Comparison of penile prosthesis types' complications: A retrospective analysis of single center.

OBJECTIVES: The aim of this study was to compare clinical outcomes and complication rates associated with semirigid (malleable) and inflatable penile prostheses (PPs) and investigate the factors that influence these complications. MATERIAL AND METHODS: The records of 131 patients who had undergone penile prosthesis implantation (PPI) in our clinic due to erectile dysfunction (ED) between January 2010 and March 2019 were retrospectively reviewed. The initial surgery included 116 primary implants and 15 men had two revision operations. Patients were assigned to two groups as semirigid (malleable) PPI (group 1) and inflatable PPI (group 2) patients, and obtained data were compared across these two groups. RESULTS: Group 1 included 93 patients, while Group 2 included 38 patients. Postoperative complication rates of Group 1 were 8.6% (n = 8), and Group 2 were 21% (n = 8), and the comparison of postoperative complication rates revealed a statistically significant difference between the two groups (p = 0.025). The majority of these complications (50%) was constituted by mechanical failure associated with inflatable PPs. When patients were further segregated as those with and without diabetes type 2 (DM) and those who had and had not undergone radical pelvic surgery (RPS), the comparison of complication rates across these subgroups did not yield any significant difference. CONCLUSIONS: We determined in this study that semirigid (malleable) PPs were associated with lower complication rates compared to the inflatable group, particularly with regard to mechanic failure, and that DM and history of RPS did not make a difference in complication rates in patients planned to undergo PPI.

Effect of Kidney Volume on the Results of Nephrectomy Performed for Xanthogranulomatous Pyelonephritis.

Aim This study aims to evaluate the results of patients we treated with nephrectomy due to Xanthogranulomatous pyelonephritis (XGP) and the effects of kidney volume on the results. Patients and methods Records of 22 patients who underwent nephrectomy due to renal masses at our clinic between January 2008 and May 2018 and whose pathology results indicated XGP were retrospectively evaluated. The computed tomography (CT) measurement of the kidney volumes of the patients was calculated as the product of the longest length, width, and height of the kidney. The mean kidney volume of the patients was calculated and the patients were distributed into two groups: those that presented volumes below average (Group 1) and above average (Group 2). The patients' mean ages, operative duration, hospitalization days, differences in pre- and postoperative hemoglobin and creatinine levels, and postoperative complications were compared across groups. Results Group 1 consisted of 12 patients and Group 2 of 10 patients. The mean kidney volume of the patients was calculated as 33.4 cm3 ± 26.0 cm3. The mean kidney volume of the patients was 15.8 cm3± 9.9 cm3 in Group 1 and 56.8 cm3 ± 21.8 cm3 in Group 2. There were no statistical differences between the two groups in terms of operative times, preop-postop hemoglobin (Hgb) levels and complications. Conclusion In cases where XGP is considered probable, the priority in preoperative CT must be to thoroughly evaluate the relationship of the kidney with the surrounding tissue and organs rather than to investigate the patients' kidney volumes.

Percutaneous nephrolithotomy in patients with a solitary kidney.

MATERIAL AND METHOD: The results of percutaneous nephrolithotomy applied to 716 patients in our clinic between January 2008 and January 2014 were retrospectively evaluated. Age, gender, urinary calculi size (mm(2)), urinary calculi localization, ESWL history, operation duration (min), fluoroscopy duration (sec), access type, reason of solitary kidney, hemoglobin drawdown (g/dl) and operation success of the patients with a solitary kidney were recorded. The patients having no preoperative and postoperative non contrast abdominal tomography were excluded from the study. RESULTS: Fifteen of nineteen patients (79%) were men and 4 of them (21%) were women. The average age of the patients was 42.52 ± 16.72 (14-72). Ten patients had anatomical solitary kidney and nine patients had physiological solitary kidney. In fact counter kidney was non functional in 9 patients (47%) whereas there was agenesis in 2 (11%) and outcome of nephrectomy in 8 (42%) patients. In our study, presence of residual stone less than 4 mm at 1st month postoperative non contrast abdominal tomography was accepted as a successful result and accordingly our success rate was detected as 84%. Mean urinary calculi size was 405 ± 252.9 mm(2); urinary calculi localization was pelvic, lower pole, upper-middle pole, middle-lower pole and staghorn in 11 (58%), 4 (21%), 1 (5%), 1 (5%) and 1 (5%) patients, respectively; previous ESWL history was 16%; operation duration was 55.47-± 28.1 min and fluoroscopy duration 131.10 ± 87.6 sec; access type was subcostal in 79%, supracostal in 10.5% and multiple in 10.5%; hemoglobin drawdown was 1.75 ± 0.97 mg/dl. CONCLUSIONS: PNL can be effectively and safely administered for the treatment of solitary kidney. In the treatment of large urinary calculi in patients with a solitary kidney, PNL has some advantages such as short surgery duration, less complication, acceptable hemoglobin drawdown and high success rates. According to our study, PNL operation in patients with a solitary kidney is a good option for carefully and poisedly selected cases.

Hormonal and pathologic changes after chemoablation of testes with hypertonic saline solution as a treatment method alternative to orchiectomy in patients with hormone sensitive metastatic prostatic cancer.

OBJECTIVE: We tried to clarify whether less invasive and lower-cost method of injecting hypertonic saline solution could be an alternative to orchiectomy. MATERIALS AND METHODS: Thirty adult healthy male Wistar rats were used as experimental animals. Three groups were made as 0.9% NaCl administered to the first group, orchiectomy performed to the second group, and 20% saline solution administered to the third group. To measure baseline testosterone values were obtained from all rats 1 day before the procedure. Blood samples obtained to analyze total testosterone from all rats at days 1, 15, and 60 were centrifuged and stored in deep freeze. After blood samples were obtained at day 60, intramuscular 100 IU HCG (Pregnyl) was administered to all rats. Following HCG injection, new blood samples were obtained to analyze testosterone levels at 120 minutes. RESULTS: On microscopic examination, while extensive coagulation necrosis was seen in the third group, in only two samples in this group, an area of intact tissue was observed. Baseline, day 1, day 15, and month 2 testosterone levels of all groups were analyzed. When changes in testosterone levels between baseline values and month 2 control levels were compared, changes in the second and third group were detected statistically significant, and there was no statistically significant difference between these two groups. When month 2 and post-HCG stimulation test serum testosterone levels were compared, a statistically significant increase was found only in the first group. CONCLUSIONS: These data indicate that since there are nearly the same pathological and biochemical results with bilateral orchiectomy and no negative findings were found for comorbidity, bilateral injection of 20% hypertonic saline solution into the testes could be an alternative in the treatment of hormone-sensitive metastatic prostate cancer.
