We stratified the cohort by treatments: Naive of treatment (Naive, n=67), Calcium and Vitamin D (CaVitD, n=87), Testosterone (Te, n=36), Alendronate (AL, n=88), Risedronate (Ri, n=39), Denosumab (Dmb, n=43) and Teriparatide (PTH, n=30).

Effects of testosterone treatment on body composition in males with testosterone deficiency syndrome.

Objective: We evaluated the safety of testosterone treatment and its efficacy on body composition in males with testosterone deficiency syndrome (TDS) over 24 months.

Methods: 50 males aged 50-65 years with TDS (Aging Males Symptoms Scale [AMS] > 26 and calculated free testosterone [cFT] 250 pmol/l) were administered 50 mg testosterone gel daily for one year. During the second year, patients received 1000 mg of testosterone undecanoate every 2-3 months.

Effects of testosterone treatment on bone mineral density in men with testosterone deficiency syndrome.

The decline in testosterone levels found in men with testosterone deficiency syndrome (TDS) is associated with a decrease in bone mineral density (BMD). To study the safety profile and efficacy of testosterone treatment on BMD in patients with TDS. In this 2-year prospective open-label study, patients were administered 50 mg of testosterone gel daily (adjustable after 3 months up to 75-100 mg or down to 25 mg) for 12 months, followed by treatment with 1000 mg of testosterone undecanoate every 2-3 months from months 12-24.

[Testosterone-deficiency as a risk factor for hip fracture in eldery men].

Objectives: Progressive loss of bone mineral density weakens the bones and increases the probability of osteoporotic fractures. It is well known that sex steroids play a role in the maintenance of bone density. This fact makes us think there might be a correlation between sex steroid levels and osteoporotic hip fractures.

[Intracavernosal methoxamine self-injection for the treatment of low-flow recurrent priapism].

We report the case of a young man with a recurrent idiopathic priapism, successfully treated with methoxamine intracarvenosal self-injections. The patient was instructed in intracorporeal self-injection of this pure alpha-1 adrenergic agonist, which provided complete detumescence. The patient became asymptomatic after one month of domiciliary treatment.

[Massive bladder hernia].

Objectives: We report a case of a huge bladder hernia conditioning the migration of almost all the bladder into the scrotum.

Methods And Results: 65-year-old male being studied for BPH who presents a scrotal tumor, which turned out to be a huge inguinal bladder hernia in scrotum, paraperitoneal, accompanied by an inguinal hernia. The treatment consisted in bladder resection and repair of the inguinal hernia with a marlex mesh.

[Incomplete urethral duplication].

Urethral duplicity is a rare congenital malformation. We report a case of one 25 years old male suffering recurrent urinary infections. The diagnostic of uncompleted urethral duplicity was performed by retrograde urethrography and micturating cystourethrogram.

[Our experience with the implant of single component integrated prostheses (Hydroflex-Dynaflex)].

Introduction And Objectives: To present our experience with Hydroflex and Dynaflex self-contained inflatable penile prosthesis.

Material And Methods: Between october 1988 and december 2000 a total of 63 men underwent implantation of 8 Hydroflex and 55 Dynaflex penile prosthesis. The follow-up period ranged from 12 and 127 months (mean 54.

[Treatment of urethral stenosis with thermo-expandable prosthesis "Memotherm". Our experience].

Objective: To report our experience in the treatment of recurrent urethral stricture in the male with the Memotherm heat-expansible stent.

Methods: From December 1995 to March 1999, the Memotherm heat-expansible stent was utilized in 4 patients with urethral stricture that had undergone urethrotomy procedures, periodic urethral dilatation and in those cases with post-traumatic stricture, open surgery for urethroplasty and urethral reattachment. All patients had multiple recurrences of the urethral stricture that was not amenable to the treatments utilized, therefore the intraurethral stent was inserted.

[Penile erectile dysfunction secondary to hypophyseal adenoma].

Increased production of prolactin by the pituitary is a factor to be taken into account as a cause of peneal erectile dysfunction (PED), which varies depending on the series from 1 to 16%. 1,2,7 We contribute in this paper one patient with infertility and erectile dysfunction secondary to a prolactin-producing pituitary tumour, prolactin plasma levels returning to normal after treatment with bromocriptine, which also achieved a remission of the clinical picture.

[Renal angioscopy].

Presentation as a novelty of the application of endoscopic methods in the display of the renal artery (angioscopy). Review of findings seen in the renal artery of a donor corpse with polytraumatism using direct view with a MiniScope-type rigid urethroscopy and the possible future application of this technique.

[Cyst of the prostatic utricle].

Presentation of a case of prostatic utriculus cyst which due to its size and the patient's history suggested a differential diagnosis with a urethral or vesical diverticulum. Awareness of frequent association to urethral malformations and azoospermia would be very useful when choosing a treatment strategy in such cases.

[Rigid ureteroscopy: results and complications].

We make an evaluation of 66 ureteroscopies (URS) carried out in our Service over a period of 18 months. In 55 cases it was done for therapeutic purposes in ureteral lithiasis, and in 11 cases it was for diagnostic purposes. In the treatment of lithiasis resolutive effectivity at the first attempt was 68%, in 9% ureterolithotomy had to be performed due to the impossibility of approaching the calculus, and in 23% supplementary treatment was carried out by means of external litrotripsy.

Leydig cell in idiopathic varicocele.

In a group of 31 patients with idiopathic varicocele (IV), testicular biopsy showed a decreased tubular diameter, hyperplasia in the number of Leydig's cells (LC; many with cytoplasmic vacuolization and atrophy) and a decrease in the number of positive LC in testicular tissue sections stained with the testosterone peroxidase-antiperoxidase method. Similar values were seen for the testis with IV and for the contralateral testis. All of this, in addition to the lack of significant differences in the volume of cytoplasmic organelles in the LC, leads us to think that both testes are equally involved.

[Fibrous polyp of the ureter].

We report on a 72-year-old male patient with fibrous ureteral polyp which had been diagnosed following the incidental finding of a ureteral filling defect on radiographic evaluation for prostatism and gross intermittent hematuria of several months. We underscore the low frequency of this disorder and the therapeutic implications of differential diagnosis to distinguish this condition from other causes of ureteral filling defects.

[Renal hydatid cyst].

We present a case of urinary way fistulized renal hydatid cyst, which displayed itself clinically by repeated nephritic colics caused by the expulsion of calcified daughter vesicles. We make special mention of the diagnostic process and the surgical technique used, which included cystopericystectomy and anterograde ureteroscopy for the extraction of the calcified daughter vesicles at ureteral level.

Salivary testosterone in cryptorchid pubertal boys: a parameter to assess the gonadal function.

The authors studied salivary and serum testosterone (T) levels in basal conditions and at 6 and 12 months after orchidopexy in 36 pubertal boys with unilateral or bilateral cryptorchidism. Boys were divided into two groups according to Tanner classification. Salivary and serum T levels were significantly lower in the group with scanty or absent sexual development than those obtained in the group with normal development.

[Urethral foreign body].

A case is described of a urethral foreign body of long evolution, introduced for masturbatory purposes and which had its clinical origins as a periurethral abscess. We comment on the diagnostic steps and the therapeutic attitude followed.

Postpubertal cryptorchism. Morphofunctional study with special reference to Leydig's cells.

In a group of 17 patients of postpubertal age with unilateral (n = 15) or bilateral (n = 2) cryptorchism, a significant decrease in the tubular diameter was observed, in addition to Leydig cell hyperplasia (many with cytoplasm vacuolization and/or atrophy) in both the cryptorchid testes and in the contralateral scrotal testes. The number of testosterone-positive Leydig cells in testicular tissue sections, studied with peroxidase-antiperoxidase, was diminished in the cryptorchid testes, whereas in the contralateral scrotal testes it was similar to the control group. Together with normal testosterone levels and elevated luteinizing hormone and follicle-stimulating hormone levels in peripheral blood, this leads us to think of a compensated dysfunction of the Leydig cells.
