RESUMEN

INTRODUCTION: Refractory overactive bladder (OAB) in children can be treated with second line modalities such as as biofeedback, transcutaneous electrical stimulation (TENS), and botulinum toxin. In this study, we aimed to investigate the efficacy of biofeedback-assisted pelvic floor muscle therapy (PFMT) on symptoms, bladder capacity, uroflowmetry, and pelvic floor muscle activity (PFMA) in children with resistant OAB or dysfunctional voiding (DV) with associated seconder bladder overactivity (DV/SBO). MATERIALS AND METHODS: A total of 24 children with resistant OAB were included in the study. Patients were divided into two groups as: group-1 pure OAB and group-2 DV/SBO. Children were evaluated with voiding diary, uroflowmetry-EMG, PFMA before and after treatment. All patients were treated with PFMT. RESULTS: Urgency cured or improved in 12 of 17 (71%) of children in group-1 and in six of seven (86%) children in group-2 (P < 0.0001 and 0.031, respectively). Other symptoms cured or improved with 64%-100% recovery rates in group-1 and 50%-80% in group-2. Maximum voided volume (maxVV) in voiding diary increased from 81.6 to 150.9 mL in group-1 and from 115.6 to 175.7 mL in group-2 (P < 0.0001 and 0.063, respectively). Mean work value of PFMA increased and mean rest value of PFMA decreased significantly (P < 0.0001, 0.018 and P = 0.002 and 0.018, respectively). CONCLUSION: The measurement of PFMA in children with refractory OAB or DV/SBO gives information on the strength and endurance of PFMs. In children with refractory OAB or DV/SBO, biofeedback-assisted PFMT provides symptomatic improvement and increases functional bladder capacity.

RESUMEN

PURPOSE: Aging in men is characterized by a moderate decrease in plasma testosterone (T) levels. However, the association between partial androgen deficiency of the aging male and clinical symptoms and the ideal screening test are controversial. In this study, we investigated the association between the androgen levels and erectile function, cognitive functions and hypogonadism symptoms in aging males. MATERIALS AND METHODS: We investigated the association between total (TT), calculated free (FT) and bioavailable (BT) testosterone, and various clinical and laboratory parameters in 103 healthy males, 50-80 years old. Biochemical assessment was done after overnight fasting. Questionnaires were used to test for hypogonadism symptoms, erectile and cognitive functions. RESULTS: TT levels were not correlated with aging in this study. However, FT and BT were found to decrease with age due to rising sex hormone binding globulin. TT levels were strongly correlated with FT and BT levels (respectively p = 0.0001, p = 0.0001). TT, FT and BT were only correlated with cognitive functions (p = 0.012, p = 0.004, p = 0.02 respectively). There was no correlation between TT, FT and BT levels and erectile function and hypogonadism symptoms. CONCLUSION: T values in our study sample did not correlate with clinical signs and symptoms of hypogonadism. Thus, according to our data, symptoms in the aging male should not be indiscriminately assigned to a decrease in TT, FT or BT levels.

RESUMEN

AIMS: To examine whether obstruction changes the expression of prostaglandins (PGs) in bladder, intravesical low-dose aspirin could be used as a new route of drug administration, this way of administration influences PGs' expression, and contractile function of the bladder is protected after treatment. METHODS: Eighteen rabbits were divided into three groups. Sham-operated group (group 1) included 6 rabbits. Twelve rabbits were partially obstructed for 70 days. Six of these 12 rabbits not receiving any treatment constituted obstructed group (group 2). The remaining six rabbits received 2 mg/kg/day aspirin (group 3). One rabbit in each group was evaluated on 1st, 7th, 14th, 28th, 42nd, and 70th days following obstructive surgery. After scarification, the percentage of collagenous area and concentrations of PGE2 and PGF2-alpha were measured. Contractile responses to field stimulation (EFS), carbachol, and potassium chloride (KCl) were determined. RESULTS: Wet tissue PGE2 and PGF2-alpha levels were higher in obstructed group than the other groups. Aspirin decreased the percentage of collagenous area in group 3 compared to the group 2, but this difference was not statistically significant. The strips from aspirin groups resulted in better contractile response to cholinergic stimulation with KCl, but this difference was not statistically significant between the obstructed and aspirin groups. Similarly, carbachol did not elicit significantly greater concentration-dependent contraction in strips from obstructed group compared to those from aspirin groups. Maximum responses to EFS were not significant in aspirin group compared to those from obstructed group. CONCLUSIONS: Intravesical aspirin may have protective effect on partially obstructed bladder.

RESUMEN

AIMS: We retrospectively review patients who underwent ureteral implantation with a psoas hitch during obstetric or gynecologic operations and describe a new modification. METHODS: Between December 1997 and May 2005, 20 patients between 26 and 56 years underwent ureteral reimplantation by using the nonrefluxing, extravesical Lich-Gregoir onlay technique with psoas hitch at our institution by the same reconstructive surgery team. Additionally, we used a urethral catheter balloon as a landmark for the bladder mucosa and fixed the bladder to the psoas tendon by using the balloon. We performed 14 ureteral reimplantations during the surgery as intraoperative reconstruction. In 6 patients, delayed reconstruction of the ureter was performed a few days following the previous operation. RESULTS: For intraoperative and delayed reconstructions, the mean operation time for ureteral reimplantation was 24 and 75 min. We took out the urethral catheter on the second operative day and the anastomotic drain on the third. The average hospital stay was 5.7 days. No cases of chronic flank pain, recurrent pyelonephritis, persistent severe hydronephrosis or compromised renal function occurred. No patient required reoperation. CONCLUSIONS: Modified psoas hitch ureteral reimplantation is an effective and safe way of reconstruction for treating defects in ureteral length.

RESUMEN

Nephrolithiasis management within an ectopic kidney presents a challenge to the urologists. Several treatment modalities are possible in this group of patients. Although percutaneous nephrolithotomy (PNL) is an accepted treatment modality in anatomically normal kidneys, ectopic pelvic kidneys require a different and more complicated approach for PNL. We recently treated a 24-year-old patient with calculus and an encrusted J-J stent fragment in pelvic ectopic kidney with a previous history of open pyelolithotomy. Laparoscopy-assisted tubeless percutaneous nephrolithotomy was performed. The technique and the patient characteristics are reported.

RESUMEN

OBJECTIVE: We have reviewed the data of the patients in order to evaluate the effectiveness of our ureterocystoplasty technique in augmentation cystoplasty operation. MATERIAL AND METHODS: Data of a total of 16 patients with bilateral functional kidneys who had undergone augmentation ureterocystoplasty between January 1995 and June 2018 which were retrieved during the retrospective archive scanning were included in the study. Ultrasonography (USG), serum blood urea nitrogen and creatinine values and Technetium-99 DTPA (Tc-99 DTPA) scan were used to evaluate the renal function of the patients. Intravenous pyelography (IVP) and USG were used to evaluate the ureters before surgery. Magnetic resonance (MR) urographies were performed in our center. RESULTS: Of the total 16 patients, 10 were male and 6 were female, while ages ranged from 1 to 24 years. Among 16 patients, the most common cause of neurogenic bladder etiology was meningomyelocele. In the urodynamic studies performed before the operation, it was determined that the bladder capacities of the patients were between 40-180 mL and the bladder compliances were 1.0-4.0 cc/cmH2O. At postoperative 3rd months, it was determined that the bladder capacities of the patients were between 180-330 mL and the bladder compliances were between 6.0-24.0 cc/cmH2O. CONCLUSION: Augmentation ureterocystoplasty seems to be an appropriate technique in which successful results are obtained with appropriate patient selection. Besides, complications that may occur due to use of ileal segment are avoided.

RESUMEN

PURPOSE: Several animal and human studies in vivo and in vitro indicate that testosterone has vasodilatory effects on different vessels. However, the effect of testosterone on the internal spermatic vein is not clear. In addition, the role of testosterone in the pathophysiology of varicocele is not established. We investigated the effect of testosterone on the internal spermatic vein in vitro in patients with varicocele and analyzed its relation to varicocele grade. MATERIALS AND METHODS: Isolated internal spermatic veins were collected from patients who underwent varicocelectomy and orchiectomy. The preparations (3 to 4 mm rings) were mounted in an organ bath containing 10 ml Krebs-Henseleit solution on an L-shaped brace for tension measurement along the former circumferential axis. Changes in venous tension in the presence of testosterone (0.1 to 300 microM) were recorded isometrically by a force displacement transducer. RESULTS: Cumulative concentrations of testosterone (0.1 to 300 microM) elicited concentration dependent relaxation of 45 mM KCl induced active tone in the internal spermatic vein (mean +/- SEM 60.97% +/- 5.05% of the KCl induced contraction). Relaxation to testosterone (1 to 300 microM) was significantly higher in 5 cases of grades 0 and 1 varicocele than in 15 of grades 2 and 3 varicocele (maximum relaxation response 78.58% +/- 8.25% vs 55.10% +/- 5.3% of the KCl induced contraction). CONCLUSIONS: To our knowledge the current report is the first to describe testosterone induced relaxation of the human internal spermatic vein. The vasodilatory effect of testosterone on the human internal spermatic vein decreases in high grade varicoceles.

RESUMEN

BACKGROUND AND PURPOSE: Data concerning extracorporeal shock wave lithotripsy (SWL) management of small (< or = 5 mm) asymptomatic renal caliceal stones are lacking in the literature. In this study, we aimed to determine the effectiveness of SWL in a special group of patients who had very small (< or = 5 mm) asymptomatic renal caliceal stones. The group of patients consisted of pilots, gendarmes, and soldiers, such as commandos, for whom treatment was obligatory and who had to be stone free because of their military duties. PATIENTS AND METHODS: We retrospectively examined SWL data and retrieved information for 84 patients with small asymptomatic renal caliceal stones. The SWL sessions were performed with a Siemens Lithostar lithotriptor. The mean age of the patients was 34 +/- 13 years. The mean stone size was 4.8 +/- 0.4 mm. The mean numbers of shockwaves and energy used were 2707 +/- 1742 and 18 +/- 2 kV, respectively. The location of stones were: 11 right upper calix, 10 right middle calix, 17 right lower calix, 13 left upper calix, 16 left middle calyx, and 17 left lower calix. Eighty-four patients underwent 101 SWL sessions. Only eight patients had second and three patients had third SWL treatments. SWL was performed five times for only one patient. All mean values were realized with an SPSS 10.0 statistical program. RESULTS: After the first, second, and third SWL sessions, the stone-free rate was calculated as 87%, 93% and 94%, respectively. Only five patients with lower renal caliceal stones were not stone free. The reported complications were macroscopic hematuria necessitating medical attention in four patients, skin ecchymosis in seven patients, severe colic pain in two patients, and urinary-tract infection in one patient. There was no need for hospitalization for these complications. CONCLUSION: SWL is effective and safe in patients with very small (< or = 5 mm) asymptomatic renal caliceal stones in all locations.

RESUMEN

Splenogonadal fusion (SGF) is a rare congenital anomaly in boys and girls. It commonly presents as a testicular mass treated with an unnecessary orchiectomy. We present 3 cases of SGF diagnosed in adulthood and discuss the published literature focusing on several aspects of this rarity. These cases of SGF of both types presented with the usual complaints. In our first case, orchiectomy was performed since the left testis was hypoplastic and testicular neoplasm could not be ruled out. The testicles could be preserved in the latter 2 cases. The second case is the continuous-type SGF associated with contralateral testicular aplasia and, to our knowledge, this is the first reported case of continuous SGF associated with testicular aplasia. Knowledge of this entity may help prevent unnecessary orchiectomy.

RESUMEN

Inverted papilloma (IP) of the urothelium accounts for 2.2% of urothelial neoplasms. The aim of this study was to report the results of 13 patients with urinary IP, pointing out the clinical features, presentations, treatment options and outcomes. The mean age and mean follow-up periods of the patients were 60.23 +/- 3.25 (range, 44-81) years and 30 (range, 6-42) months, respectively. There was no coexistence of urothelial carcinoma with IP at presentation. Cystoscopy showed a solitary papillary tumor in the bladders of 11 patients and solid pedunculated tumors in the remaining two patients. The site of development was the bladder in 12 cases (92%) and ureter in one (8%) case. Transurethral bladder tumor resection was performed in 12 cases. For the case with IP in the ureter, nephroureterectomy was performed. Pathologic examination demonstrated that seven of the 13 cases were of the trabecular type and six were of the glandular type. Of the 13 cases, two (7%) had recurrence, at 1 year and 1 month and 1 year and 5 months from initial resection. The male to female ratio was 5.5:1. Initial symptoms included macroscopic hematuria in five cases, microscopic hematuria in four, and dysuria and microscopic hematuria in three; one case was asymptomatic. IPs of the urinary bladder are benign tumors that can be treated successfully by transurethral resection and fulguration of the tumor bed. In addition, these lesions must be followed up closely for recurrence and malignant transformation.

RESUMEN

The approach for the intravesical suspicious lesions or stones in the preadolescent children especially in boys is still a challenging problem. Open surgery, percutaneous suprapubic endoscopy or transurethral endoscopic approaches are the treatments of choice in children. However, there is a group in children between the ages of 10 and 12 years, which can be named as grey zone population; the length of the instruments is insufficient for transurethral intervention such as endoscopic stone extraction, transurethral bladder tumor resection especially for the lesion at the posterior bladder wall in this group. The aim of this study is to describe a new technique using laparoscopic instruments for percutaneous bladder stone and tumoral lesion and determines the efficacy of this procedure. Satisfactory results have been obtained in patients with these pathologies. In selected cases, operation time, urethral and mucosal damage, hospital stay, and cost can be decreased to a minimum with this simple technique.

RESUMEN

BACKGROUND: The aim of this study was to determine the duration that antibiotherapy should have in order to make total prostate-specific antigen (tPSA) levels decrease to normal ranges in patients without prostatitis symptoms but with total PSA levels around 4.01-9.9 ng/dL. METHODS: A total of 129 male patients were enrolled and divided into either study group (N.=102) or control group (N.=27). The study group received a 21-day treatment with ofloxacin 400 mg/day, while the control group did not receive any treatment. tPSA and free PSA levels were measured on the 7th, 14th and 21st day, and at the 3rd, 6th, and 12th month of the study. tPSA levels and the number of patients whose tPSA levels decreased ≤4.0 ng/dL levels was recorded and analyzed for statistical significance. RESULTS: At 7, 14, and 21 days mean tPSA values were all lower than baseline values and the differences were statistically significant (P<0.05). Of 102 patients 31, 38 and 36 patients had decreased tPSA levels at 7, 14, and 21 days, respectively. But when we compared 7th day mean tPSA levels with days 14 and 21, we found no statistical differences (P>0.05). Sixty-six patients had persistently high tPSA levels and 64 of them underwent prostate biopsy. Prostate cancer was detected in 8 of them (12.5%). CONCLUSIONS: A seven-day course of antibiotherapy is enough to normalize PSA levels in gray-zone patients. If recurrence of PSA increase is seen during follow-up, antibiotherapy can be useful again in those patients who previously benefited from it, while it will prove unnecessary in those who did not have their tPSA level normalized by it.

RESUMEN

Imaging the urinary tract in children has been mainly based on ultrasound (US) and intravenous pyelography (IVP), but these imaging modalities rarely show ectopic insertion of the ureter and the condition is often under diagnosed due to unusual clinical presentations. Recently newer magnetic resonance urography sequences have been developed that provide better delineation of the urinary tract. We report a 3-year-old girl presenting continuous dribbling of urine in which magnetic resonance urography revealed ectopic vaginal insertion of the ureter.

RESUMEN

The inguinal approach is used for the treatment of hydrocele in the pediatric population. Although studies on scrotal orchiopexy have mentioned hernia or hydrocele repair through the same scrotal incision as a part of an orchiopexy procedure, there are a few studies reporting the treatment of isolated communicating hydrocele through a scrotal incision. We retrospectively evaluated and compared the outcomes of inguinal and scrotal approaches for the treatment of communicating hydrocele in boys. The classical inguinal and scrotal approaches to the treatment of communicating hydrocele were performed on 46 and 30 testicular units (in 43 boys and 27 boys, respectively). The patients' charts were reviewed to assess the operative times as well as the immediate and long-term complications during follow-up periods. The patients' ages ranged from 1 year to 8 years (3.6 ± 2.0 years) in the inguinal group and from 1 year to 10 years (mean 4.6 ± 2.8 years) in the scrotal group. Operative time was significantly lower in the scrotal group (p < 0.0001). The early minor complication rate did not differ between the two groups. Furthermore, there were no major complications noted. None of the patients had hydrocele recurrence after a mean follow-up of 6 months. The advantages of the scrotal approach for the treatment of communicating hydrocele are as follows: it is well tolerated, simple, and cosmetically appealing, and it has a short operative time in comparison with the standard inguinal approach. The scrotal incision technique is an effective alternative in communicating hydrocele treatment.

RESUMEN

We evaluated the effectiveness of pulsed radiofrequency (PRF) denervation of spermatic cord for the treatment of chronic orchialgia. Five patients diagnosed with chronic orchialgia were evaluated with a thorough medical and psychiatric history, physical examination, and scrotal Doppler ultrasound, urinary system x-ray film, and urine analyses. One of the patients had bilateral chronic orchialgia. All of the patients had pain for a period of at least 3 months, and multiple conservative therapies failed to alleviate the pain. The patients, who had temporary pain relief after undergoing outpatient diagnostic cord block, were determined to be candidates for PRF denervation. PRF denervation of spermatic cord was performed for 6 testicular units. Visual analog scores were noted before and after the procedure. There were no pathologic conditions that indicated chronic orchialgia in any of the patients. No complications, including testicular atrophy or hypoesthesia of the scrotal or penile skin, occurred after the procedure. Mean visual analog scores before and after the procedure were 9 and 1, respectively. None of the patients needed any analgesics after the procedure or during the follow-up period. Mean follow-up period was 20 ± 2.5 weeks. No recurrence was noted, and none of the patients needed additional therapy. This is a limited case report on the short-term use of PRF. Randomized, placebo-controlled, and long follow-up period studies are needed to better assess the efficacy of this procedure for chronic orchalgia.

RESUMEN

PURPOSE: The main objectives of this retrospective cohort study were to evaluate reproductive endocrine and semen profiles before and after simple orchiectomy in patients with unilateral postpubertal cryptorchidism and to investigate the relationship between hormone levels and histopathology of the removed testis. METHODS: We evaluated 40 adult males who were admitted to our clinic, between 2001 and 2007, with unilateral undescended testis. Right orchiectomy was performed in 27 patients and left orchiectomy in 13. Semen analysis, serum inhibin B, follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone levels were examined in before and 3 months after orchiectomy. Orchiectomy materials were evaluated histopathologically. RESULTS: Semen parameters, as well as testosterone and LH levels, did not change in any histopathological subgroups in the postoperative follow-up. In patients with maturation arrest, mean serum inhibin B level statistically significantly decreased from 160.9 to 83.5 pg/ml, and mean FSH level significantly increased from 4.8 to 7.6 mIU/ml after orchiectomy (p value, 0.008 and 0.008, respectively). Though, the levels were still within the normal range of the two hormones. CONCLUSIONS: Simple orchiectomy does not have any effect on semen parameters and testosterone level in patients with postpubertal cryptorchidism. The change in inhibin B and FSH levels after orchiectomy in patients with maturation arrest is not clinically significant.

RESUMEN

PURPOSE: Systemic chemotherapy regimens with cisplatinum have been associated with several toxicities. Thus, a loco-regional therapy approach may greatly reduce the toxicity. For this purpose, we designed this experimental study to investigate whether local chemotherapeutic injection is superior to systemic cisplatinum injection for retroperitoneal lymph nodes. METHODS: A total of 48 male Wistar rats were included to the study. Rats were divided into six groups. In the first three groups, systemic applications of cisplatinum, carboplatinum and oxaliplatin were performed, respectively. In the last three, local administration of cisplatinum, carboplatinum and oxaliplatin was performed, respectively. One hour after the chemotherapeutic agent applications, retroperitoneal lymph nodes were dissected and platinum concentrations were analyzed. RESULTS: When compared with systemic route, achieving higher platinum concentrations in the local chemotherapeutic application groups was the most spectacular result of the study. Serum platinum concentrations were also lower in the local application groups than systemic ones. When we compared local and systemic applications between three chemotherapeutic agents, the most significant concentration difference was seen in carboplatinum group. CONCLUSION: The results of this study demonstrate that intralymphatic delivery of cisplatinum, carboplatinum and oxaliplatin leads to higher drug concentrations in the retroperitoneal lymph nodes when compared with intravenous administration.

RESUMEN

OBJECTIVES: We researched the survival of bone marrow-derived mesenchymal stem cells (MSCs) and the results of MSCs' injected into decompensated bladders in a rabbit model. METHODS: Partial bladder neck obstruction (PBNO) and subsequent decompensation of the bladder was achieved by wrapping the bladder neck with autologous rectus fascia. In the first aspect of the experiment 18 rabbits underwent MSC injection into the decompensated bladder to prove the survivability of injected MSCs. For this purpose MSCs were isolated, transfected with Green Fluorescent Protein (GFP), and injected into the detrusor layer. Once viability was assessed in the first phase, an additional 10 rabbits underwent PBNO in the second phase. Five of these animals underwent subsequent MSC injection (group 3, stem cell) and 5 did not (group 2, obstruction). Both groups were compared to 5 controls (group 1). Urodynamics were performed in all groups. After the animals were sacrificed the groups were compared via morphometric analysis, contractile response to carbachol and KCl, and muscarinic receptor type analysis. RESULTS: On morphometric analysis, collagenous area rates were 43, 53 and 37% in group 1, 2 and 3, respectively. There was no statistically significant difference between groups in terms of bladder weight, bladder capacity and vesical pressure. The contractile effects of KCl and muscarinic agonist carbachol were significantly higher in groups 1 and 3 than group 2. The response to carbachol was antagonized by muscarinic M(1) and M(3) receptor antagonist pirenzepine and abolished by muscarinic M(3) receptor antagonist 4-DAMP in all groups. CONCLUSIONS: The injection of MSCs decreased the collagenous area, increased detrusor contractility. Functional M(3) receptors were also expressed in MSCs-injected bladder smooth muscle as well as in control group.

RESUMEN

AIM: To evaluate the possible relationship between varicocele and chronic constipation. METHODS: Between April 2009 and May 2010, a total of 135 patients with varicocele or constipation and 120 healthy controls were evaluated. Patients were divided into two groups. In both groups detailed medical history was taken and all patients were examined physically by the same urologist and gastroenterologist. All of them were evaluated by color Doppler ultrasonography. All patients with constipation, except for the healthy controls of the second group, underwent a colonoscopy to identify the etiology of the constipation. In the first group, we determined the rate of chronic constipation in patients with varicocele and in the second group, the rate of varicocele in patients with chronic constipation. In both groups, the rate of the disease was compared with age-matched healthy controls. In the second group, the results of colonoscopies in the patients with chronic constipations were also evaluated. RESULTS: In the first group, mean age of the study and control groups were 22.9 ± 4.47 and 21.8 ± 7.21 years, respectively (P < 0.05). In the second group, mean age of the study and control groups were 52.8 ± 33.3 and 51.7 ± 54.3 years, respectively (P < 0.05). In the first group, chronic constipation was observed in 8 of the 69 patients with varicocele (11.6%) and 3 out of 60 in healthy controls (5%), respectively. In this regard, there was no statistical significance between varicocele patients and the healthy control (P = 0.37). In the second group, varicocele was observed in 16 of the 66 patients with chronic constipation (24.24%) and 12 out of 60 in healthy controls (20%) respectively. Similarly, there was no statistical significance between chronic constipation and healthy controls (P = 0.72). Internal/external hemorrhoids were detected in 4 of the 16 patients with chronic constipation and varicocele, in the second group. In the remaining 50 patients with chronic constipation 9 had internal/external hemorrhoids. In this regard, there was no statistical significance between chronic constipation and healthy controls (P = 0.80). CONCLUSION: Chronic constipation may not be a major predictive factor for the development of varicocele, but it may be a facilitator factor for varicocele.
