter permanence time, use of lubricator, presence of catheter before TURp, preventive Otis urethrotomy). From our study rises out that the most important risk factors are: a) catheter permanence time; b) TURp without preventive Otis urethrotomy.

[The Wolf piezolith 2300 lithotriptor: a technical note].

In the Piezolith Wolf 2300 lithotripter, shock waves are generated by about 3000 piezoceramic elements aligned on a self-focusing spherical disk. No ECG-recording is required. Stone localization is obtained by two 4.5 MHz sector ultrasound scanners. Acoustic coupling is performed by a partial water bath. The focal region (pressure higher than P + 12) is only 11 X 3 mm. The positive peak pressure ranges by 300 two 1050 bar. The large exposure of the shock front causes low pressure at the skin level and gives quite painless treatment.
