We report a case of bladder leiomyosarcoma which occurred in a 22-year-old female who had been treated with cyclophosphamide for a period of 68 months for retinoblastoma diagnosed at 18 months postpartum. Partial cystectomy was performed. Forty-two months after the operation she is tumor-free.

Squamous penile carcinoma is an uncommon neoplastic disease with an incidence of one in 100 000 men per year in Western countries. The role of penile-sparing treatment represents one of the three main issues in management of squamous carcinoma of the penis. Most authors consider conservative therapy as an indicated alternative treatment to partial or total penectomy in small size, low stage and grade tumours. At present, external or interstitial beam radiotherapy and lasertherapy represent the best available conservative therapeutic approaches. Another issue is the role of prophylactic inguinal lymphadenectomy in patients with negative palpable nodes. An early inguinal lymphadenectomy is indicated especially in patients with a high occult nodal micrometastases risk (G3 and pT2-4). The third point of discussion is represented by the use of chemotherapy in patients with metastatic disease. In this stage of disease, polychemotherapy with cisplatin, methotrexate and bleomycin seems to be more effective. The small number of patients investigated and the rapid evolution of the disease make it extremely difficult to carry out suitable perspective studies.

In the last decades incidence rates for renal cell carcinoma have been constantly increasing, especially in western European and Scandinavian countries and North America. Several epidemiological studies observed an increased relative risk of this tumour linked with some exogenous and/or environmental factors. The following exposures have been more consistently associated with renal cell carcinoma: tobacco smoking; occupational exposures (asbestos, aromatic hydrocarbons, chemical solvents); dietetic factors such as high energy intake, consumption of fried meats and poultry, and reduced intake of fruit and vegetables; iatrogenic factors such as analgesics and amphetamines; common diseases like obesity and hypertension. An effective preventive strategy for renal cancer could be carried out reducing the exposure to such risk factors.

Objective: To assess our experience in the treatment and clinical outcome of bladder nephrogenic adenoma (NA) updating and reviewing the literature concerning this issue., Patients and Methods: From September 1976 to June 1999, bladder NA was diagnosed in 8 patients: 6 men and 2 women with a 3:1 male ratio, aged 26-80 (mean 58.3) years. Follow-up ranged from 4 to 194 (mean 93.5) months., Results: NA was associated with transitional cell carcinoma in 3 cases. Predisposing factors were assessed in all patients. Previous surgery of the lower urinary tract was detected in 5 cases: ureterocystoneostomy in 2, partial cystectomy in 1, repair of vesicouterine fistula in 1, and multiple urethroplasties in 1. Previous endoscopic treatments were carried out in 2 patients, transurethral resection of the prostate in 1 and repeated transurethral resection of the vesicle in the other. A history of intravesical instillation of bacillus Calmette-Guérin was assessed in 1 case. Patients complained of irritative voiding symptoms in 6 cases and hematuria in 2. Endoscopically, the lesions appeared polypoid and multifocal in 5 patients, and flat and single in 3. The lesions were removed endoscopically, providing relief of symptoms in all cases. Histopathology assessed the diagnosis of nephrogenic adenoma, detecting focal atypic cells in 1 case only. Five patients (63%) relapsed 2-24 months after management. Recurrences were also treated endoscopically., Conclusions: Clinical and endoscopic features of bladder NA are not specific, simulating urothelial carcinoma or chronic cystitis. Endoscopic management allows accurate histological diagnosis and provides long-lasting relief of symptoms. NA needs careful and long-term follow-up, because of the high risk of recurrences and the potential neoplastic degeneration of the metaplastic urothelium., (Copyright 2001 S. Karger AG, Basel)

Objective: To evaluate the independent predictive value of the nuclear grading system according to Fuhrman in relation to the disease-specific survival of patients with renal clear cell carcinoma., Material and Methods: 333 patients who underwent radical nephrectomy for renal clear cell carcinoma between 1983 and 1999 were evaluated. In all patients we retrospectively studied nuclear grading, average tumor size, multifocality, pathologic stage of primary tumor, vein invasion, lymph node involvement and distant metastases. The Kaplan-Meier method was applied to evaluate disease-specific survival rates. The log rank test was used to compare survival curves and for univariate analysis. The Cox proportional hazards model was used for the multivariate analysis., Results: Histologic grade was G1 in 83 cases (25%), G2 in 117 cases (35%), G3 in 110 cases (33%) and G4 in 23 cases (7%). Our data showed that nuclear grading according to Fuhrman is related to medium tumor size (p < 0.0001), pathologic stage of cancer (p < 0.001), venous system invasion (p < 0.001), lymph node involvement (p < 0.001) and distant metastases (p < 0.001). The disease-specific survival after 5 and 10 years was 94 and 88%, respectively, in patients with G1, 86 and 75% in patients with G2, 59 and 40% in patients with G3 and 31% in patients with G4 (log rank p value < 0.0001). Multivariate analysis showed that nuclear grading by Fuhrman has a prognostic independent predictive value (hazard ratio = 1.8461, p = 0.002)., Conclusions: Nuclear grading is an important independent predictive factor of disease-specific survival in patients with renal cell carcinoma., (Copyright 2001 S.

In this article, the authors analyze a syndrome first described by Creevy in the 1940s, which may occur during a transurethral resection of the prostate (TURP). The syndrome is characterized by cardiocirculatory and neurological problems due to rapid changes in intravascular volume and plasma solute concentrations caused by excess irrigating fluid absorption. This article reviews the available literature and reports on the experience of our clinic, a specialist department in the physiopathology, diagnosis, therapy and prevention of TURP syndrome.

Introduction: Adrenal masses discovered by imaging techniques for reasons unrelated to adrenal diseases are called adrenal incidentalomas (Al). The aim of this study was to find out the clinical outcome of 28 patients operated for incidentally discovered adrenal mass and to update the literature concerning this topic., Patients and Methods: From September 1976 to December 1999 we operated on 28 patients for adrenal incidentaloma. Adrenal masses were unilateral in 25 cases and bilateral in 5. Average age was 57 years (range 10-73). Hormonal study was performed in all patients. All patients underwent adrenalectomy by the transabdominal subcostal approach., Results: Histopathology assessed the adrenal masses as primary in 19 patients and secondary in 9. 24-hour urinary vanillylmandelic acid (VMA) excretion was elevated in 2 patients. Adrenal insufficiency was detected in 1 case. Average tumor diameter resulted 5.8 cm (range 2-17). Histopathologic features of primary adrenal masses included pheochromocytoma in 5 cases, cysts in 4, myelolipomas in 3. nodular hyperplasia in 2, tuberculous mass in 1, cortical adenoma in 1, extra-bone marrow hemopoiesis in 1, cortical carcinoma in 1 and neuroendocrine tumor of the adrenal medulla in 1. The 9 adrenal metastasis resulted by renal cell carcinoma in 7 patients, urothelial carcinoma of the upper urinary tract in I and primary renal lymphoma in 1. Average follow-up was 68 months (range 6-246). Patients alive were 18 (64%), deal 10 (36%). Of the 19 patients with primary adrenal tumors 16 (84%) were alive and disease free and 3 (16%) died (I for disease and 2 for reasons unrelated to the primary tumor). Of the 9 patients with adrenal metastasis 2 (22%) were alive (I disease free and I with progression of the disease) and 7 (78%) died for disease. Replacement therapy for adrenocortical hormones was given 5 patients., Conclusions: Management of Al need CT or MRI and hormonal investigation in order to detect malignancy and subclinical hypersecretory syndromes. Subclinical functional adrenal masses, single adrenal metastasis and primary nonhypersecretory adrenal tumors sized 4 cm are treated by surgery. A close morpho-functional follow-up is indicated for primary adrenal incidentalomas when nonhypersecretory and smaller than 4 cm.

Objectives: The prognostic value of tumor extension into the renal vein or vena cava is still a controversial issue. The aim of this study is to report our experience with radical surgery in patients with renal cell carcinoma (RCC) extending into the renal vein or subdiaphragmatic vena cava., Methods: We evaluated 142 patients with RCC involving the renal vein or inferior subdiaphragmatic vena cava. RCC had extended into the renal vein in 118 patients and into the inferior vena cava in the remaining 24. Radical nephrectomy was performed in all cases with renal vein invasion. Radical nephrectomy with cavotomy and tumor thrombus removal was carried out in all cases with inferior subdiaphragmatic vena caval invasion. Cause-specific survival was calculated by means of the Kaplan-Meier method. The log rank test was used for survival comparisons and univariate analysis., Results: The 5- and 10-year cause-specific survival rates were 51.5 and 39%, respectively, in the group of patients with tumor extension into the renal vein and 33.4% in those with inferior vena caval involvement. In 52 patients (44%), RCC extended only into the renal vein. In the remaining 66 patients, renal vein invasion was associated with other adverse prognostic factors. Life expectancy was lower for patients with other concurrent adverse prognostic factors than for those affected by renal vein involvement alone (p < 0.0001). In the latter group, survival expectancy was similar to those with stage T2N0M0 tumor. In 7 cases (29%), inferior vena caval invasion was not associated with other adverse prognostic factors. In the remaining 15 patients (71%), vena caval involvement was associated with other adverse prognostic factors. Concurrence of other adverse prognostic factors with vena caval invasion significantly decreased the disease-specific survival expectancy in comparison with the patients in whom vena caval involvement was the main prognostic factor (p = 0.008). In these patients, disease-specific survival was similar to those with stage T2N0M0 tumor., Conclusion: Renal vein or inferior subdiaphragmatic vena caval involvement does not significantly affect prognosis in patients with RCC., (Copyright 2001 S.

Objective: To report an extremely rare clinical pathological observation of a case of primary lymphoma of the epididymis, without testicular or systemic involvement, and to update the relevant literature., Materials and Methods: A 25-year-old white male patient complaining of right scrotal pain was referred to our department. Clinical examination detected a hard painful mass at the right epididymal head. Epididymitis was diagnosed and conservative therapy with antibiotics and anti-inflammatory drugs was given. After 2 months of therapy the patient was admitted to our department because a tumor was suspected. Tumor markers were normal. Right scrotal exploration was performed through a standard inguinal incision. The epididymal head was completely replaced by a hard white mass. Fresh frozen sections indicated a malignant tumor. Right radical orchiectomy was performed., Results: High-grade primary epididymal non-Hodgkin's lymphoma with diffuse large cells (group G according to the Working Formulation) was diagnosed. Clinical pathological staging detected stage IE (extranodal) primary epididymal lymphoma. The patient was referred to the Hematologic Unit for combined chemotherapy, according to the VACOP-B protocol. After an 18-month follow-up the patient is well and disease free., Conclusions: When an epididymal mass does not benefit from medical treatment, scrotal exploration and fresh frozen sections of the lesion should be done. The possible bilateral involvement by primary epididymal lymphoma has to be kept in mind. Radical orchiectomy is the treatment of choice for primary lymphoma of the epididymis. Adjuvant chemotherapy is indicated in high-grade malignant lymphoma. Prognostic parameters of the disease may be the grade of malignancy and the size of the tumor., (Copyright 2001 S.

Objectives: To discuss the modern imaging techniques and preoperative management of pheochromocytoma and to report on one additional case., Methods: A 66-year-old male with an incidentally discovered left adrenal mass is described. The adrenal medulla strongly accumulate 131 I-metaiodobenzylguanidine (MIBG). The patient underwent left adrenalectomy after preoperative therapy with alpha and beta-blockers. The recent literature on pheochromocytoma modern imaging techniques and preoperative management is reviewed., Results: MIBG scintigraphy diagnosed a benign functioning adrenal pheochromocytoma, allowing preoperative medical management. Postoperative workup was unremarkable. Diagnosis of pheochromocytoma was confirmed by immunohistopathology. At 18 months follow-up, the patient is alive and disease-free., Conclusions: Incidentally discovered adrenal masses have to be investigated to detect malignancy and subtle hormonal overproduction. MIBG scintigraphy has a high specificity (100%) in detecting pheochromocytoma, metastasis, surgical residual tumor, local relapse and other adrenal crest tumors. Positive results of octreotide scintigraphy in detecting malignant pheochromocytoma have been reported. Currently, pheochromocytoma removal is a safe operation with mortality rates ranging from 0 to less than 3%. Preoperative alpha adrenergic blockage with phenoxybenzamine or prazosin is important in decreasing the operative risk. Beta-blockers may be necessary for cardiac arrhythmia. Intraoperative invasive monitoring of hemodynamic variables may be both diagnostic and therapeutic of inadequate preoperative management. Lifelong follow-up for patients with pheochromocytoma is important.

Objective: To report our 20-year experience with nephron-sparing surgery in the treatment of Fraley's syndrome., Materials and Methods: From September 1976 to July 1996, 6 women, 18-43 years old, underwent surgical treatment. All patients had been suffering debilitating right flank pain for at least 6 months before the operation. Diagnosis was in call cases made with the use of intravenous pyelography and renal arteriography, which showed a vascular impression on the superior infundibulum with secondary dilatation of the upper pole calyx. This was localized only on the right side in 5 cases, while in 1 it was bilateral though more severe on the right. Ipsilateral nephroptosis was observed in 2 of the patients. In 2 cases in whom the superior infundibulum was sufficiently long, an infundibulo-infundibulostomy with everted flaps was performed. In a case in whom a short infundibulum was compressed between a venous and an arterial branch, Fraley's infundibulopyelostomy was carried out. In 1 patient in whom the infundibulum was compressed by the anterior-superior segmental artery, a Heineke-Mikulicz-type infundibulorrhaphy was combined to vasopexy. In the remaining 2 cases, the infundibulum was not cut: in one case, a simple vasopexy of two vascular branches was carried out, while in the other, a minor arterial branch was ligated and divided. In 4 patients, nephropexy was also performed., Results: No significant intra- or postoperative complications were observed. Follow-up averaged 102.5 months. Pain relief was complete in 5 cases, in whom disappearance of the vascular impression was also radiologically demonstrated. Only 1 patient, who underwent infundibulorrhaphy and vasopexy, experienced occasional flank pain and urinary infection after the operation, with just a slight improvement in the excretory urogram., Conclusions: Surgical treatment of Fraley's syndrome is indicated only in symptomatic and/or complicated cases; in relation to the type of obstruction and the anatomy of the intrarenal structures, whether excretory or vascular, several effective nephron-sparing techniques can be selected.

To discuss retroperitoneal fibrosis (RPF) etiopathogenesis and to report on our experience in the treatment of the disease. From 1977 to 1998 26 RPF patients, 15 idiopathic (I group) and 11 secondary (II group), entered our clinic. Vascular risk factors of the I group were cigarette smoking (73.3%) and arterial hypertension (46.6%). Etiologic factors of the II group were aorta abdominal aneurysm (four cases), radiation therapy for female genital tract cancer (four case), aorto-bifemoral bypass for aorta aneurysm (two cases), retroperitoneal non-Hodgkin lymphoma (one case). Treatment performed for idiopathic disease was medical in eight cases (alone in two, with endourologic measures in six) using corticosteroids in five and tamoxifen in three; only endourological in three and surgical in four (nephrectomy in two patients, ureterolysis and ureteroneocystostomy in one, pyeloureterolysis in one) with perioperative corticosteroid treatment in three cases. Treatments performed in patients with secondary disease were endourologic in five surgical in three (ureteroureterostomy, ureteroneocystostomy, pyeloureterolysis and pyeloreduction), medical with corticosteroids in two; one patient affected by perianeurysmatic fibrosis did not require any treatment because of disease's spontaneous recovery. Medical treatment induced symptom remission and plaque reduction in all patients. Surgery determined complete recovery in all patients except for one in whom the disease relapsed with controlateral urinary tract involvement. Medical RPF treatment for idiopathic or secondary disease is effective in the first stage. Disease management with tamoxifen is easy to perform, safe and effective. In the steady state of RPF the best results are obtained by surgery and perioperative glucocorticoid therapy reduced significantly fibrosis' relapse.

Objective: To evaluate the general state of health and the psychological well-being in a group of 155 patients after surgery for urological malignant neoplasms., Materials and Methods: Surgery was performed in 55 patients for renal cell carcinoma, in 54 for invasive bladder carcinoma, in 30 for adenocarcinoma of the prostate, and in 16 for squamous penile carcinoma. All patients were invited to self-compile the General Health Questionnaire (GHQ) - 12 items according to Goldberg and the Hospital Anxiety and Depression Scale. Results were compared with those in a group of patients who underwent retropubic prostatectomy for benign prostatic hyperplasia., Results and Conclusion: The general state of health was significantly more impaired in neoplastic patients than in the control group. Levels of anxiety were significantly higher but depression levels were similar in both groups. As far as the type of tumor is concerned, patients who underwent radical cystectomy for bladder carcinoma and those treated with partial penectomy for squamous penile carcinoma showed a significant impairment of the general state of health compared with controls. Higher levels of anxiety were observed in patients who underwent ileal conduit after radical cystectomy, in those treated with radical prostatectomy for prostate cancer and in those who underwent partial penectomy. Significantly higher levels of depression than in the control group were observed only in patients with ileal conduit., (Copyright 2000 S. Karger AG, Basel)

Objective: The purpose of our work is to examine how partially or totally radical surgery and radiotherapy can weigh on quality of life in patients with squamous carcinoma of the penis, considering whether quality of life can be a good criterion in treatment options., Material and Methods: We have interviewed 17 patients alive and disease-free (average follow-up 69.43 months) after surgical treatment or radiotherapy for cancer of the penis (emasculation, 2; total amputation of the penis, 2; partial penectomy, 11; radiotherapy, 2). Tests used: General Health Questionnaire (G.H.Q.-12 by D. Goldberg); Hospital Anxiety and Depression Scale (H.A.D.S.); Social Problem Questionnaire (S.P.Q.); Overall Sexual Functioning Questionnaire (O.S.F.Q); Family APGAR Questionnaire (F.A.Q.); Performance Status ECOG., Results: Thirty-five per cent of the patients presented limitations in their state of health and social problems. Anxiety was evident in 29.5% of the patients and depression in 6%. The global sexual function was compromised in 76.5%., Conclusion: The profile of quality of life resulted compromised in the patients who had undergone radical surgical treatment. The sexual function was the most altered component. The impact of the pathology and its treatment on the other domains of quality of life proved less significant.

Antegrade ejaculation requires intact anatomy and innervation of the bladder neck. Retrograde ejaculation is an uncommon cause of infertility and can be defined as the escape of seminal fluid from the posterior urethra into the bladder. This pathological condition can result from disturbances at the bladder neck due to anatomical lesions, neuropathic disorders or pharmacological influences. Also congenital and idiophatic causes have been described. The diagnosis may be confirmed by findings sperm in post-coital specimens of urine. Pharmacological manipulation, electro-ejaculation and vibro-ejaculation can be utilized to recovery ejaculation. When anterograde ejaculation in this patients cannot be restored artificial insemination using sperm recovered from the antegrade post-coital urine is indicated. The aim of this paper is to evaluate the data of literature on aetiology and therapy of retrograde ejaculation.

The authors describe a case of gunshot wound of the male genitalia by two low-velocity bullets. The first bullet caused a lesion of the right testicle and came out of the right hemiscrotum; the second one had penetrated the left gluteal region with no exit wound. The penile ultrasound confirmed the presence of the bullet at the root of the right corpus cavernosum. The patient underwent exploratory surgery, drainage of the voluminous bilateral scrotal hematoma, and suture of a laceration of the right-testicle cranial portion. Due to the absence of active bleeding, voluminous hematoma and serious injuries in the corpus cavernosum, no surgical removal of the bullet in the right corpus cavernosum was required. The patient regained a normal sexual function 1 month after the operation.

Objective: The purpose of this work is to evaluate our experience with the surgical treatment of penile squamous carcinoma, analyzing the therapeutic results in terms of local recurrence rates, survival and mortality rates., Material and Methods: From 1976 to 1997, 47 patients were treated at our institution for carcinoma of penis. Treatment of primary tumor was conservative in 8 patients (17%). Partial penectomy was performed in 30 patients (63.8%); total penectomy in 5 (10.7%) and emasculation in 4 (8.5%). Pathological stage was pTis in 2 cases (4.2%), pT1 in 20 (42.6%), pT2 in 21 (44. 7%) and pT3 in 4 (8.5%). The tumor was clinically overstaged in 13 patients (27.7%) and understaged in 4 (8.5%). Bilateral inguinal lymphadenectomy was performed only in 4 patients clinically N+ (pN2) and in 3 clinically N0 (pN0)., Results: Local recurrence rate was 43% in the patients with pT1 stage tumor treated conservatively. No local recurrence was observed after penectomy. 19 patients (40.4%) are alive and disease-free; 17 patients (36.2%) died of the tumor and 11 patients (23.4%) died of other causes but disease-free. Mean follow-up is 69.43 months. The overall 5-year survival rate was 34%., Conclusion: Partial penectomy gives better results than conservative treatment in the local management of the T1 stage tumor. Survival and mortality rates are related to both pathological and histological stages. The high mortality rate observed in the pT2 stage tumors in our experience might be related to the fact that in this stage an inguinal lymphadenectomy was not performed as a rule., (Copyright 1999 S. Karger AG, Basel.)

Surgical treatment of the megaureter in adults is only indicated when important symptoms and/or complications occur. The Authors report their experience with eight adult patients affected by megaureter, undergone to conservative surgery. The average age of the patients was 36 years (range 21-52). The disease was unilateral in five cases (four on the right side and one on the left), bilateral in three. In five patients megaureter was primary (obstructed in four, refluxing in one). A case of megaureter with ectopic orifice in the prostatic urethra was observed. The remaining two cases, already operated in other hospitals, were a segmentary megaureter associated with vesico-ureteral reflux secondary to endoscopic incision of an ureterocele and a bilateral refluxing megaureter in a patient undergone to bilateral ureterocystoneostomy because of primary megaureter in his childhood. All patients underwent ureterocystoneostomy, performed with Politano-Leadbetter antireflux technique in six cases and with direct non-antireflux technique in two. A reductive Hendren ureteroplasty was also performed in 7 cases. The average length of follow-up is actually of 82 months (range 5-231). Satisfactory results were obtained in three primary obstructed megaureters, in the megaureter with ectopic orifice and in the segmentary megaureter associated with reflux. In two patients with refluxing megaureter surgery was unsuccessful and a new operation was necessary. Finally, one patient with primary obstructed megaureter underwent endoscopic dilatation of the strictured vesico-ureteral anastomosis two months after the ureterocystoneostomy.

The treatment of impotence due to venous leakage is remedied by creating an increase in the resistance of the venous outflow in order to trap arterial blood within the corpora cavernosa of the penis during erection. The percentage of success reported in Literature after resection of the deep dorsal vein and ligature of the cavernous veins varies from a minimum of 12.5% to a maximum of 75%. Interventional radiology represents a valid alternative to traditional surgery in the non-prosthesis treatment of erectile dysfunction of venous origin due to the absence of complications and lack of intrusiveness and for the encouraging short and mid term results obtained. From May 1991 to February 1997, seventeen patients (aged between 24-54, average age 36 years) affected by venous leakage underwent embolisation of the principal veins of drainage of the corpora cavernosa. All patients were previously strictly selected in order to exclude those affected by arterial, neurological, endocrine or ++psychological disease. Pathologic venous drainage was shown by pharmacocavernosometry and pharmacocavernosography. The technique employed consisted in isolation and catheterization of the deep dorsal vein of the penis with a cannula needle of 14 G and subsequent ligature and simple section of the vein; venous leakage fluoroscopic evaluation; coils placement under radiological control, in the distal tract of each vein chosen to be occluded; and then at last, embolization of the deep dorsal vein. A fluoroscopic control performed after these procedures showed the correct vascular occlusion. The operation has an average duration of 120 minutes and requires two-day hospitalisation. In 12% (2/17) of the selected cases a technical failure was recorded due to difficult catheterization of the periprostatic plexus, therefore only surgical ligature and section was carried out in the penile deep dorsal vein. Only in one case (6%) there was a slight and transitory oedema of the penis observed. The average follow-up is 34 months (range 3-72 months). Up to now, 11 patients over 15 (73.4%) refer a good improvement of erectile dysfunction together with a satisfactory sexual activity. In two cases (13.3%) only partial improvement have been referred. Only 2 cases (13.3%) did not obtain any benefit from treatment.

Idiopathic varicocele can compromise the spermatogenetic function of the testicle and associate with alterations of the semen quality. The treatment of varicocele stops the progress of testicular damage and improves spermatogenesis and semen parameters. These are the main alternatives to the traditional surgical treatment of varicocele retrograde percutaneous occlusion of the internal spermatic vein using sclerosing agents and embolizing devices (either separately or in combination), microsurgical ligation via inguinal or sub-inguinal approach, laparoscopic ligation and, more recently, antegrade scrotal sclerotherapy. None of these techniques can be considered the "gold standard" therapy. Literature does not point out any significant difference between them, either considering the absence of reflux percentage, or the improvement of semen quality, or the pregnance rate. Therefore cost comparison may be a valid criterion in the choice of treatment for varicocele correction. The total cost of the surgical retroperitoneal unilateral ligation of the internal spermatic vein is 968,805 Lire, while for the bilateral ligation it is 1,118,285 Lire. The costs of sclerotherapy and percutaneous embolization are respectively of 698,750 Lire and 1,708,950 Lire. The combination of the two techniques amounts to 1,918,230 Lire. Laparoscopic bilateral ligation costs 2,437,935 Lire. Antegrade scrotal sclerotherapy costs 191,035 Lire if unilateral, 216,580 Lire if bilateral. After considering these data we can say that antegrade scrotal sclerotherapy is the first choice economically in the treatment of both unilateral and bilateral varicocele.

We report a case of eosinophilic cystitis the onset of which was characterized by acute peritonitis secondary to a spontaneous intraperitoneal rupture of the vesical cupula. The patient was treated with urgent partial cystectomy in another hospital and 3 months later he underwent endoscopic diathermic coagulation of a residual inflammatory lesion at our institution. After an 18 month endoscopic follow-up no further signs of recurrent eosinophilic cystitis have been pointed out. The non-traumatic bladder perforation and the absence of any other bladder pathology might indicate that eosinophilic cystitis can be responsible for complete bladder rupture.

Polyorchidism is a rare anomaly with approximately 70 cases reported in literature. The exact explanation for the production of polyorchidism is not known, although several theories have been proposed, including anomalous appropriation of cells, initial longitudinal duplication of the genital ridge and transverse division of the genital ridge, either through some local accident of development of peritoneal bands. A functional classification based upon the embryogenic development is provided. Type I: the supernumerary testis lacks an epididymis and vas. The split-off part of the primordial gonad does not communicate with the mesonephric tubules from which the epididymis develops. Type II: the supernumerary testis is linked to the regular testis by a common epididymis and shares a common vas with it. The division of the genital ridge occurs in the region where the primordial gonads are attached to the mesonephric ducts, although the latter are not divided (incomplete division). Type III: the supernumerary testis has its own epididymis but shares the vas with the regular testis. This variant results from a complete transverse division of the genital ridge. In the majority of the reported cases, the patients are asymptomatic and have painless groin or testicular masses. Approximately 50% occur as maldescent or cryptorchidism, and about 30% are associated with indirect hernia. The remaining 20% are discovered variously in relation to torsion, or are associated with hydrocele, epididymitis, varicocele or infertility. Moreover, since there is a 20 to 40 fold increase in testicular malignancy in patients with cryptorchidism compared with the normal testis, tumours of the supernumerary testicles are not unusual. We reported two cases of polyorchidism: the first patient is probably a longitudinal division of the genital ridge and the second is a completely duplication of the primordial gonads. The patients described vague, intermittent, testicular pain. Physical examination and the scrotal sonography and magnetic resonance revealed in the first patient a supernumerary testis in the right scrotal space and in the second a bilateral double testis. In conclusion we think that in the absence of any concomitant disorder and if testicular tumor can be ruled out by ultrasonography and magnetic resonance imaging, surgical exploration with biopsy is unnecessary.
