Outcome of penile prosthesis implantation: are malleable prostheses an appropriate treatment option in patients with erectile dysfunction caused by prior radical surgery?

The aim of our study was to evaluate the outcome of penile prosthesis implantation in patients with various comorbidities as a cause of erectile dysfunction (ED). The data of 181 patients who underwent surgery between 1998 and 2012 in two centers were evaluated. The mean age of the patients was 52.2 years (range: 31-71 years). The study group contained 162 patients (89.5%) with malleable prostheses and 19 (10.5%) with inflatable implants. All patients were re-evaluated 1 month later to assess prosthesis function and complications, and further re-examinations were performed if needed. Satisfaction was defined as having satisfactory intercourse and happiness with the device in general. The follow-up period was at least 12 months for each patient. The postoperative complication rate was 32% (n = 58). The number of complications with inflatable and malleable prostheses was 7 (3.9%) and 51 (28.1%), respectively. Overall, 21 prostheses (11.6%) had to be removed because of various complications and patient dissatisfaction. Patients with prior radical surgery had higher extraction rates (ƛ = 14.606, P < 0.05, Chi-square test). The main reasons for removal were erosion (n = 11; 6.1%) and infection (n = 3; 2.1%). With respect to satisfaction during intercourse, we found that 104 (57.5%) patients described themselves as very satisfied with the prosthesis, while 21 (11.6%) were unsatisfied. The high explantation rate in patients with prior surgery was remarkable in our study. Our results revealed that a malleable prosthesis should not be the preferred type of implant for patients with prior surgery.

Hand-assisted laparoscopic and laparoscopic donor nephrectomy: A comparison of surgical outcomes from two centres

OBJECTIVE The aim of the study was to compare the different surgical approaches of two centers on outcomes of live donor laparoscopic nephrectomy. MATERIAL AND METHODS The first 98 patients of each centre who underwent laparoscopic donor nephrectomy (LDN) or hand-assisted laparoscopic donor nephrectomy (HALDN) were included in the study. The following data were used for analyses: donor age, weight, height, body mass index (BMI), transfusion requirement, operative time, ischemia time and postoperative complications. RESULTS Median age, BMI, operation time and estimated blood loss (EBL) was 47.29 years, 27.91 kg/m2, 110.73 minutes, and 78.95 mL, respectively. Operation time was significantly shorter in the HALDN group (t=-3.554, p<0.01). EBL was not significantly different between the two groups. The difference in hospitalization time and warm ischemia times (WIT) was not significant between the two surgical technique groups (t=-1.554, t=1.258; p>0.05). No statistically significant difference was detected in the intraoperative and postoperative complication rates between two groups (p>0.05). The postoperative complication rate was 7.14% (n=7) and 6.12% (n=6) in the LDN and HALDN groups, respectively. There were two patients with conversion to open surgery in the HALDN group because of lumbar vein injury. CONCLUSION The operative and postoperative outcomes for the two techniques were found to be similar. The HALDN technique preserves the benefits of minimally invasive surgery. In experienced urologic laparoscopy centres both techniques promise similar success rates.

Minimally Invasive Approach To Ureteral Stricture in Transplant Kidney by Periodic Retrograde Ureteral Stent Placement and Exhange

PURPOSE The aim of the study was to evaluate the effectiveness of minimally invasive treatment of ureteral strictures and describe the technique that we used for retrograde placement of ureteral stent in transplant kidneys. MATERIAL AND METHODS We reviewed the medical cards of all transplant kidney patients with persistent ureteral strictures who were managed with periodical ureteral stent placement and balloon dilatation between 2008 and 2016. Different maneuvers that were used to overcome the difficulties for retrograde ureteral stent placement and exchange were discussed. Clinical characteristics and treatment outcomes of the study cohort were analyzed. RESULTS Between 2008 and 2016, a total of 1026 transplantations were performed in our clinic, and ureteral stricture was found in 13 patients (1.26%). Of the 13 patients, 8 were treated with periodic ureteral stent insertion and balloon dilatation. Ureteral stent insertion or stent exchange was performed in 52 transplant renal units. The overall success rate of retrograde ureteral stent insertion at the first attempt was 75% and stent exchange success rate was 100%. Renal function remained stable in all patients during a median follow-up of 41 months (range, 13-60 months). No other local or systemic complication was encountered and no stent encrustation was noted. CONCLUSIONS Endoscopic management of ureteral stricture by periodical retrograde ureteral stent replacement and balloon dilatation is safe, effective, and highly successful in transplant patients who are not eligible for open reconstructive surgery.

Salvage urethroplasty using skin grafts for previously failed long-segment urethral strictures.

The aim of this study was to describe a technique using full‐thickness skin grafts (FTSGs) from different parts of the body for salvage urethroplasties and the present outcomes. A total of 24 men underwent urethroplasties for strictures averaging 7.7 cm (range, 5–17 cm) in length, using FTSGs from the inner arm, inner thigh, or abdominal skin. Each of these cases had at least one failed urethroplasty. Twenty‐four patients underwent surgery for 26 urethral strictures, with a mean follow‐up period of 23.2 (5–44) months and a mean operation time of 140 (115–180) minutes. Reconstruction of the urethra with skin grafting was successful in 18 out of the 26 procedures during the first attempt (69%). A “redo” skin grafting was performed for the eight failed cases, with four successful procedures (50%). Overall, the success rate was 84% (22 out of 26 urethral strictures); however, the failed cases developed abscesses and later, ureterocutaneous fistulas. No hair formation from the skin grafts was seen. Skin grafts provide useful alternative graft sources for previously failed long‐segment urethral strictures in which the buccal mucosae are not available or are insufficient for salvage urethroplasties with an acceptable success rate.

The relationship of enuresis nocturna and adenoid hypertrophy.

OBJECTIVES This study was organized to assess the relationship of enuresis nocturna (EN) and upper airway obstruction (UAO) in children. MATERIAL AND METHODS This study was multi-centrically and prospectively designed including 79 children who presented to a urology clinic with symptoms of EN between January 2013 and February 2014. Sixty-four age-matched children with no history of urological complaints were randomly recruited from children admitted to a pediatric clinic as a control group. All children and parents were asked to fill out a dysfunctional elimination syndrome (DES) questionnaire and children were examined by an ear, nose and throat (ENT) specialist to evaluate the UAO. Descriptive statistics, chisquare and Mann-Whitney-U tests were used to compare variables. RESULTS The mean ages of the 79 children (48 male, 31 female) in the study group and the 64 children (41 male, 23 female) in the control group were 10.14+/-3.38 and 9.17+/- 2.85, respectively. Family history of the study showed that 19% of the childrens mothers, 10% of the childrens fathers and 37% of the childrens siblings had experienced EN. There was a significant difference between the study and the control groups in terms of urge to urinate, bladder emptying, bowel symptoms and psychological stress. There was also a significant difference between rates of tonsillar hypertrophy and nasopharynx obstruction in the EN group (p = 0.009). CONCLUSION In this study we found that half of the children with EN had tonsillar hypertrophy, which was significantly higher than in the control group. Further studies are needed to clarify the exact relationship between UAO and EN.
