Abstract
BACKGROUND Telerehabilitation is an approach that is growing in importance and rapidly becoming more prevalent. However, the potential barriers to this approach and its effectiveness relative to face-to-face treatment still need to be determined. PURPOSE The aim of this study was to investigate the technology and access barriers, implementation and organizational challenges, and communication barriers faced by patients undergoing postoperative telerehabilitation after hand tendon repair surgery. It also aimed to investigate the effect of telerehabilitation on pain, kinesiophobia, and functional outcomes. STUDY DESIGN Prospective, open-label, nonrandomized comparative clinical study. METHODS The study was conducted with 44 patients who underwent tendon repair surgery due to tendon injuries of the extrinsic muscles of the hand. Participants were divided into two groups (face-to-face group and telerehabilitation group). All participants received three physiotherapy sessions per week for 8 weeks from their surgery (via video conference using mobile phones to the telerehabilitation group). An early passive motion protocol was applied for flexor tendon and zone 5-7 extensor tendon repairs. Mallet finger rehabilitation was performed for zone 2 extensor tendon repairs, while an early active short arc approach was used for zone 3-4 repairs. The telerehabilitation and face-to-face groups received the same treatment protocols three times a week. In the eighth week of treatment (in the 24th session), the Turkish version of the Arm, Shoulder, and Hand Injury Questionnaire (DASH-T) and Tampa Scale for Kinesiophobia were administered to all patients. The telerehabilitation group also underwent a barrier questionnaire. A pretreatment assessment could not be conducted. The independent-sample t-test was used for DASH-T data, and the Mann-Whitney U-test was used for Tampa Scale for Kinesiophobia to compare groups. RESULTS In the study, there were 24 participants (age: 31.58 ± 12.02 years) in the face-to-face group and 20 participants (age: 39.25 ± 12.72 years) in the telerehabilitation group. The two groups were similar in terms of DASH-T and pain (p = 0.103, effect size = 0.647, and p = 0.086, effect size = 0.652, respectively) in the 8 weeks. However, the telerehabilitation group had a higher fear of movement (p = 0.017, effect size = 3.265). The most common barriers to telerehabilitation practices were the fear of damaging the tendon repair and the need for help during the treatment. CONCLUSIONS We determined that face-to-face treatment in acute physiotherapy for patients who have undergone tendon repair may be more effective compared to telerehabilitation, as it appears to be less likely to induce kinesiophobia. However, in situations where face-to-face treatment is not possible (such as lockdown), telerehabilitation can also be preferred after at least one in-person session to teach and perform exercises.

Abstract
Introduction: Manual lymphatic drainage (MLD), one of the components of complex decongestive physiotherapy, which is accepted as the gold standard in the treatment of lymphedema, is used for therapeutic purposes in many diseases. The most well-known feature of MLD is that it helps to reduce edema. In addition to reducing edema, MLD has many effects, such as increasing venous flow, reducing fatigue, and raising the pain threshold. To the best of our knowledge, there is no study examining the effects of MLD other than its effects on edema in detail. The aim of this study is to compile effects of MLD and to provide a better understanding of the effects of MLD. Methods: A literature search was conducted in Medline, Embase, and the Cochrane Library in July 2019, to identify different effects of MLD. The articles were chosen by, first, reading the abstract and subsequently data were analyzed by reading the entire text through full-text resources. To undertake the study, we have collected information published about different effects of MLD over the last 30 years (1989-2019). According to our results, 20 studies met inclusion criteria. Conclusions: This study suggests that MLD can be used in symptomatic treatment of various diseases (multiple sclerosis, Parkinson's disease) considering the effects of MLD on the systems.

Abstract
This study was conducted to localize the testicular regions, which have better blood circulation by power Doppler ultrasonography in patients with nonobstructive azoospermia before testicular sperm extraction (TESE), and to investigate whether these vascularized areas have a high sperm retrieval rate or not. We evaluated 110 testes of 55 cases that were diagnosed as nonobstructive azoospermia. The mean age of the study group was 33 years (range 26 to 42). Patients with Y chromosome microdeletions, karyotype and hormonal abnormalities (except elevated FSH levels) were excluded from the study. In all cases, testes were evaluated by power Doppler ultrasonography before testicular sperm extraction. Testis was divided vertically into five equal parts and the area with maximum vascularity was determined subjectively. During testicular sperm extraction, starting from best-perfused areas, biopsies were done. If no motile or sufficient amount of sperm was found, TESE procedure was tried on the contralateral testis. TESE were performed from 82 testes and for the regions that show good and poor vascularity. The sperm finding rate was 38% and 14%, respectively (OR = 3.55)(p = 0.001). Power Doppler ultrasound mapping of the testis in nonobstructive azoospermic cases is a reliable and informative method to assess spermatogenic foci. It is a noninvasive technique that minimizes the unnecessary removal of hormone producing tissue and gives chance to end the TESE earlier than currently practiced procedures.

Abstract
Stress and Urge urinary incontinence may develop after a pelvic trauma especially after pelvic bone fractures. Incontinence may persist even though any type of bladder neck suspension is performed if malunion occurs between fracture ends. In stress and urge urinary incontinence developed after pelvic trauma, patients should also be evaluated for malunion of fractures which may lead to bone spurs and during any type of bladder neck suspension these should also be removed.

Abstract
OBJECTIVES To determine the effect of variations in pelvicalyceal volume on the results of extracorporeal shock wave lithotripsy (ESWL) and the relationship of stone load to estimated pelvicalyceal volume in patients with renal pelvic stones. PATIENTS AND METHODS In all, 204 patients with renal pelvic stones were treated primarily by ESWL. Exclusion criteria were radiolucent stones, dilatation of the renal collecting system, JJ stent insertion before ESWL and an inadequate follow-up. The surface area of the stones and the renal collecting system were measured using a grid of 1 mm2 divisions. The pelvicalyceal volume was calculated as 0.6 (area)1.27. To evaluate the treatment results a pelvicalyceal stone load (PSL) index, describing the relationship of stone load to total estimated pelvicalyceal volume, was defined as stone volume/renal collecting system volume. RESULTS The mean (range) pelvicalyceal volume of the patients was 13.24 (4.12-28.47) mm3 and the mean PSL index was 26.2%. The cumulative success rates according to the PSL decreased from 97% to 90% with increasing PSL, but remained at > 95% in patients with a PSL index of < 50%. In all, 184 sessions were applied and the session/patient ratio increased from 1.41 to 3.0 with increasing PSL. Complications were acute pyelonephritis in three and steinstrasse in five patients. CONCLUSION The PSL index appears to be a more accurate and reproducible method for predicting the outcome of ESWL, and has the advantage of considering the effect of pelvicalyceal anatomy.

Abstract
PURPOSE To compare the treatment options for lower ureteral stones larger than 1 cm. METHODS The records of 449 patients with lower ureteral calculi larger than 1 cm were reviewed retrospectively. Of these patients 342 (76.1%) were treated with extracorporeal shock wave lithotripsy (ESWL) (group 1), 66 (14.7%) with pneumatic lithotripsy (PL) (group 2) and 128 (28.5%) with ureterolithotomy (group 3). Eighty-seven (19.5%) patients underwent any of the two treatment modalities because of unsuccessful primary treatment. RESULTS The overall stone-free rates were 32.4, 90.9 and 95.3% for ESWL, PL and ureterolithotomy, respectively. These values were 84.4% for primary PL and 96.7% for primary ureterolithotomy. The re-treatment rate (46.4%) and secondary procedures were much more frequent in the ESWL group. There was no difference in the complication rates of the three groups. CONCLUSIONS Pneumatic lithotripsy with ureteroscopy seems to be an appropriate treatment for larger ureteral stones. While ESWL can be tried as a first treatment option because of its noninvasive nature, lower success and higher re-treatment rates limit its usefulness. Ureterolithotomy is still a reasonable alternative for these large or unfragmented stones.

Abstract
We investigated the efficacy of prophylactic use of single dose oral ofloxacin and trimethoprim-sulfamethoxazole regimens for transrectal prostate biopsy in 110 men. In the ofloxacin, trimethoprim-sulfamethoxazole and control groups, urinary infection was found in 2 (4.76%), 3 (6.66%) and 6 (26.08%) patients, respectively. Both of these antibiotic regimens produced a statistically significant reduction in urinary infection (p<0.02, p<0.05). Our study indicates that single dose fluoroquinolone or trimethoprim-sulfamethoxazole prophylaxis seems to be effective, practical and economical.

Abstract
OBJECTIVE To evaluate the immunologic etiology in unilateral testicular torsion, an experimental study in rats was carried out. MATERIALS AND METHODS 75 adult Wistar rats included in the study program were divided into six different groups according to a torsion-detorsion procedure. Torsion degree was kept constant for all animals (720 degrees ). Anti-rat immunoglobulin G (IgG) antibodies against spermatozoa antigens were identified in contralateral testicular tissue after 1 month following detorsion and/or orchiectomy of the twisted testicle. RESULTS We revealed antibody formation in animals subjected to unilateral torsion for 12 and 24 h, which then followed by detorsion of the testicle. IgG was identified especially on basal membrane of the tubules. CONCLUSIONS As the controversy on the exact mechanism of testicular damage in unilateral torsion still continues, our findings showed that a possible immunological etiology may play an important role in this respect.

Abstract
Leukocyte influx into the cortex and medulla of the kidney is seen following acute ureteral obstruction. To investigate the macrophage influx and alterations in glomerular filtration rate (GFR) and to evaluate the effects of early radiation therapy on these parameters, we evaluated 20 rabbits in four groups. In the first group preoperative technetium-99m scanning preceding bilateral ureteral complete obstruction was performed. All rabbits received whole body irradiation of 1316 rads. Then the bilateral ureteral obstruction was released after 24 hours. Two hours after releasing, the last scanning was performed. The kidneys were immediately removed and histopathological examination was done. In the second group, all procedures except radiotherapy were done. The third group underwent sham laparotomy to assess the effects of surgical trauma on renal functions. The fourth group of rabbits was considered as control. We have observed an apparent macrophage influx into the cortex and medulla of the kidney following bilateral ureteral obstruction (p=0.000). However, irradiation reduced the infiltration significantly (p=0.000). Also in cases who received radiotherapy GFR was preserved to a significantly higher degree (p=0.000). We concluded that irradiation following acute ureteral obstruction has protective effects on renal function through abolition of the infiltrating cells.

Abstract
OBJECTIVE To assess sensitivity, specificity, accuracy, positive predictive value and negative predictive value of nuclear matrix protein 22 (NMP22) test, BTA stat test and cytology in the urine of patients with a spectrum of urologic conditions, including bladder cancer. METHODS A total of 140 patients (40 with bladder cancer) provided a urine sample which was divided into appropriate aliquots for each of the tests cited above. The endoscopist, pathologist, cytologist and the person performing BTA stat test and NMP22 test were blinded as to the results of the other tests. RESULTS Receiver-operating characteristics curve interpretation determined that 12.0 U/ml was an optimal reference value for NMP22 to detect transitional cell carcinoma of the bladder in this patient group. Comparative results demonstrate a clear superiority of NMP22 and BTA stat tests in sensitivity in bladder cancer detection (p < 0.01), while cytology and NMP22 were better than BTA stat test in specificity (p < 0.05). CONCLUSIONS NMP22 and BTA stat test results represented significant improvement over urinary cytology for detection of transitional cell carcinoma. The sensitivities of NMP22 and BTA stat tests for detection of transitional cell carcinoma in this group of patients were as much as twice that of cytology. When the cutoff value of urinary NMP22 was set at 12.0 U/ml, NMP22 was more accurate than the other tests (p < 0.05).

Abstract
BACKGROUND AND OBJECTIVE Extracorporeal shockwave lithotripsy (SWL) is accepted as first-line therapy for kidney stones. The aim of this study was to evaluate SWL therapy in patients with congenital urinary system anomalies. PATIENTS AND METHODS A total of 120 patients with congenital urinary system anomalies and kidney stones who underwent SWL treatment were evaluated. Of these patients, 44 (37%) had horseshoe kidneys, 22 (18%) had rotation anomalies, 13 (11%) had pelvic kidneys, and 41 (34%) had ureteral duplications. The mean stone size was 2.09+/-0.71 (range 0.8-4.6) cm2, and a total of 232 sessions (1.93 sessions/patient) were applied. RESULTS The overall stone-free rate after completion of the SWL treatments was 70% (84 patients). In horse shoe kidneys the stone-free rate was 68%, and sufficient fragmentation was achieved in another 21%. These values were 59% and 32%, respectively, for malrotated kidneys, 54% and 39% for pelvic kidneys, and 83% and 12% for ureteral duplications. The 10 patients in whom SWL treatment remained unsuccessful had horse-shoe kidneys (five cases), malrotated kidneys (two cases), pelvic kidney (one case), and ureteral duplication (two cases). Open surgery was performed in eight patients with renal anomalies, and ureteroendoscopic lithotripsy was performed in two patients with ureteral duplication. CONCLUSION Shockwave lithotripsy is an effective and reliable treatment method in patients with congenital urinary system anomalies, especially when the stones are <2 cm. Patients with ureteral duplication had the overall best stone-free rates. However, patients who have stones > or =3 cm in horseshoe or malrotated kidneys and duplex systems seem to be better candidates for percutaneous nephrolithotomy or open surgery.

Abstract
OBJECTIVE In this study, 1121 patients with lower ureteral stones were evaluated to compare the effectiveness of extracorporeal shockwave lithotripsy (SWL) and ureteroscopy with three different lithotripsy modalities. METHODS Of these patients, 726 were treated with SWL, whereas 430 underwent ureteroscopy, with pneumatic lithotripsy (PL), ultrasonic lithotripsy (USL), and electrohydraulic lithotripsy (EHL) performed in 125 (29.0%), 276 (64.2%), and 29 (6.8%) patients, respectively. Thirty-five patients underwent both types of treatment because of unsuccessful SWL therapy. RESULTS In the SWL group, the stone-free rate was 42.2% and the fragmentation rate was 59.5%. These values were 96.8% and 98.4% for PL, 89.4% and 90.5% for USL, 93.1% and 96.5% for EHL, respectively. CONCLUSIONS These data show that SWL was less effective than ureteroscopic lithotripsy (p < 0.001). The PL modality had the highest stone-free and fragmentation rate, and EHL had the highest complication rate (43.5%). Ureteroscopic lithotripsy is the most effective treatment choice in lower ureteral stones no matter which kind of energy is used, and PL is the most effective and least morbid approach.

Abstract
This study investigated the efficacy and the adverse effects of sertraline in the treatment of premature ejaculation (PE). Thirty-seven patients with PE were randomly assigned to receive either sertraline or a placebo. Of them 22 were given 50 mg of sertraline per day and the other 15 patients were given an identical placebo one per day. After 4 weeks, the latency to ejaculation in the sertraline group was found to be significantly longer than that of the placebo group (p<0.01). None of the patients discontinued therapy due to adverse effects. These results indicate that sertraline is an effective therapy for PE.

Abstract
Transurethral electrovaporization of the prostate (TVP) has been introduced as an alternative to standard transurethral resection of the prostate (TURP) with lesser morbidity. However, the efficacy of this new technique has not been well known. To compare the results of standard TURP and TVP, 76 patients with symptomatic benign prostatic hyperplasia (BFH) were divided into two groups in a randomized clinical trial. Preoperative assessment included AUA Symptom score, maximum flow rates (Qmax), digital rectal examination, serum prostate specific antigen, and transrectal ultrasonography, with biopsy if the patient was randomized to vaporization. Transrectal temperature measurements and the hemoglobin concentration of the irrigation fluid were investigated in all the patients during the procedure. Although the transrectal temperature was higher in the TVP group (0.53-1.27 degrees C; mean 0.83 degrees C), no associated complication were determined. However, blood loss was significantly lesser than with TURP (340 mL v 60 mL). Two patients in the TURP group required blood transfusions, and one had sphincteric incontinence, whereas one postoperative retention, one reoperation with bladder perforation, and one sphincteric incontinence were seen in the TVP group. On the other hand, 12-month follow-up demonstrated that the uroflow rates improved in a similar manner. The Qmax increased in the TURP and TVP groups from 8.8 and 8.3 mL/sec to 19.6 and 17.2 mL/sec, respectively. The mean AUA Symptom Score decreased from 13.7 to 7.9 and 6.1 at 6 and 12 months, respectively. In the TVP group and from 14.6 to 7.3 and 7.0 at 6 and 12 months, respectively, in the TURP group. There were significant differences in the mean catheterization time (P < 0.0001) and hospital stay (P < 0.0001) in favor of TVP. Our results suggest that TVP is a safe and effective alternative treatment for symptomatic BPH.

Abstract
AIM OF THE STUDY The aim of the study is to compare the effectiveness of ESWL and ureteroscopic lithotripsy with pneumatic, ultrasonic and electrohydraulic modalities in patients with ureteral stones. PATIENTS AND METHOD In this study, 1,970 patients with ureteral stones were evaluated. ESWL and ureteroscopic lithotripsies were performed in 1,580 and 484 patients, respectively. The ESWL group was treated with a Siemens Lithostar plus. Ureteroscopic lithotripsy was performed with pneumatic lithotripsy (PL), ultrasonic lithotripsy (USL) and electrohydraulic lithotripsy (EHL) in 140 (28.9%), 311 (64.3%) and 33 (6.8%) patients, respectively. 94 patients underwent both because of unsuccessful ESWL therapy. RESULTS In the ESWL group, the stone-free rate was 49.9% and the fragmentation rate 71.0%. These values were: 95.0 and 97.1% for PL; 88.1 and 89.4% for USL; 90.9 and 93.9% for EHL, respectively. Ureteroscopic lithotripsy has been found more effective than ESWL in the treatment of middle and lower ureteral calculi (p < 0.001) and PL has the greatest success rate within these endoscopic groups. CONCLUSION ESWL therapy can be the first-line therapy in upper ureteral stones keeping the other modalities for unfragmented stones. However, ureteroscopic lithotripsy is the most effective treatment choice in lower ureteral stones no matter which kind of energy used and PL is the most effective and less complicated among the other types.

Abstract
OBJECTIVE The aim of the study is to determine the effectiveness of extracorporeal shock wave lithotripsy (ESWL) therapy for isolated lower caliceal calculi. PATIENTS AND METHODS We analyzed 165 patients who were treated with the Siemens Lithostar Plus on an outpatient basis between March 1993 and August 1997. The age of patients ranged from 17 to 70 (mean 39.11) years. The stone size varied from 4 to 42 mm, and patients who had stones larger than 21 mm had a double-J stent inserted prior to treatment. RESULTS The overall stone-free rate at 3 months was 53.33%; whereas it was 61.79, 48.27, and 27.27% according to the stone size, </=10, 11-20 and >/=21 mm, respectively. Complications were rare, including 2 pyelonephritis, 2 subcapsular hematoma formation, 24 renal colics and 8 stone streets, which were managed by ureteral stenting or additional ESWL and resulted in complete stone clearance. CONCLUSION ESWL therapy is a reasonable and effective method for small lower caliceal stones, but due to its relatively low stone-free and high complication rates, percutaneous nephrolithotripsy or open surgery should be considered for stones larger than 21 mm.

Abstract
OBJECTIVES The correlation between infertility and morphofunctional alterations following vasal occlusion is not clearly understood. Although a correlation has been found between the expression of a high titer of antisperm antibodies and the status of infertility, the relationship between the immunoglobulin (Ig) depositions in the testis and ultrastructural alterations of the peritubular structures has not been clearly established. The objective of this study is to explain the etiopathogenesis of diffuse and focal testicular lesions caused by vasal obstruction. METHODS Unilateral vasectomy was performed on adult male rats. Ultrastructural changes of testicular tissues and immunostaining affinity of peritubular structures with anti-actin, anti-vimentin, anti-laminin, and anti-immunoglobulin G (anti-IgG) antibodies were analyzed. RESULTS In an ultrastructural study, vasectomized animals presented abundant collagen fibril accumulation in the peritubular area. In testis with intense IgG antibodies, staining revealed weak immunostaining of peritubular myoid cells with anti-actin antibodies, but intense immunostaining with anti-vimentin antibodies. The tubules of rats with no IgG deposition on peritubular structures revealed intense immunostaining with anti-actin antibodies but scant immunostaining with anti-vimentin antibodies. Anti-laminin deposits decreased severely in most of the tubules demonstrating intense IgG deposition. CONCLUSIONS Our findings suggest that spermatogenesis deteriorates more severely in testes with dense IgG deposition. The sclerosis of the lamina propria in cases with vasal occlusion is secondary to alterations in the peritubular myoid cells. With the progressive changes that occur in the peritubular myoid cells or differentiation of the peritubular myoid cells that acquire active cell characteristics, collagen accumulation adjacent to these cells increases markedly. The alterations of the peritubular myoid cells reported here may be caused by alterations in basement membrane structures.

Abstract
Fresh operative cells from 27 renal cell carcinomas (RCC) were cultured in vitro for the determination of in vitro drug sensitivity. Two samples were not culturable. Incubation was carried out in triplicate in the presence and absence of various concentrations of chemotherapeutic agents. Sensitivity of the tumour cells to interferon-alpha (IFN-alpha), cisplatin (CDDP), mitomycin C (MMC), vinblastine (VBL), doxorubicin (DOX), etoposide (ETOP), bleomycin (BLM), vincristine (VCR) were tested by a colorimetric assay using MTT. A preexposure viability over 75% was essential for in vitro drug sensitivity assay (IVDSA). Sensitivity was determined by a more than 50 +/- 2 SD% reduction from the control absorbance. All eight drugs in their low concentrations exhibited cell proliferation inhibition in 0-12% of RCCs. On the other hand, IFN-alpha in its higher concentration (60 IU/ml) was effective in 88% of RCCs. After IFN, CDDP was found to be the second most effective drug in its higher concentration (36% efficacy). The results indicate that IFN appears to be the most effective in vitro agent in our 25 RCCs and the clinical trials either as a monotherapy or multiple combinations of various agents should include IFNs for the treatment of RCC.

Abstract
OBJECTIVE To investigate the association between cigarette smoking and sex hormone concentrations in men with benign prostatic hyperplasia (BPH) and thus provide some understanding of the underlying mechanism of the effects of cigarette smoking on prostatic enlargement. PATIENTS AND METHODS The association between cigarette smoking and prostatic volume was investigated in 68 men with BPH (mean age 59 years, range 52-74) by assessing changes in serum levels of oestradiol, testosterone, dihydroepiandrosterone (DHEA) and dihydroepiandrosterone sulphate (DHEA-S). Possible enzymatic mechanisms in the prostate gland that might be affected by cigarette smoking were assessed. RESULTS The mean prostate volume was greater in non-smokers than smokers. Current cigarette smokers had significantly higher mean serum oestradiol levels than did the non-smokers (33.8 and 26.7 pg/mL, respectively, P < 0.01). Cigarette smoking was inversely but not significantly related to testosterone level. These differences persisted after adjusting for body mass index. There was no significant difference in serum DHEA and DHEA-S levels between smokers and non-smokers. There was a weak correlation between the degree of prostatic enlargement, the presence of obstructive symptoms and urinary flow rates. CONCLUSION These results indicate that cigarette smoking may affect the size of the enlarging prostate, but through indirect effects of smoking on factors provoking the development of BPH.

Abstract
In spite of the significant advances in the chemotherapy of germ cell neoplasms, some patients do not achieve disease-free status and ultimately die from their diseases. Therefore, it is reasonable to select the best chemotherapeutic agents in these patients by in vitro drug sensitivity assay (IVDSA) in order to apply the most effective agent in case of resistance to primary chemotherapy. Fresh operative cells from 12 testicular germ cell tumours (TGCT) were cultured in vitro. Sensitivity of the tumour cells to interferon-alpha (IFN-alpha), cisplatin, mitomycin C, vinblastine, doxorubicin, etoposide, bleomycin, vincristine (VCR) were tested by a colorimetric assay using MTT. A preexposure viability over 75% was essential for IVDSA. Sensitivity was determined by a more than 50 +/- 2 SD% reduction from the control absorbance. All eight drugs in their high concentrations exhibited cell proliferation inhibition in 83.3 +/- 100% of TGCT. But in low concentrations efficacy of IFN and VCR were found to be lower than the others (33.3% and 58.3%, respectively). The results indicated that although TGCT are highly sensitive to various agents IVDSA may help to identify the effective agents which might be necessary for second line chemotherapy in a small percentage of patients.

Abstract
Infertility may occur in patients with unilateral testicular torsion whose contralateral testis is intact. Depending on this observation, the physicians have begun to examine the contralateral testis. In the present prospective study we aimed to examine the histopathologic alterations occurring in the contralateral testicle with time. Sixty adult male albino rats were included in the programme, and following experimental torsion the histopathologic findings, especially those in the contralateral testis, were evaluated after 4-12 weeks. Long-term and high degree torsion of the testicle led to varying degrees of deterioration in the germinal epithelium and interstitial cells of the contralateral testicle. Histopathologic alterations were reversed in 12 weeks. Tubular diameter and testicular volume also decreased in accordance with the histopathologic alteration. In our opinion, orchiectomy following torsion of one testicle will limit potential histopathologic alterations in the contralateral testicle.

Abstract
To evaluate the degree of ischemia formation in the contralateral testicle following unilateral testicular torsion, free oxygen radical formation after detorsion or an orchiectomy procedure in terms of superoxide dismutase (SOD) and catalase activities was detected in adult male Wistar rats. Animals were divided into 4 groups and following 2 and 6 h of unilateral torsion, the orchiectomy or detorsion procedures were performed and free radical scavenger enzyme activities (SOD, catalase) were measured in the contralateral testes after 24 h, 1 week and 1 month. Evaluation of our results revealed no meaningful ischemia formation in the contralateral testes of rats undergoing 2 h of unilateral testicular torsion. However, animals undergoing 6 h of unilateral testicular torsion demonstrated a statistically significant alteration with respect to enzyme concentrations. Alterations in the contralateral testes were more prominent in animals that had undergone the detorsion procedure following 6 h of testicular torsion. Our results indicate that preservation of twisted testes through a detorsion procedure could cause further deterioration by way of reperfusion injury, indicating the importance of removal of the damaged testicle to minimize long-term histopathologic alterations in the contralateral testes.

Abstract
To evaluate the fragility of Ca-oxalate monohydrate stones in terms of high energy shock wave effectivity, we measured the glycosaminoglycan (GAG) content of the organic stone matrix of 35 patients who had undergone extracorporeal shock wave lithotripsy (ESWL) treatment for renal pelvic stones. The patients were classified into 3 different groups with respect to the rate of stone disintegration. While group I consisted of patients in whom only one ESWL session was needed to complete disintegration, in group II there were patients requiring 3 or more sessions for complete stone disintegration. On the other hand, patients in whom no sign of disintegration was observed despite 3 ESWL sessions constituted group III. Following this procedure, comparative evaluation of the GAG content of the stone matrix per dry stone weight in each group revealed a statistically significant difference between the first 2 and the 3rd group (p < 0.05). Our results indicated that as the GAG content of the stone matrix decreased, the efficiency of the shock waves on stone disintegration also prominently decreased, disintegration being impossible in some cases. On the other hand, the stones which were found to have higher amounts of GAGs in the organic matrix tended to be more fragile and were easily disintegrated with shock waves. In our study group the chemical composition of Ca-oxalate monohydrate stones, e.g. the matrix GAG content, seemed to be important with regard to the disintegrative effect of high energy shock waves.

Abstract
In 68 men with benign prostatic hyperplasia, we evaluated the association between obesity and prostatic enlargement, as well as changes in serum levels of oestradiol, testosterone, dihydroepiandrosterone and dihydroepiandrosterone sulphate. Despite the larger adenomas, no increase in the symptom score for BPH was observed with increasing obesity. Average specimen weights increased with increasingly obesity and increasing host age from 46 to 80 g. We also found the serum oestradiol level significantly elevated in obese men who were 140% or over recommended weight compared to underweight men younger than 60 years (51.3 pg/ml versus 26.8 pg/ml, p < 0.01). This pattern was present in all age groups. These results indicate that obesity is a risk factor for prostatic enlargement but not for obstruction. Also the degree of obesity appears to have a direct effect on oestradiol levels through transformation of androgens in adipose tissue to oestrogens. In conclusion, further studies to evaluate the pathogenesis, pathophysiology, natural history and symptomatology of BPH would be of great interest and should help to define better the associations that we have recognized.

Abstract
To evaluate the possible effect of urinary tract infection (UTI) on the fragility of calcium-containing stones (calcium-oxalate, calcium-phosphate), the results of extracorporeal shock wave lithotripsy (ESWL) therapy in 81 patients with UTI and 30 patients with no sign of UTI were comparatively evaluated. ESWL parameters (shock wave number, kilovolt value, treatment time) and stone-free status during 3 and 6 months of follow-up were assessed for each patient, and the results were evaluated with respect to stone presence. Our results indicated that the presence of UTI may decrease stone fragility and increase stone clearance time. We believe that deterioration of peristaltic dynamics in the renal pelvis and the ureteral wall may reveal prolonged stone clearance phases in such patients.

Abstract
To evaluate the extent of renal parenchymal injury following high energy shock wave (HESW) application we measured the urine levels of two renal tubular brush border enzymes: leucine aminopeptidase (LAP) and gamma-glutamyltranspeptidase (GGT) the day before, 24 hours and 7 days after extracorporeal shock wave lithotripsy (ESWL) in 23 patients. All patients had caliceal stones and were treated with a Dornier MPL 9000 lithotriptor under sedoanalgesia. Creatinine concentration of each sample together with total shock wave effect (TSWE) values were also assessed and comparatively evaluated with enzymuria levels. Our results indicated a statistically significant rise in urinary excretion of both enzymes after 24 hours following lithotripsy (p < 0.05). All these values returned to normal limits within 7 days after ESWL (p > 0.05). Transient tubular damage due to HESW was found to be related to TSWE values assessed in our group.
