Testicular sperm retrieval method: histological effects of location of incision.

This research was conducted to evaluate the effects of a transverse vs. longitudinal incision for testicular sperm retrieval. Rats were divided into 4 groups: I: control, II: sham operation, III: longitudinal incision TSRM, IV: transverse incision TSRM. Group II (sham operation) had a dissection of left testis/spermatic cord, then closure of wound. Group III underwent dissection of left testis, then a "longitudinal" incision (15 mm long) of testis, which was fully opened then closed again and sutured with 5-0 Vicryl sutures. Group IV underwent dissection of the left testis, opening of the testis with a "transverse" incision, then closure with 5-0 Vicryl. The seminiferous tubule diameter was 0.118-0.224 mm in all groups. Inflammation and abscess formation occurred in one testis each in the sham and longitudinal incision groups, and in two testes in the transverse incision group. There were no differences in histopathology or scoring between the longitudinal and the transverse incision.

Is it necessary to use sexual health inventory for men (SHIM) routinely?

This study was conducted to evaluate the prevalence of erectile dysfunction (ED) according to the Sexual Health Inventory for Men (SHIM) and its relationship with age and education. Six hundred and thirty-nine male patients aged > or = 20 years attending a urology clinic were studied. After a detailed history and physical examination, all patients were evaluated with SHIM. Scores were categorized into 5 groups: severe (1-7), moderate (8-11), mild-moderate (12-16), mild (17-21) and normal (22-25). The patients were classified into three groups according to their application to the urology clinic: A--patients attending specifically for ED; B--patients not ED based on SHIM and attending not for ED; C--patients ED based on SHIM, but attending not for ED. In addition, patients were partitioned into 3 age groups according to their age: 20-35, 35-55 and >55 years. Educational levels were of 2 groups: lower education and higher education. Erectile dysfunction was determined in 3.7% in the 20-35 years group, 55% in 35-55 years and 41% in >55 years (P < 0.01). In men having ED through SHIM and attending not for ED, the ratio of ED was higher in the lower education than in the higher education groups (p = 0.01). SHIM is a diagnostic tool used for ED, and routine application of SHIM for patients attending the urology clinic is advisable.

Does asymptomatic inflammation increase PSA? A histopathological study comparing benign and malignant tissue biopsy specimens.

AIM: To determine the effect of inflammation on postage-specific antigen (PSA) levels in patients who were performed transrectal ultrasonography (TRUSG) guided prostate biopsy because of high PSA levels. MATERIALS AND METHOD: 376 tissue specimens of 47 patients with BPH and 176 tissue specimens of 22 patients with prostate adenocancer were analysed histopathologically. Digital rectal examination, TRUSG, and PSA measurements were performed to all the patients before biopsy. Sextant biopsy was performed. Two pathologists examined all the biopsy specimens in blinded fashion. Inflammation pattern was categorized as glandular, periglandular, stromal and perivascular and intensity of inflammation graded from 1 to 3. RESULTS: The mean age of the patients was 66.2 years. The mean serum PSA level of the initial biopsy was 8.7 ng/ml in the BPH and 13.4 ng/ml in the prostate Ca. No relation was found between the serum total PSA levels and prostate volume or patient's age in BPH patients (P = 0.258). In BPH patients stromal, periglandular, glandular inflammations did not increase PSA levels. Perivascular inflammation increased PSA levels significantly. CONCLUSION: The inflammation in perivascular field increases serum PSA levels (P = 0.007). Although high serum PSA levels shows correlation with cancer in biopsy, there is no such significant relation with rebiopsy results and PSA levels at last studies. Because of this, these patients' biopsy samples must be reinspected for infection findings and atipic biopsy or high grade PIN. The result of our study showed that histological perivascular infection within the prostatic gland is a significant factor to serum PSA levels in BPH. If you have negative biopsy sample, pathology must indicate the place of the infection. Follow up of this patient and rebiopsy time are decided according to the result of this negative biopsy sample.

Prevalence of nocturnal enuresis and accompanying factors in children aged 7-11 years in Turkey.

There has been limited epidemiological research about nocturnal enuresis in Turkey. The objectives of this study were to ascertain the prevalence of nocturnal enuresis and the epidemiological factors associated with this in Turkish children aged 7-11 y, living in Manisa. Included in the study were 2000 children from various primary schools in Manisa. Parents were asked to fill out our specially designed questionnaire. In all, questionnaires for 1703 children were completed and returned to the department (871F, 51.1%; 832M, 48.9%). The prevalence of nocturnal enuresis for females was 10.6%, for males it was 16.9% and the overall prevalence was 13.7%. The prevalence of nocturnal enuresis decreased with age. Enuresis nocturna was found to be more common in children with a family history of bedwetting (76.5%). Deep sleeping, poor toilet habits and low educational level of the family were associated with enuresis. Consanguineous marriage did not influence the incidence of enuresis nocturna. There was no difference between enuretics and nonenuretics with reference to breastfeeding, being firstborn or being right- or left-handed. In our opinion, enuresis is an important problem for both families and children in Turkey for which specific guidelines should be developed. Various methods have been tried in the treatment of enuresis because of its multi-factorial aetiology. Child, family and physician co-operating together achieve the best help to both child and family.

The effects of extensive vas mobilization on testicular histology during orchiopexy.

We were aware that extensive mobilization of vas deferens during orchiopexy could cause secondary infertility due to testicular damage and/or functional obstruction of the vas deferens. We decided to perform this experimental study in order to document the effects of this procedure on the testis. Thirty adult fertility-proven New Zealand white rabbits were randomly divided into 3 groups. Ten rabbits underwent extensive mobilization of the vas deferens and the other 10 rabbits had vasectomy on the left side. The remaining 10 rabbits were explored on the left side only and were considered sham controls. Four weeks later all rabbits underwent bilateral orchiectomy. Mean seminiferous tubular diameters and Johnsen's testicular biopsy scores were noted. Comparison of the three groups showed that vas mobilization and vasectomies cause no effect on the viability of testis, however, significant testicular histological changes, which were different from the controls and contralateral testis, were observed. We concluded that during any surgical intervention involving the inguinal canal, vascular and neural supports of the vas deferens should be preserved as much as possible in order to avoid iatrogenic damages to the testis.

Effect of long-term alcohol abuse on male sexual function and serum gonadal hormone levels.

PURPOSE: The relationship between chronic alcohol abuse and male sexual dysfunction and pituitary gonadal function abnormalities remains uncertain. The purpose of this study was to assess the effect of chronic alcoholism on sexual functions and serum hormone levels. MATERIALS AND METHODS: Forty-five chronically alcoholic men and a control group of thirty healthy non-alcoholic volunteers were enrolled in the study. Each of the men in the study and control group were interviewed according to a sexual dysfunction questionnaire by an urologist. Blood samples were collected for evaluation of hormone levels. Sera were stored at -70 degrees C for analysis. RESULTS: The sexual desire and erection scores of alcoholic men were not statistically different from those of the control group. Fourteen out of the 45 alcoholic men complained of loss of erection during sexual activity. No significant difference in hormone levels between groups was found except for FSH. CONCLUSION: In the absence of hepatic and gonadal failure in chronically alcoholic men, there is no significant difference in serum hormonal levels, sexual dysfunction form, and sexual functions between alcoholics and normal healthy non-alcoholic men.

Effects of extracorporeal shockwave lithotripsy at different stages of pregnancy in the rabbit.

Although SWL is now the most common treatment modality for urinary tract stone disease, it is not regarded as a safe method for pregnant patients because of its potential harmful effects on fetus. Using a rabbit model, we investigated whether SWL might cause fetal injury when administered at various developmental stages. Two groups of pregnant rabbits were given 1000 shockwaves either early or late in the gestational period. Time-matched controls did not receive shockwaves. After spontaneous labor, all newborn rabbits were counted, weighted, and measured, and specimens were taken from organs and examined histopathologically. The numbers, weights, and diameters of the newborns in each group were similar. There was no notable histopathologic finding in the heart and brain specimens of any of the newborns, whereas noticeable congestion and multiple focal intraparanchymal microhemorrhages were found in lungs, livers, and kidneys of the animals that had been exposed to shockwaves early in gestation. In conclusion, this study shows that SWL is not a safe treatment in early pregnancy.

The effect of testicular torsion on the contralateral testis and the value of various types of treatment.

In an attempt to investigate the effect of testicular torsion and various forms of treatment on the contralateral testis, an experimental study on rats was undertaken. The first group comprised control animals. In the second group the left testes were twisted 720 degrees and the right testes were removed 4 weeks later for histopathological examination. In the third group the rats were subjected to a left detorsion procedure 24 h after torsion, while in the fourth group cortisone treatment was added to the above procedure. The fifth group consisted of rats which had undergone left orchiectomy 24 h after torsion and the sixth group had cortisone treatment plus orchiectomy after torsion. Cortisone treatment was started 24 h after testicular torsion and continued for 4 weeks. Histopathological examination of the contralateral testes which were removed 4 weeks later showed that either orchiectomy plus cortisone or detorsion plus cortisone was more successful than other forms of treatment.
