A comparison of pre- and post-operative outcomes in living donors undergoing transperitoneal laparoscopic nephrectomy and open nephrectomy: a retrospective single-center study

ABSTRACT BACKGROUND: Kidney transplantation is often regarded as the preferred therapy for end-stage renal disease. Several surgical procedures have been developed to reduce postoperative donor complications, while maintaining kidney quality. OBJECTIVE: This study aimed to compare the preoperative and postoperative outcomes of living kidney donors who underwent either transperitoneal laparoscopic nephrectomy or open nephrectomy. DESIGN AND SETTING: Retrospective study conducted in Istanbul, Turkey. METHODS: Fifty-five living-related kidney donors underwent nephrectomy and were retrospectively divided into two groups: 21 donors who underwent open nephrectomy (Group 1) and 34 donors who underwent transperitoneal laparoscopic nephrectomy (Group 2). RESULTS: In comparison to the donors who underwent open nephrectomy, those who underwent transperitoneal laparoscopic nephrectomy had significantly shorter postoperative hospital stays (2.3 ± 0.2 versus 3.8 ± 0.8 days, P = 0.003), duration of urinary catheterization (1.2 ± 0.8 days versus 2.0 ± 0.7 days, P = 0.0001), operating times (210 ± 27 minutes versus 185 ± 24 minutes, P = 0.02), and less blood loss (86 ml versus 142 ml, P = 0.048). There was no statistically significant difference between the two groups with regard to the estimated blood transfusion and warm ischemia time. The preoperative week, first postoperative week, and 1-month postoperative serum creatinine levels were comparable between the groups. CONCLUSIONS: Laparoscopic donor nephrectomy can be safely performed at centers with expertise in laparoscopic surgery. Laparoscopic donor nephrectomy has better outcomes than open donor nephrectomy in terms of length of hospital stay, duration of urinary catheterization, operating time, and blood loss.

A case of a high-flow priapism treated with superselective transcatheter embolization.

High-flow priapism is a rare condition characterized by prolonged and painless erection. It is defined as contusion or thrombosis of the cavernous body of the penis usually secondary to blunt trauma. Due to the rarity of the disease, there is no well-defined consensus about treatment. Conservative treatment is often applied with non-steroidal anti-inflammatory drug. We present a case of 58-year-old man with proximal partial priapism that developed secondary to blunt trauma to the penis. The patient did not benefit from non-steroidal anti-inflammatory drug therapy and then was successfully treated with selective embolization.

Exploration of fluoroquinolone-induced retinal pigment epithelium layer changes in the pathogenesis of macular degeneration.

PURPOSE: Fluoroquinolone toxicity studies in animals (cats, rabbits and mice) showed that acute retinal degenerations appear clinically related to phototoxicity. The aim of this study was to evaluate the association between the administration of oral fluoroquinolone and the onset of clinically or subclinically detectable acute retinal degeneration in humans. MATERIAL AND METHODS: This study included patients that received oral fluoroquinolone treatment (ciprofloxacin, levofloxacin or moxifloxacin) for variable systemic diseases diagnosed by the Department of Urology and Infectious Diseases (study group, n=76), and age and sex matched otherwise healthy subjects (control group, n=50). All the subjects underwent a detailed ophthalmologic examination including tests for visual acuity, intraocular pressures, color vision, photostress recovery time and contrast sensitivity measurements, central foveal thickness, subfoveal choroidal thickness, ganglion cell complex thickness and 10/2 Humphrey visual field test. Color fundus and fundus autofluorescence photographs were also obtained. Examinations and tests were repeated at 1st week and 1st month in the study group. RESULTS: There was no statistically significant difference among visual acuity, intraocular pressure, photostress recovery time, color vision, contrast sensitivity measurements, central foveal thickness, subfoveal choroidal thickness, average ganglion cell complex thickness, superior ganglion cell complex thickness, inferior ganglion cell complex thickness, focal loss volume, global loss volume, mean deviation, pattern standard deviation values in treatment group at baseline, 1st week and 1st month (p > 0.05, for the comparison of each parameters). There was not any alteration among color fundus and fundus autofluorescence photographs obtained at baseline, 1st week and 1st month in treatment group. All parameters within the study and control groups were similar throughout the study period (p > 0.05, for the comparison of each parameter). CONCLUSION: This study evaluated the association between the administration of oral fluoroquinolone and the onset of acute retinal degeneration. Preliminary results of this study showed that use of oral fluoroquinolone had no detectable impact on retinal degeneration at acute phase.

Urachal Actinomycosis Presenting with Recurrent Urinary Tract Infections in a Middle-aged Woman: A Rare Case Report.

The urachal cyst, a remnant of allantois sac during embryogenesis, is a rare condition in adulthood. Urachus is an embryologic remnant degenerating after birth. Abberrant obliteration of the urachus causes urachal abnormalities. The urachal cysts are almost always symptomatic when infected. The symptoms include fever, abdominal pain, tenderness, lower abdominal mass, nausea, vomiting, and dysuria. Ultrasonography, computerised tomography, and magnetic resonance imaging techniques may be insufficient for diagnosis. In most cases, staphylococcus species are isolated from cultures of urachal cysts. Other microorganisms such as Escherichia coli, Enterococcus faecium, Klebsiella pneumonia, and rarely actinomyces may be isolated. Actinomyces, an anaerobic gram-positive filamentous bacterium, is a rare cause of granulomatous disease. In this case report, a 56-year woman with urachal cyst infection with actinomyces is discussed according to current knowledge. Key Words: Urachal cyst, Urachus, Chronic cystitis, Actinomyces.

Did COVID-19 area change our urology practice: A retrospective analysis.

OBJECTIVE: This research aimed at evaluating the changing conditions and experiences of urological practice during the COVID-19 pandemic. METHODS: The data of all patients who were admitted to outpatient clinics at Hisar Intercontinental Hospital or the hospital's online patient portal system between March 11th and May 30th, 2020 were analyzed retrospectively. Of all patients, 545 in outpatient clinics and 25 in online portal system, (17%) were hospitalized for medical treatment, and 53 underwent surgery. There were 1032 patients admitted to Urology Clinics and 104 patients who underwent surgery in the same period of 2019. The pre-operative assessment of patients who were candidates of urological surgery included certain criteria for COVID-19. RESULTS: Of patients included in this study, the median age was 41 years (18-90). The mean hospital stay was 1 day (1-12), and the mean duration of operation was 25 min (3-250). Thirty-seven patients (69.8%) underwent general anesthesia, while only 11(20.8%) underwent combined spinal epidural anesthesia. Four patients (7.5%) required local and only one patient (1.9%) underwent sedo-analgesia. Complications were encountered in six patients (11.4%), urosepsis in two, pneumonia in one, and urinary tract infection in three patients. Compared to last year's numbers, the number of patients admitted to the hospital's outpatient clinic and that of hospitalized patients decreased by 47.2% and 49.1%, respectively. CONCLUSION: Emergent surgeries in urological practices can be performed safely under routine preoperative testing for COVID-19 and with the use of adequate protective equipment for both the surgical team and the patient.

A novel method in decision making for the diagnosis of anterior urethral stricture: using methylene blue dye.

OBJECTIVE: The use of methylene blue dye (MB) to highlight anatomical structures in urology has been well-established. Urethral stricture may extend about a centimeter beyond the abnormal area seen on urethrogram. Although the current literature suggests a tension-free and end- to- end anastomosis after excision of the strictured urethral segment with spongiofibrosis and surrounding corpus spongiosum in short bulbar strictures, some centers dealing with urethroplasty prefer anastomosis for short bulbar strictures while others prefer augmentation. With this study, use of MB for delineating stricture line and assessing spongiofibrosis in the diagnosis of urethral stricture was evaluated. MATERIAL AND METHODS: Five cc MB including 10 mg/mL is diluted with 10 cc saline. In the first scenario, MB is gently injected into urethra via the meatus before the urethroplasty procedure. Meanwhile, the extent of urethral segment stained by MB is noted. In the second scenario (MB spongiosography) in short bulbar stricture, insulin needles are inserted in spongiosa of the stricture site distally and proximally. MB is gently injected with distal needle. The two remaining needles are then observed. Presence of MB efflux in proximal needle implies deficiency of significant spongiofibrosis, so buccal augmentation is performed. Absence of efflux of MB implies significant spongiofibrosis and anastomotik site excised. RESULTS: Four hundred and ninety-two consecutive cases prospectively evaluated between 2010 and 2014. Precise staining of stricture was successfully observed in 464 (94%) patients. Grossly normal appearing urothelium remained pink. Histopathology confirmed that the stained urethra had a stricture. Of the 22 short bulbar idiopathic strictures, in 18 (82%) MB was seen across the stricture and urethral transection was avoided. Anastomosis was performed in 4 (18%) cases where no MB went across the primary excision. There were no known allergic complications. CONCLUSION: MB aids in delineating the urethral lumen and exact site of stricture that needs augmentation. MB Spongiography in short bulbar strictures could be used as a beneficial guide in relation to the type of urethral repair to be performed in terms of augmentation versus excision and anastomosis.

Effects of Benign Prostate Hyperplasia on Allografts in Kidney Transplant.

OBJECTIVES: Benign prostate hyperplasia is frequently diagnosed in elderly chronic renal failure patients. Although it is asymptomatic because urine flow declines in those with chronic renal failure, it may become symptomatic when urine flow increases after renal transplant. Untreated benign prostate hyperplasia may lead to several complications that adversely affect the kidney allograft. MATERIALS AND METHODS: Our retrospective study investigated data from 286 male transplant patients. Data obtained included medical history, clinical examination, prostate-specific antigen, prostate volume, and residual urine volume results. Patients had completed an International Prostate Symptom Score questionnaire to assess the low urinary symptoms. Creatinine level, residual urine volume, International Prostate Symptom Score, and uroflow-metry results were reviewed. RESULTS: The average age of patients in our group was 54.8 years. Seven patients were diagnosed with benign prostate hyperplasia, and transurethral resection of the prostate was performed. The average creatinine levels before and after transurethral resection were 2.53 ± 0.76 mg/dL and 1.66 ± 1.12 mg/dL, respectively. Creatinine levels measured 6 months after transurethral resection versus before resection were statistically significant (P < .018). Furthermore, there was a statistically significant difference (P < .017) in the postmicturition residual urine volume between the preoperative and postoperative values, which were 132.14 ± 19.33 and 47.6 ± 18.6 mL, respectively. Maximum urine flow rates before and after transurethral resection were also significantly different (P < .017). CONCLUSIONS: Although the main reasons for graft function loss after renal transplant are rejection and infections, obstructive pathologies should also be considered. Especially for elderly patients, anamnesis, uroflowmetry, and digital rectal examination play critical roles in the evaluation of benign prostate hyperplasia before and after transplant.

Approach to bulbar urethral strictures: Which technique and when?

Bulbar urethra is the most common site of anterior urethral stricture and this stricture develops secondary to idiopathic (40%), iatrogenic (35%), inflammatory (10%), and traumatic (15%) causes. Various techniques and approaches with buccal mucosal graft have been described. We wanted to describe different techniques of repair with specific advantages.

The effectiveness of extra-scrotal fixation following manual detorsion for testicular torsion: a pilot study in a rabbit model.

INTRODUCTION: To investigate the effectiveness of manual detorsion (MD) and applicability of extra-scrotal fixation for testicular torsion in a rabbit model. MATERIAL AND METHODS: Twelve New Zealand male rabbits were randomized into six groups of two rabbits each. A single-side testicular torsion (TT) model (different degrees, time and sides) was performed in all groups except the Sham group. The groups included: Group 1 (180°; 4 h), Group 2 (720°; 6 h), Group 3 (1080°; 9 h), Group 4 (540°; 1 h), Group 5 (900°; 2 h), and Group 6 (sham-only). Testes were examined by another urologist and radiologist with Color Doppler Ultrasonography (CDU). MD was performed with CDU until blood flow was observed in the affected testis. Extra-scrotal fixation was then conducted in these animals. The testes were then harvested for blinded histopathological examinations. RESULTS: TT was detected in all animals except the control group. The CDU examination detected decreased blood flow only in Group 1. An opposite rate was observed between the spermatic cord diameter and torsion degree. A wrong direction of MD in the first step was observed in two rabbits in Groups 4 and 5. Torsion signs were observed only in Group 3. Rest torsion was observed in Groups 3 and 5 after extra-scrotal fixation. Histopathological examinations showed that testicular damage increased in parallel to torsion duration. CONCLUSIONS: Extra-scrotal fixation after MD along with CDU may be a simple and minimally invasive treatment option in TT therapy. However, this must be verified with further studies.

Retroperitoneal Ancient Schwannoma: A Case Report.

Schwannomas are extremely rare tumors that are composed of Schwann cells. Retroperitoneal localization comprises 0.7% to 2.6% of all schwannomas. Patients usually present with nonspecific symptoms. There are no pathognomonic features on radiologic evaluation. Preoperative biopsy is not recommended because of complication risks; however, surgery is necessary for diagnosis and treatment. Although most schwannomas are benign tumors, those that are associated with von Recklinghausen disease are malignant. Schwannomas exhibit regions of high and low cellularity, termed Antoni A and Antoni B areas, with a diffuse positivity of S100 protein on pathologic evaluation. If there are degenerative changes, such as cyst formation, hemorrhage, calcification, and hyalinization, these tumors are termed ancient schwannomas. We present a case of retroperitoneal ancient schwannoma.

Does resectoscope size play a role in formation of urethral stricture following transurethral prostate resection?

BACKGROUND AND AIMS: To investigate the possible effect of resectoscope size on urethral stricture rate after monopolar TURP. MATERIALS AND METHODS: A retrospective study of 71 men undergoing TURP was conducted at two centers' from November 2009 to May 2013. The patients were divided into one of two groups according to the resectoscope diameter used for TURP. Resectoscope diameter was 24 F in group 1 (n=35) or 26 F in group 2 (n=36). Urethral catheter type, catheter removal time and energy type were kept constant for all patients. Urethral stricture formation in different localizations after TURP was compared between groups. RESULTS: There was no significant difference between the two groups in terms of age, pre-operative prostate gland volume (PV), prostate-specific antigen (PSA), maximal urinary flow rates (Qmax), International Prostate Symptom Score (IPSS) and post-voiding residual urine volume (PVR). The resection time and weight of resected prostate tissue were similar for both groups (p>0.05). A statistically significant higher incidence of bulbar stricture was detected in group 2 compared to group 1 (p=0.018). CONCLUSIONS: The use of small-diameter resectoscope shafts may cause a reduction in the incidence of uretral strictures in relation to urethral friction and mucosal damage.

Comparison of long-term efficacy of desmopressin lyophilisate and enuretic alarm for monosymptomatic enuresis and assessment of predictive factors for success: a randomized prospective trial.

PURPOSE: We compared the long-term success of desmopressin sublingual lyophilisate formulation and enuretic alarm therapy in children with primary monosymptomatic nocturnal enuresis, and determined predictive factors for treatment success. MATERIALS AND METHODS: A total of 142 children with primary monosymptomatic nocturnal enuresis were randomized to receive treatment consisting of desmopressin or enuretic alarm for 6 months. Treatment compliance and response were reviewed monthly in each patient using a 30-day bed-wetting diary. Outcomes were assessed according to International Children's Continence Society criteria, and success rates at 6 and 12 months were compared for desmopressin and enuretic alarm. Additional intention to treat analyses were performed, considering cases with missing data as failures. Possible demographic factors predicting success were investigated by logistic regression analysis. RESULTS: Overall 4 children (5.2%) in the desmopressin group and 20 (30.7%) in the enuretic alarm group withdrew after randomization. Based on patients who completed 6 months of treatment, success (more than 90% reduction in wet nights per month) was achieved in 76.8% and 61.8% of children in the desmopressin and enuretic alarm groups, respectively. At 12 months 77.8% of those receiving desmopressin and 75% of those treated with enuretic alarm had success. However, long-term success rate was significantly higher with desmopressin (68.8% vs 46.2%) if intention to treat population was considered. Multivariate analysis revealed treatment group, severity of enuresis and monthly income as independent predictors of cure at 6 months. CONCLUSIONS: In compliant patients desmopressin lyophilisate and enuretic alarm provided equivalent success at the end of treatment and after extended followup. Alarm therapy had a high rate of early withdrawal from therapy and consequently lower rates of success on intention to treat analyses. Severe enuresis (more than 5 wet nights weekly) is an important predictive factor for cure after first-line treatment.

Is sexual function in female partners of men with premature ejaculation compromised?

The authors enrolled 32 female partners of sexually active men with premature ejaculation to investigate their sexual functions. An age-matched sample of the same number women whose partners had no sexual dysfunction was also included. Premature ejaculation was defined for all participants as ejaculation that nearly always occurs before or within 2 min of vaginal penetration. An invitation letter was given to men with premature ejaculation to ask whether their female partners could be contacted about completing a questionnaire to measure female sexual status. On the basis of the Female Sexual Function Index, the average sexual function score was significantly lower in partners of men with premature ejaculation (21.8 ± 7.6) compared with that in healthy controls (25.9 ± 6.6). Female sexual dysfunction was diagnosed in 78% of women who has a male partner with premature ejaculation, while 40% of female partner of healthy men. All of the domain scores of Female Sexual Function Index, except the desire and pain levels, were significantly lower in female partners of men with premature ejaculation group than those of healthy subjects.

Does structured withdrawal of desmopressin improve relapse rates in patients with monosymptomatic enuresis?

PURPOSE: Relapse after cessation of desmopressin is an important problem in treating patients with enuresis. Structured withdrawal of desmopressin tablets has been shown to decrease relapse rates. However, scientific data are lacking on the structured withdrawal of the fast melting oral formulation of desmopressin. We compared relapse rates of structured withdrawal using placebo and direct cessation in a population of patients with enuresis who were desmopressin responders. MATERIALS AND METHODS: Patients diagnosed with enuresis and responding to desmopressin from 13 different centers were involved in the study. Patients were randomized into 4 groups. Two different structured withdrawal strategies were compared to placebo and direct withdrawal. Sample size was estimated as 240 (60 patients in each group), with a power of 0.80 and an effect size of 30%. Randomization was performed using NCSS statistical software (NCSS, Kaysville, Utah) from a single center. The relapse rates of the groups were compared using chi-square testing. Logistic regression analysis was performed to define the independent factors having an effect on relapse rates. RESULTS: Desmopressin treatment was initiated in 421 patients, and 259 patients were eligible for randomization. Relapse rates were 39 (1%) and 42 (4%) for the structured withdrawal groups, which were significantly less than for direct withdrawal (55, 3%) and placebo (53, 1%). Logistic regression analysis revealed that initial effective dose of 240 µcg, greater number of wet nights before treatment and nonstructured withdrawal were associated with higher relapse rates. CONCLUSIONS: We found that structured withdrawal with the fast melting oral formulation of desmopressin results in decreased relapse rates. Application of a structured withdrawal program was also an independent factor associated with reduced relapse rates, together with lower initial effective dose and number of wet nights per week. Relapse after cessation of desmopressin is an important problem, and in this study structured withdrawal was observed to be associated with decreased relapse rates compared to placebo and direct withdrawal.

The effect of rosuvastatin and atorvastatin on erectile dysfunction in hypercholesterolaemic patients.

BACKGROUND AND AIM: The aim of this study was to evaluate the effect of atorvastatin and rosuvastatin on erectile dysfunction in hypercholesterolaemic patients. METHODS: Ninety consecutive male hypercholesterolaemic patients (mean age 50.4 ± 7.9 years) who were otherwise healthy were included into the study prospectively. None of the patients had any cardiovascular risk factors except hypercholesterolaemia.The patients were divided into two groups. One group received atorvastatin while the other group was given rosuvastatin. All patients were followed for six months and International Index of Erectile Function-5 (IIEF-5) score and blood samples were re-evaluated. RESULTS: Patients were in similar ages in both groups. There were also no statistical differences in terms of blood glucose levels, total cholesterol, low density lipoprotein, high density lipoprotein, triglyceride and mean IIEF score in both groups at the beginning. After six months, no IIEF score changes were observed in the rosuvastatin group after the medication. However, the IIEF score was significantly lower in the atorvastatin group (p = 0.019). CONCLUSIONS: Rosuvastatin showed no effect on erectile dysfunction, while we observed increased erectile dysfunction with atorvastatin. Our study reveals that different statin types may have different effects on erectile dysfunction.

The role of pre-operative androgen stimulation in hypospadias surgery.

The hormonal stimulation for the purpose of penile enlargement before the hypospadias repair has been commonly used, but rarely reported. In addition to functional outcome, dihydrotestosterone (DHT) pretreatment has been suggested to improve cosmetic outcome in a preliminary randomized study. Since the randomized and controlled clinical trials on this topic are insufficient, the hormonal agent, the route of administration, dosing schedule, and the timing of treatment has been remained controversial. In order to confirm the efficiency of hormonal treatment, further well designed randomized studies with a larger number of patients and a placebo group are warranted.

Plasmakinetic vaporization versus transurethral resection of the prostate: Six-year results.

OBJECTIVE: Benign prostate hyperplasia (BPH) is becoming more prevalent in parallel to the changing demographic structures of the community. Transurethral resection is still considered the most effective treatment. Due to advances in technology, different treatment modalities are being attempted. In our study, we compared the long-term results of standard transurethral resection of prostate (TURP) with plasmakinetic vaporization of prostate (PKVP, Gyrus Medical Ltd., Bucks, UK). MATERIAL AND METHODS: Of the 75 patients who were admitted to our outpatient clinic between 2001 and 2003 with lower urinary tract complaints and who were randomized into two groups (transurethral resection (TUR) and PKVP), 36 were enrolled to study and completed a follow-up period of 72 months. RESULTS: Both groups were equal in terms of age and preoperative parameters. The preoperative maximum uroflow rate (Qmax) in the PKVP group was 6 (2.3) mL/s and the rates were 21.8 (3.4) and 20.1 (3.1) during the control visits at 36 and 72 months, respectively. For the PKVP group, these rates were 6 (3.1), 14.4 (2.6), and 15.6 (2.8), respectively. In terms of the international prostate symptom score (IPSS), for the TUR group, these values were 22 (3.8), 5.7 (1.2), and 7.9 (2.6). For the PKVP group, the respective values were 21 (3.4), 7.6 (1.4), and 11 (2.4). The IPSS and Qmax values measured at the 36(th) and 72(nd) months for both groups were significantly different from each other (p<0.05). CONCLUSION: Compared to standard TURP, PKVP was found to be unsuccessful in the treatment of BPH when long-term outcomes were considered.

Bilateral ureteral stones and spontaneous perirenal hematoma in a patient with chronic idiopathic thrombocytopenic purpura.

Idiopathic thrombocytopenic purpura (ITP) is an immune thrombocytopenia with a usually benign clinical course. Bleedings are mostly of the mucocutaneous type with mild symptoms. Massive bleedings requiring transfusion are rarely seen, unless the number of platelets decreases to extremely low levels. In this case, bilateral perirenal hematoma and bilateral distal ureteral stones were detected on a non-contrast computed tomography scan of a 57-year-old male patient who developed macroscopic hematuria during his treatment in the clinics of internal medicine because of left flank pain and diffuse petechial rashes all over his body. The patient, who had been receiving chronic ITP treatment for 1 year, had a very low platelet count (4,000/mm(3)). The patient was prescribed bed rest, and his platelet count increased to a safe level for surgical intervention of above 50,000/mm(3) with administration of prednisolone, intravenous immune globulin, and platelet suspension. A stone-free state was achieved after bilateral ureterorenoscopy and pneumatic lithotripsy. A conservative approach was followed for the perirenal hematoma. Upon regression of the perirenal hematoma, the patient was discharged at 9 weeks postoperatively.
