Surgical management of female paraurethral cyst with concomitant stress urinary incontinence.

Paraurethral cysts are usually asymptomatic and frequently detected incidentally during routine pelvic examination however, patients can present with complaints of a palpable cyst or with lower urinary tract symptoms (LUTS) and also dyspareunia. In most cases, diagnosis can be made on physical examination but for more detailed evaluation and to differentiate from malign lesions ultrasonography (US), voiding cystourethrogram (VCUG), computerized tomography (CT), or magnetic resonance imaging (MRI) can also be used. Management of symptomatic paraurethral cyst is surgical excision. In this video our objective is to show the surgical management of female paraurethral cyst with concomitant stress urinary incontinence (SUI). A 37 year-old woman presented with an 8-year history of progressive urinary symptoms, consisting of dysuria, urinary frequency, urgency urinary incontinence, SUI and dyspareunia. Physical examination in the lithotomy position revealed a cystic lesion located in the left anterolateral vaginal wall. Also cough stress test for SUI was positive. Her preoperative ICI-Q, UDI-6, IIQ-7 and SEAPI scores were 16, 8, 9 and 18 respectively. Vaginal US revealed a solitary 2 cm paraurethral cyst, localized in the distal urethra. Pelvic MRI also revealed a benign cystic lesion in the distal urethra. The patient underwent surgical excision of the cyst and anterior colporrhaphy for SUI. At third month visit the patient was very satisfied. The ICI-Q, UDI-6, IIQ-7 and SEAPI scores were 0. Sometimes the LUTS concurring with the parauretral cyst can be dominant. Herein we want to show that extra surgical procedures can be necessary with paraurethral cyst excision for full patient satisfaction.

Synchronous penoscrotal implantation of penile prosthesis and artificial urinary sphincter after radical prostatectomy.

OBJECTIVES: To evaluate the results of synchronous dual implantation of penile (PP) and artificial urinary sphincter prosthesis (AUSP) in patients with severe erectile dysfunction (ED) and urinary incontinence (UI) after radical prostatectomy (RP). METHODS: Between January 2006 and March 2015, patients who underwent synchronous dual implantation of PP for severe post-RP ED and AUSP for moderate to severe post-RP UI in our clinic were screened retrospectively. The erectile function and the continence status were evaluated by the questionnaires of IIEF-5 and ICIQ-SF. Results for the preoperative period and for the 1st postoperative year were revealed from patient charts. Long term results were evaluated by telephone interviews. Comorbidities, infection rates and complications were noted. RESULTS: A total of 14 patients underwent synchronous dual implantation; out of which, 11 had a long enough follow up period for a sufficient long term evaluation. 3/11 had MPP and 8/11 had two-piece IPP implantation together with an AUSP. All of the implantations were carried out through an upper transverse scrotal incision. Mean follow up time was 61.3 ± 20 months. In 1 patient who had received adjuvant radiotherapy, both of the devices were removed due to infection and cuff erosion. Mean daily usage of pads diminished from 4 to 1 while ICIQ-SF score decreased from 19 to 2 and IIEF-5 score increased from 3 to 23. CONCLUSION: Synchronous implantation of PP and AUSP is a safe and effective treatment option for patients with severe ED and moderate to severe UI after RP.

An update of Penile Fractures: Long-term significance of the number of hours elapsed till surgical repair on long-term outcomes.

OBJECTIVE: We updated our data on penile fractures and investigated the significance of the time interval from the incident of the fracture until the operation on the erectile functions and long-term complications. MATERIAL AND METHODS: Between January 2001 and June 2014, 64 patients were operated on with a preoperative diagnosis of penile fracture. We could evaluate 54 of these patients. The patients were classified into 3 groups according to the time interval from the time of fracture until surgery. The validated Turkish version of the erectile components of International Index of Erectile Function (IIEF) was answered by every patient 3 times after the surgery; before the incident of fracture, at first postoperative year, and at the time of the study (IIEF-5 and question #15 were used). The complications were noted and an erectile function index score was calculated for every patient. RESULTS: Mean follow up period was 44.9 (±2.8) months for all patients There was no statistically significant difference between the 3 groups in terms of the erectile components of IIEF questionnaire scores for the time periods and for individual patients in each separate group. Complications for all groups were also similar. CONCLUSION: In consideration of long-term results, neither serious deformities nor erectile dysfunction occur as a consequence of a delay in surgery performed within the first 24 hours in patients without urethral involvement.

Neutrophil to Lymphocyte Ratio as a predictor of early penile prosthesis implant infection.

PURPOSE: To investigate the predictive value of preoperative serum neutrophil-to-lymphocyte ratio (NLR) on the development of postoperative infections in patients undergoing penile prosthesis implantation (PPI). METHODS: We retrospectively analyzed the data of 361 patients who underwent PPI over a 4-year period with at least 1-year follow-up. Demographics, blood results, and postoperative 1-year complications were recorded. Recommended cutoff values of NLR for early postoperative infectious complications were determined using receiver operating characteristic analysis. RESULTS: A total of 153 patients with the mean age of 56.4 ± 8 years were included in the study. Mean follow-up time was 56.7 ± 30.4 months (12-108 months). Early postoperative infectious complications were occured in 18 patients (11.8%). These infections were prosthesis infection in 8 patients (5.2%), wound infection in 6 patients (3.9%), and urinary tract infection in 4 patients (2.6%). All these complications were occured within the first year of the surgery. Mean NLR was statistically higher in patients with postoperative complications when compared with uncomplicated cases (7.2 ± 3.9 vs. 2.2 ± 1.4, p < 0.001, respectively) Using a cut point of 6.2, preoperative NLR predicted postoperative complications with a sensitivity of 67% and specificity of 99%. CONCLUSIONS: This study is the first to investigate the relationship between NLR and early postoperative infection as a complication of PPI. The results demonstrated that the NLR value could be a potential laboratory parameter for predicting early postoperative infectious complications in patients undergoing PPI.

Laparoscopic adrenalectomy for large adrenal masses: Is it really more complicated?

Laparoscopic treatment of large adrenal tumors is still questionable due to concern over the risk of malignancy as well as the technical difficulties. No exact dimensional cut-off has been described for laparoscopic adrenalectomy (LA). In this study, we reviewed our experience with LA for masses ≥ 8 cm and tried to determine the limitations of this surgery in this group of patients. Sixteen patients with adrenal mass ≥ 8 cm (Group 1) and 19 patients with adrenal mass < 8 cm (Group 2) treated with transabdominal LA were included in this study. We analyzed operative time, intraoperative and postoperative complications and length of postoperative hospital stay with respect to tumor size and clinopathologic features. Mean maximum tumor diameters were 91.7 mm (range, 80-150 mm) and 52.4 mm (range, 35-73 mm) in Group 1 and Group 2, respectively. Operation time and blood loss were higher in Group 1 compared to Group 2, but these differences did not reach significant levels (p>0.05). Conversion to an open procedure required in two patients, one from each group, because of the firm attachments of adrenal mass to the surrounding tissue. In conclusion, our study demonstrated that LA is a safe and feasible procedure for large lesions even up to 15 cm. The risk of finding incidental adrenal cortical cancer was significantly increased for large lesions in our series as in the literature; therefore, it is important to follow the strict oncological principles in these cases.

Use of a microdebrider for corporeal excavation and penile prosthesis implantation in men with severely fibrosed corpora cavernosa: a new minimal invasive surgical technique.

OBJECTIVE: To propose a new minimal invasive surgical technique using a microdebrider (shaver) to excavate the fibrosed corpora cavernosa for penile prosthesis implantation in patients with severe fibrosis. MATERIAL AND METHODS: Two patients with severe corporeal fibrosis were implanted with a penile prosthesis using this technique. In the first patient, fibrosis was due to neglected idiopathic ischemic priapism and the second patient had his prosthesis extruded because of erosion in another center. Both patients were counseled about the procedure and the possible complications related to the experimental nature of the technique. A written informed consent was obtained from both patients. Excavation of the corpora was performed using microdebrider in both patients. RESULTS: Both operations were performed successfully without any intraoperative complications, including urethral injury or perforation of the tunica. The mean operation time was 57 min. The postoperative period was uneventful without any infection, migration, erosion, or mechanical failure. The penile length was increased nearly 2 cm in both patients, and the penile girth was increased around 30% in the patient who underwent inflatable penile prosthesis implantation. CONCLUSION: The microdebrider potentially provides an important advance in patients with severe corporeal fibrosis to excavate the fibrosed corpora cavernosa for penile prosthesis implantation. The main advantages include fast, safe, and effective excavation of fibrous corpora cavernosa adequate for a satisfactory penile prosthesis implantation.

Patient and partner outcome of inflatable and semi-rigid penile prosthesis in a single institution.

INTRODUCTION: Penile prostheses are subject to a continuous development and have gained better mechanical reliability and safety during the last decades. In this study, we aimed to investigate the outcomes and satisfaction rates of inflatable penile prosthesis (IPP) and semirigid penile prosthesis (SPP) implantation. MATERIALS AND METHODS: From August 2001 to June 2012, 257 men with erectile dysfunction (ED) underwent penile prosthesis implantation (PPI) at our institution. Of the 257 patients, 118 underwent implantation of IPP and 139 underwent SPP implantation. The pre-operative and post-operative erectile status of the patients were assessed by international index of erectile function (IIEF) questionnaire. The satisfaction of patients and partners were evaluated by a telephone interview using the erectile dysfunction inventory of treatment satisfaction (EDITS) questionnaire and EDITS partner survey. RESULTS: The overall major complication rate was higher in IPP group. PPI led to a significant improvement in IIEF scores in both groups. For IPP and SPP groups the average EDITS scores were 78±11and 57±8, respectively, and that for the partners were 72±10 and 49±7, respectively (p<0.05). CONCLUSION: Although the IPP implantation have better satisfaction rates, the SPP implantation is still a viable treatment option in the surgical treatment of ED because of low cost and high durability with acceptable satisfaction rates.

Clinical features and outcomes of nontransitional cell carcinomas of the urinary bladder: Analysis of 125 cases.

OBJECTIVES: The aim was to evaluate pathologic diagnosis, treatment and prognosis of 125 patients with nontransitional cell carcinoma of the urinary bladder. MATERIALS AND METHODS: A total of 3590 patients with bladder tumors operated in our clinic between September 1998 and May 2013 were retrospectively evaluated. A total of 125 patients (107 men and 18 women) with nontransitional cell bladder cancer, confirmed by histopathology, were included in this study. The patients' characteristics, including age, gender, smoking history, tumor size, and localization, histological types, pathological tumor stages, treatment modalities, and survival rates were all recorded. RESULTS: Of these tumors, 47 (37.6%) were adenocarcinoma (AC), 42 (33.6%) were squamous cell carcinoma (SCC), 23 (18.4%) were undifferentiated carcinoma (UC), 13 (10.4%) were other types of bladder carcinoma. Sixty-three (50.4%) patients had undergone radical cystectomy and pelvic lymphadenectomy ± adjuvant treatment (chemotherapy [CT]/radiotherapy) and 52 (41.6%) patients received radiotherapy ± CT. The median survival time of patients with AC and SCC were significantly higher than patients with UC (AC vs UC, P = 0.001; SCC vs UC, P = 0.000; AC vs. SCC, P = 0.219). Median survival time was significantly higher in radical cystectomy ± adjuvant treatment group (P < 0.05) in all histological types. CONCLUSION: Prognosis of urinary bladder tumors was directly related to histological type and stage of the tumor. CT or radiotherapy has limited response rates. Early radical cystectomy should be performed to improve prognosis.

Is new visual prostate symptom score useful as International Prostate Symptom Score in the evaluation of men with lower urinary tract symptoms? A prospective comparison of 2 symptom scores in Turkish society.

OBJECTIVE: To evaluate the correlation between the visual prostate symptom score (VPSS) and the International Prostate Symptom Score (IPSS) and uroflowmetry parameters in Turkish men with lower urinary tract symptoms. MATERIAL: Between September 2013 and March 2014, a total of 191 patients who were admitted to the hospital with lower urinary tract symptoms were enrolled in the study. After the routine tests were performed, the patients were requested to fill the IPSS questionnaire consisting of 8 questions and the VPSS questionnaire consisting of 4 questions. Peak (Qmax) and average (Qave) urinary flow rates were measured. RESULTS: Mean age value was 62.8 years (range, 43-84 years). The education level was divided into 3 groups as follows: groups 1, 2, and 3 consisting of 98 patients (51.3%) with formal schooling (1-8 years education), 61 patients (31.9%) with 9-12 years education, and 32 patients (16.8%) with college or university education, respectively. There was a positive correlation between the total IPSS and the total VPSS (r = 0.72; P <.001). There was a negative correlation between the Qmax values and both the total IPSS (r = -0.53; P <.001) and the total VPSS (r = -0.3; P <.01), separately. The questionnaire was completed without any assistance by 25 (25.5%), 33 (54.1%), and 27 (84.4%) men for the IPSS and by 76 (77.6%), 54 (88.5%), and 31 (96.9%) men for the VPSS in groups 1, 2, and 3, respectively. CONCLUSION: The VPSS correlates significantly with the IPSS and can be reliably used in the elderly and low-educated patients for the assessment of symptom severity in men with lower urinary tract symptoms.

Risk factors for postoperative infectious complications following percutaneous nephrolithotomy: a prospective clinical study.

The aim of the study was to assess the preoperative and intraoperative potential risk factors for infectious complications after percutaneous nephrolithotomy (PCNL). A total of 303 patients who underwent PCNL for renal stones were included in the recent study. A detailed history including past renal surgery, nephrostomy insertion and recurrent urinary infection were obtained from all patients. Preoperative urine culture, renal pelvic urine culture and stone culture were obtained from all patients. The intraoperative data were prospectively noted. All patients were followed up postoperatively for signs of systemic inflammatory response syndrome (SIRS) and sepsis. In 83 (27.4%) of the patients, SIRS was observed and of these patients 23 (7.6%) were diagnosed as sepsis. Escherichia coli was the most common organism detected in cultures, followed by Pseudomonas aeruginosa, Enterococcus and Klebsiella spp. in all patients. By multivariate logistic regression analysis, presence of infection stone, stone burden and recurrent urinary tract infection were associated with both SIRS and sepsis development. Presence of infection stone, stone burden ≥800 mm(2) and recurrent urinary tract infection can be identified as independent predictors for the development of SIRS and sepsis.

Supracostal Approach for PCNL: Is 10th and 11th Intercostal Space Safe According to Clavien Classification System?

The purpose of this study was to evaluate the success and morbidity of percutaneous nephrolithotomy (PCNL) performed through the 11th and 10th intercostal space. Between March 2005 and February 2012, 612 patients underwent PCNL, 243 of whom had a supracostal access. The interspace between the 11th and 12th rib was used in 204 cases (group 1) and between the 10th and 11th interspaces in 39 cases (group 2). PCNL was performed using standard supracostal technique in all patients. The operative time, success rate, hospital stay, and complications according to the modified Clavien classification were compared between group 1 and group 2. The stone-free rate was 86.8% in group 1 and 84.6% in group 2 after one session of PCNL. Auxiliary procedures consisting of ureterorenoscopy (URS) and shock wave lithotripsy (SWL) were required in 5 and 7 patients, respectively, in group 1; and in 1 patient each in group 2 . After the auxiliary procedures, stone-free rates increased to 92.6% in group 1 and 89.7% in group 2. A total of 74 (30.4%) complications were documented in the 2 groups according to modified Clavien classification. Grade-I complications were recorded in 20 (8.2%), grade-II in 38 (15.6%), grade-IIIa in 13 (5.3%), and grade-IIIb in 2 (0.8%) patients; grade-IVa was recorded in 1 (0.4%) patient. There were no grade-IVb or grade-V complications. Overall complication rate was 30.9% in group 1 and 28.2% in group 2. Supracostal PCNL in selected cases is effective and safe with acceptable complications. The modified Clavien system provides a standardized grading system for complications of PCNL.

Does the etiology affect the outcome and satisfaction rates of penile prosthesis implantation surgery?

Our aim was to compare the outcomes and satisfaction rates of men undergoing penile prostheses implantation (PPI) secondary to radical prostatectomy (RP) and other causes of vasculogenic erectile dysfunction (ED). A total of 142 patients, of whom 60 underwent PPI due to ED following RP (Group 1) and 82 underwent PPI due to ED with other vasculogenic causes (Group 2) were included in this study. The preoperative erectile status was evaluated with the International Index of Erectile Function (IIEF). The satisfaction of patients and partners were evaluated by a telephone interview using Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) questionnaire and Erectile Dysfunction Inventory of Treatment Satisfaction Partner Survey. Preoperative mean IIEF scores were significantly lower in Group 1 (17.5 ± 6.4 vs. 24.2 ± 5.1, p = 0.01). For Groups 1 and 2, the mean EDITS scores of the patients were 58 ± 10 and 71 ± 8, respectively, and that for the partners were 46 ± 8 and 65 ± 7, respectively. Group 1 had significantly lower scores both for the EDITS and the EDITS Partner Survey (p = 0.03, p = 0.01, respectively). Patients who had undergone RP and their partners were found to have lower satisfaction rates compared to patients with other causes of vasculogenic ED who had penile implant surgery. From this point of view, it is important to know the patient's expectations about the treatment outcomes and a preoperative psychological and sexual counseling should be managed for possible treatment alternatives after RP.

Spontaneous bilateral rod fracture of malleable penile prosthesis.

Mechanical failure with a malleable penile prosthesis is very rare. To the best of our knowledge, this is the first case reporting on a bilateral AMS 650 rod mechanical failure. We present a 50-year-old man with organic erectile dysfunction who experienced bilateral AMS 650 rod fracture after 14 years. The rod fracture of the left side was confirmed via X-ray preoperatively. The surgical exploration revealed a fracture of both rods. After the removal of both rods, we implanted a new malleable device during the same session. At the 6-month follow-up, the patient was satisfied with his prosthesis.

Comparison of Ho:YAG laser and pneumatic lithotripsy in the treatment of impacted ureteral stones: an analysis of risk factors.

The aim was to compare pneumatic and holmium:yttrium-aluminum-garnet laser in the treatment of impacted ureteral stones with different locations and to identify the risk factors for complications. Between March 2005 and November 2012, a total of 230 patients underwent ureteroscopic lithotripsy for impacted stones. Of the patients, 117 had pneumatic and 113 had laser lithotripsy for the fragmentation of the stones. Treatment outcomes based on evidence of being stone free were evaluated. Preoperative, operative, and postoperative follow-up findings were analyzed and compared. There was a difference between the two groups according to overall stone clearance rate (93.8% vs. 80.3%, p = 0.002). There was no statistically significant difference for distal location between the laser and pneumatic groups (96.8% vs. 91.7%, p =0.288). For 10 patients with intrarenally migrated stones who were managed with flexible ureterorenoscopy in the same session, laser lithotripsy was more successful than pneumatic for proximal ureteral stone (94.4% vs. 67.9%, p = 0.007). The overall complication rate was 26.1%. There was no statistically significant difference between the two groups (29% vs. 23%, p = 0.296). Multivariate logistic regression analysis revealed that the proximal location was a statistically significant parameter for the occurrence of complications in both groups (p = 0.001 for PL, p = 0.004 for laser). The pneumatic and holmium:yttrium-aluminum-garnet laser lithotripsy are effective in the treatment of distal impacted stones. Both treatments with semirigid ureteroscopy are acceptable for proximal impacted ureteral stones, but holmium laser lithotripsy has an advantage of use with flexible ureteroscope for intrarenally migrated stone.

Are the outcomes of transobturator tape procedure for female stress urinary incontinence durable in long-term follow-up?

PURPOSE: To evaluate long-term cure rates and late complication rates after treatment for female stress urinary incontinence (SUI) with transobturator tape (TOT) procedure and to compare the outcomes of 1st year versus 5th year. METHODS: We analyzed 138 women who underwent TOT procedure for pure SUI and mixed urinary incontinence in two institutions during the time period of June 2005-May 2008 retrospectively. We used two kinds of polypropylene monofilament tapes (Heine Medizinurethral support system, Germany and I-STOPCL Medical, France) for the standard outside-in TOT in similar numbers. All patients were evaluated with pelvic examination including cough stress test and International Consultation on Incontinence Questionnaire-Short Form at 3 and 12 months and annually. Our primary outcome measures were rates of objective cure, subjective cure, patient satisfaction and failure for long-term follow-up. RESULTS: The objective cure, subjective cure and patient satisfaction rates of the 126 women at 1 year were 89.6, 86.5 and 92% respectively. During 5-year follow-up, objective cure rate was stable with 87.3% rate (p = 0.554), whereas subjective cure and patient satisfaction rates were decreased to 65.9 and 73%, respectively (p = 0.001). Complications are reported according to the Clavien-Dindo classification with Gr I 14.3%, Gr II 64.3%, Gr IIIa 7.1% and Gr IIIb 14.3 %. CONCLUSIONS: TOT procedure is an effective minimal invasive procedure with satisfactory results for female SUI in short term. Although recovery in SUI symptoms was stable during 5-year follow-up, subjective cure and patient satisfaction rates decreased significantly due to urge urinary incontinence symptoms.

Factors affecting the complications of pneumatic lithotripsy for the treatment of ureteral stones with different localizations: a multivariate analysis of complications.

OBJECTIVE: To evaluate the complications of ureterorenoscopy (URS) using the modified Clavien classification system for ureteral stones with different localizations. PATIENTS AND METHODS: From February 2001 to January 2010, a total of 1,926 patients underwent URS for the treatment of ureteral stones with different localizations. The complications were evaluated according to the modified Clavien system. Univariate and multivariate analyses were conducted to identify risk factors affecting the complication rates. RESULTS: The patient cohort included 1,212 males and 714 females with a mean age of 47.8 ± 14.3 years (range 15-86). The success rate was 95.7%. The overall complication rate was 9.3%. Univariate analysis revealed that solitary kidney, stone burden, bilaterality, stone localization (proximal to the iliac crest) and stone impaction significantly affected the complication rates. Multivariate analysis revealed that preoperative shock wave lithotripsy treatment, stone impaction, multiplicity, proximal localization and stone burden were significant parameters affecting the occurrence of complications (relative risks of 6.5, 4.3, 3.3, 2.4 and 2.0, respectively). CONCLUSIONS: URS is a safe and minimally invasive procedure with a high success rate and low-grade, self-limiting complications. Preoperative shock wave lithotripsy treatment, stone impaction, multiplicity, proximal localization and stone burden were independent risk factors for the development of complications.

Utilization of a modified Clavien Classification System in reporting complications after ultrasound-guided percutaneous nephrostomy tube placement: comparison to standard Society of Interventional Radiology practice guidelines.

OBJECTIVE: To report our results on percutaneous nephrostomy (PCN) and classify our complications with the Standard of Practice Committee of the Society of Interventional Radiology guidelines and the modified Clavien Classification System (CCS). METHODS: Three hundred eighty-nine PCN insertions were performed in 322 patients (224 men and 98 women) at our institution. PCN insertion was performed under ultrasound for dilated pelvicalyceal system and ultrasound/fluoroscopy for nondilated system. PCN was considered successful if the catheter was drained urine spontaneously. Number of complications was registered. RESULTS: Primary successful PCN insertion was achieved in 368 of the 389 procedures (94.6%). The success rates for nondilated and dilated systems were 82.7% and 96.4%, respectively. Major complications occurred in 9.6% and minor complications in 9.9% according to the Society of Interventional Radiology. According to the modified CCS grades I, II, III, IV, and V was 9.9%, 1.2%, 6.8%, 1.2%, and 0.3%, respectively. Age, grade of the hydronephrosis, serum creatinine levels, and mean hemoglobin levels were statistically significant parameters for the occurrence of complications on univariate analysis. The nondilated system has statistically significant parameters affecting the complication rates on multivariate analysis (P = .001, odds ratio [OR] = 6.1, 95% confidence interval [CI] = 2-18.4). CONCLUSION: Percutaneous nephrostomy is a well-known procedure in the treatment of temporary or permanent drainage of an obstructed system. It is very important to define the complications related to interventions for interpretation of clinical comparisons more accurately. Modified CCS is a reproducible system to evaluate the complications.
