RESUMEN

We retrospectively reviewed and compared the results of corporal plication procedures for the correction of congenital penile curvature (CPC) between pre-pubertal and post-pubertal boys and find whether age matters in the success rates. We reviewed the records of 32 patients with CPC without hypospadias treated by simple plication near the 12 o'clock position between 1998 and 2018 in our clinic. Patients under 13 years of age and not had puberty yet were accepted as pre-pubertal. Residual curvature less than 10° during follow-up was accepted as a surgical success. The mean age of the pre-pubertal group was 8.3 (2-12) years, while 16.2 (14-21) for the post-pubertal patients. The mean follow-up was 38.7 (24-154) months in the pre-pubertal group and 45.1 (23-150) months in the post-pubertal group. The success rates of corporal plication in pre-pubertal and post-pubertal groups were 78% and 83% respectively (p = .753). The success rates of corporal plication were similar between pre-pubertal and post-pubertal boys. However, as the series was small further studies should be favoured to determine the effect of age on success rates.

RESUMEN

PURPOSE: To describe our new surgical technique for preserving the bladder neck during robot-assisted laparoscopic prostatectomy (RALP) and to present the anatomy between the bladder neck and prostate. METHODS: Between December 2012 and May 2014, 52 RALPs were performed at our institute. Demographic, perioperative, and postoperative data were recorded. Quality of life (QoL) scores were assessed before RALP, after urethral catheter removal, and at the first month after RALP. Fatty connective tissue between bladder neck and prostate was introduced, and circular muscle fibers of the internal sphincter were seen in all patients. Complications were classified according to the Clavien-Dindo classification. Statistical analyses were performed. RESULTS: Mean follow-up was 9.6±5.2 months; mean age was 61.1±6.5 years. Our novel surgical technique for preserving the bladder neck was performed in 52 patients, and they were continent after catheter removal; mean duration of the catheter was 9.4±1.4 days. There was a significant difference in QoL before RALP and after catheter removal, however, but there was no statistical difference between before and 1 month after RALP (respectively; P<0.001, P=0.5). Furthermore, there was no complication related to the bladder neck such as bladder neck stricture, acute/chronic urinary retention, as well as no Clavien III, IV, and V complications. In addition, conventional laparoscopy and/or open surgery was not needed in any of the RALP cases. CONCLUSION: Our novel technique provided very early continence at the time of catheter removal after RALP within short-term follow-up. This can help early recovery and develop QoL scores after RALP.

RESUMEN

BACKGROUND AND OBJECTIVES: We present our initial experience and long-term results with transperitoneal laparoscopic nephropexy with nonabsorbable polymer clips. METHODS: Seven patients aged 34 to 47 years previously diagnosed with mobile kidney presented with chronic pain refractory to analgesics and underwent a transperitoneal laparoscopic nephropexy procedure with nonabsorbable polymer clips by fixing the perirenal tissue to the transversus abdominis fascia and triangular ligament. RESULTS: Mean operation time was 20 minutes. All patients were discharged after 24 hours. Follow-up intravenous pyelogram (IVP) at 60 and 150 days showed the right kidneys in a more cephalad position, and showed pelvicaliceal dilatations and that the ureteral kinks seemed to be resolved. On days 15, 60, 90, and 150 of the first- and second-year follow-ups, severity of pain was 1 of 10 on the visual analog scale. CONCLUSION: We believe that the technique of transperitoneal laparascopic nephropexy with nonabsorbable polymer clips on patients with symptomatic mobile kidney is safe and easy to perform and shows successful long-term results.

RESUMEN

Our aim was to evaluate the risk of arteriovenous fistula (AVF) formation after en bloc stapling of the renal hilum during transperitoneal laparoscopic nephrectomies (LNs). A retrospective review of 35 laparoscopic simple or radical nephrectomies or LNs was carried out. Patients were clinically followed up for renal hilar AVF formation, which could lead to new onset diastolic hypertension, abdominal murmur, and congestive heart failure. In addition, abdominal computed tomography and arteriography were carried out to diagnose renal hilar AVF formation during 6 to 20 months' follow-up. No statistically significant differences were measured between the systolic and the diastolic blood pressures between the preoperative and the postoperative periods (P>0.005). Abdominal murmur and new-onset congestive heart failure were not detected in any of the patients on physical examination. Our results suggest that en bloc stapling of the renal hilum during LN procedures is safe and effective.

RESUMEN

The aim of this study is to investigate the effects of dietary factors on 24-hour urine parameters in patients with idiopathic recurrent calcium oxalate stones. A total of 108 of idiopathic recurrent calcium oxalate stones were included in the study. A 24-hour urinalysis was performed and metabolic abnormalities were measured for all of the patients. All of the patients were given specialized diets for their 24-hour urine abnormalities. At the end of first month, the same parameters were examined in another 24-hour urinalysis. Hyperoxaluria, hypernatruria, and hypercalciuria were found in 84 (77%), 43 (39.8%), and 38 (35.5%) of the patients, respectively. The differences between the oxalate, sodium, volume, uric acid, and citrate parameters before and after the dietary intervention were significant (p < 0.05). The calcium parameters were not significantly different before and after the intervention. We found that oxalate, sodium, volume, uric acid, and citrate-but not calcium-abnormalities in patients with recurrent calcium oxalate stones can be corrected by diet. The metabolic profiles of idiopathic calcium oxalate stone patients should be evaluated and the appropriate dietary interventions should be implemented to decrease stone recurrence.

RESUMEN

AIM: Urinary stone disease affects people of all ages. With its satisfactory efficacy ranges in all age groups and lack of side-effects, extracorporeal shock wave lithotripsy (ESWL) has become the preferred treatment modality for uncomplicated renal and proximal calculi ≤ 20 mm. In the present study, we aimed to assess the safety and efficacy of the ESWL treatment in elderly patients. METHODS: A retrospective study was carried out on patients aged over 65 years who underwent shock wave lithotripsy at our Department from 2009 to 2011, with a Siemens Lithostar electromagnetic shockwave lithotripter. A total of 231 patients (157 males, 74 females) out of 1694 (13.6%) were studied. The patients were divided into two groups (group 1 = 65-70; group 2 >70). The effect of age and other possible predicting factors (sex, stone localization and stone size) were investigated. Concomitant diseases and related complications were also evaluated. RESULTS: An overall stone-free rate (SFR) of 82.2% was found. The influence of sex on SFR was non-significant. There was no significant difference when comparing SFR between the age groups. When patients were divided into those with renal and ureteral stones, the SFR were 94.4% and 67.6% (P < 0.01), respectively. The SFR of the stone size groups, ≤ 10 mm and > 10 mm were 80% and 84.4%, respectively. Comorbidity was present in 148 patients. Complications were noted in 56 of 231 patients. Of 56 patients, 43 had minor complications and 13 major complications. CONCLUSION: ESWL seems to be an effective first-line treatment choice for urinary stones in elderly patients with careful patient selection and personalized preparation.

RESUMEN

We modified our technique in transperitoneal laparoscopic nephrectomies and compared its results with the classical technique. Classical technique was performed in 85 cases (group 1). Modified technique (n=98) included direct kidney upper pole access and early ligation of renal pedicle (group 2). No significant differences were detected regarding mean patient age, intraoperative blood loss, and duration of hospital stay between the 2 groups (P>0.05). Mean operation time was 64.9 ± 19.3 and 28.2 ± 7.7 minutes, respectively in groups 1 and 2 (P=0.001). Mean operation time including right nephrectomies was 68.7 ± 23.4 and 24.2 ± 6.3 minutes, respectively in groups 1 and 2 (P=0.001). Mean operation time including left nephrectomies was 63.8 ± 17.1 and 33.6 ± 5.1 minutes, respectively in groups 1 and 2 (P=0.001). Similarly, mean operation time was significantly shorter in group 2 when analysis was performed among right and left radical and simple nephrectomies between the 2 groups (P=0.001). Direct upper kidney pole access and early ligation of renal pedicle seems to be significantly facilitating transperitoneal laparoscopic nephrectomy procedures.

RESUMEN

OBJECTIVES: To investigate at the molecular level, whether the combined use of an antioxidant (L-carnitine) and a selective cyclooxygenase-2 (COX-2) inhibitor (meloxicam) is effective in the treatment of cellular damage caused by testicular torsion. METHODS: A total of 30 male Wistar rats were randomly divided into 5 groups. The control group underwent a sham operation, and the second group underwent torsion/detorsion for 90 minutes. Groups 3 and 4 received L-carnitine (500 mg/kg/d) and meloxicam (3 mg/kg/d), respectively. Group 5 also received these 2 agents, in addition to the same torsion/detorsion procedure. Bilateral orchiectomy was performed 96 hours after the operation in all groups. cDNA was synthesized after isolation of total RNA from the tissues. The relative expression of interleukin (IL)-1a, COX-2, and ß-actin genes was measured by real-time polymerase chain reaction. RESULTS: The COX-2 and IL-1a mRNA levels had significantly decreased in groups 3, 4, and 5 compared with group 2 (P<.05). COX-2 and IL-1a mRNA levels were significantly great in the torsion/detorsion group (P=.007). The COX-2 and IL-1a mRNA levels significantly decreased in the torsion/detorsion testis after maximal treatment (P<.001). CONCLUSIONS: Meloxicam seems to exert its inhibitory effect on the expression of specific genes of inflammation, as well as the combination therapy. Because the effects of these inflammatory genes are still evident 4 days after detorsion, combination therapy using these agents could be administered until late postoperative period to prevent the initiation of autoimmune activity against sperm cells and protect the innocent contralateral testis from the insult of antisperm antibodies.

RESUMEN

Nephrolithiasis is a complex disease and many gene polymorphisms have been associated with stone formation. In this study we aimed to investigate another possible relationship between E-cadherin gene (CHD1) 3'-UTR C/T polymorphism and calcium oxalate nephrolithiasis in the Turkish population. Study population was composed of 143 patients with nephrolithiasis and 158 control subjects. CHD1 3'-UTR C/T polymorphism was analysed using polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) technique. Genotype distribution of the investigated polymorphism was not deviated from Hardy-Weinberg equilibrium (HWE) in patients and control subjects (P > 0.05). C allele frequency was 85.7 and 85.1% in patients and controls, respectively (P = 0.836). Genotype distributions of the CHD1 3'-UTR C/T polymorphism among patients were also not significantly different from those among control subjects (P = 0.636). Our results showed that there is no association between the CHD1 gene 3'-UTR C/T polymorphism and nephrolithiasis in our population.

RESUMEN

OBJECTIVES: To investigate the involvement of oxidative stress in the pathogenesis of acute pyelonephritis, and to evaluate the impact of meloxicam and/or L-carnitine in addition to conventional antibiotic treatment. METHODS: A total of 48 Wistar rats were divided into 4 groups according to their treatment, which was started 1 day after inoculation of all rats with Escherichia coli (ATCC 25 922, 10(10) cfu/mL). Group 1 received only antibiotic treatment with ceftriaxone (50 mg/kg, IM). Groups 2 and 3 received L-carnitine (500 mg/kg, IM) and meloxicam (3 mg/kg, IM) in addition to conventional treatment, respectively. Group 4 received combination therapy (L-carnitine and meloxicam) in addition to the first group. Rats were killed 3 and 7 days after E. coli inoculation and underwent nephrectomy. Histologic determination of tubular atrophy, acute and chronic inflammation, interstitial fibrosis and biochemical determination of superoxide dismutase and catalase activity, total thiol content, total antioxidant capacity, and malondialdehyde and protein hydroperoxide levels were measured. RESULTS: Interstitial fibrosis (P = .06), chronic inflammation (P = .536), and tubular atrophy (P = 0.094) decreased in group 4 compared with the other groups, but there was a statistically significant decrease only in acute inflammation (P = .015). In addition, if the day of nephrectomy is considered, there was again a significant decrease in acute inflammation on day 7 compared with day 3 in groups 2, 3, and 4 (P = .002). Catalase significantly increased in group 2 (P = .029), group 3 (P = .02), and group 4 (P = .014), and decreased in group 1 (P = .012) in day 7. CONCLUSIONS: L-carnitine and meloxicam alleviated oxidative stress, probably by decreasing lipid peroxidation and enforcing antioxidant defense system. Acute renal inflammatory injury can be prevented much more effectively by combination therapy rather than by conventional therapy alone.

RESUMEN

OBJECTIVES: To evaluate the association between fibronectin gene (FN1) polymorphisms and calcium oxalate nephrolithiasis as a genetic risk factor. METHODS: Genomic DNA of 143 patients with calcium oxalate nephrolithiasis and 154 healthy controls were screened for polymorphisms (HaeIII b, MspI, and HindIII) of the FN1 gene, using polymerase chain reaction-restriction fragments length polymorphism method. Allele and genotype frequencies were compared between the groups. RESULTS: Although the observed differences between distribution of genotypes of AA, AB, and BB (for HaeIII b), as well as CC, CD, and DD (MspI) were not significant, FF genotype for HindIII showed significant difference when compared with both EF and EE + EF genotype (P = .00202 and P = .00203, respectively). CONCLUSIONS: The results of our study revealed that HindIII polymorphism of the FN1 gene is highly associated with calcium oxalate stone disease. This association makes FN a good candidate for further studies about the etiology of stone disease, and in the future it could be a candidate marker for evaluating the genetic risks in patients with nephrolithiasis.

RESUMEN

Calcium oxalate (CaOx) nephrolithiasis has a complex pathogenic mechanism. Besides environmental factors, genetic factors also have influence on stone formation. This study represents the effects of heparan sulfate (HSPG2) gene polymorphism for determining the risk of urolithiasis. We investigated 143 CaOx stone formers with 158 healthy individuals for the BamHI restriction site polymorphism located in intron 6 of the HSPG gene using the polymerase chain reaction, restriction fragments length polymorphism method. After digestion with BamHI, the polymorphism was assumed to cause three genotypes according to the banding types as GG (242 bp), GT (242, 144, and 98 bp) and TT (144 and 98 bp). According to the genotype frequencies between the groups, TT genotype showed significantly increased risk for urolithiasis than TG and GG genotypes. We concluded that HSPG2 gene polymorphism might be one of the genetic factors affecting the CaOx stone formation.

RESUMEN

PURPOSE: To investigate the probable effect of lower-pole pelvicaliceal anatomy on stone clearance after shockwave lithotripsy (SWL) in patients with nonobstructive renal pelvic stones. PATIENTS AND METHODS: The clinical records of patients with isolated renal pelvic stones who underwent SWL between 1996 and 2005 were reviewed. After excluding patients with obstruction leading to dilatation, major anatomic abnormalities, noncalcium stones, metabolic abnormalities, history of recurrent stone disease, multiple stones, and previous renal surgery, 153 patients were enrolled in the study. Lower pole infundibulopelvic angle (IPA) and infundibular length and width were measured from intravenous urography. Patients were classified into three groups according to stone burden (group 1, <100 mm(2); group 2, 101-200 mm(2); group 3, 201-400 mm(2)). RESULTS: The mean stone size was 142.08+/-86.3 mm(2). Overall stone-free rate was 53.6%. Localization of clinically significant or insignificant residual fragments was in the lower calix, renal pelvis, and both in 50 (32.6%), 29 (18.9%), and 8 (5.2%) patients, respectively. There was no statistically significant difference in pelvicaliceal anatomic features except narrower IPA (P=0.02) in group 1 patients with residual stones. CONCLUSION: The falling of stone fragments to the lower calix in spite of the ureter whether clinically significant or not after SWL of pelvic stones initially seems to be related to stone burden rather than lower caliceal anatomy. However, existence of a more narrow IPA in group 1 patients with residual fragments led us to believe that lower-pole IPA can play a role in stone clearance, especially for smaller stones, probably because of smaller residual fragment size or the more mobile nature of the primary stone.

RESUMEN

Here we report a patient with symptomatic mobile kidney (nephroptosis) who was treated successfully with transperitoneal laparoscopic nephropexy with the use of nonabsorbable polymer clips. In this procedure, clips were used on Gerota's fascia to fix the kidney to the transversus abdominis fascia and the triangular ligament. This method is easier and requires less time than previously reported techniques.

RESUMEN

AIM: Our aim was to evaluate the impact of pelvicaliceal variables in pediatric and adult age groups who underwent SWL for lower caliceal calculi. METHODS: 25 pediatric and 78 adult patients treated with extracorporeal shock wave lithotripsy (SWL) between 1996 and 2004 were enrolled into the study after exclusion of patients with hydronephrosis, major renal anatomic anomalies, non-calcium stones, history of recurrent stone disease and previous renal surgery. Lower pole infundibulopelvic angle (IPA), infundibular length (IL), infundibular width (IW) and pelvicaliceal volume were measured from pre-SWL intravenous urography. The pelvicaliceal stone load (PSL) index implicating the stone burden of each patient described as the relationship between stone volume and total estimated pelvicaliceal volume for stone-bearing kidney was also calculated. RESULTS: Sixty-eight percent of adult and 80% of pediatric patients became stone-free after SWL. The statistical insignificance between PSL index (p=0.097) of two groups shows that both groups shared a similar stone burden. According to SWL outcome, mean IPA values of stone-free and residual patients were 46.85 degrees and 30 degrees in pediatric group, respectively (p=0.01), whereas these values were 48.08 degrees and 43.06 degrees in the adult group, respectively (p=0.352). In the pediatric age group, stone-free and cumulative success rates increased with increasing IPA but this correlation was statistically insignificant (p: 0.263). CONCLUSIONS: Lower caliceal anatomy has a higher impact on stone clearance after SWL in pediatric patients and urologists can expect better SWL outcomes from pediatric population with solitary lower caliceal stone than adults under the same conditions.

RESUMEN

Here, we present a patient who underwent transperitoneal laparoscopic nephrectomy for a nonfunctional kidney on the left side, and who was found to have xanthogranulomatous pyelonephritis (XGP) on the subsequent histopathology examination. XGP is a severe, chronic infection of the renal parenchyma. Nephrectomy is the treatment of choice. Preoperative diagnosis of XGP can be challenging because the clinical presentation may vary. Our patient's loss of kidney function was due to a simple cortical kidney cyst that compressed the urinary collecting system. He presented only with mild flank pain and a poorly functioning kidney, and therefore XGP was not suspected before surgery. Because of the renal and perirenal inflammatory changes that commonly accompany XGP, the laparoscopic approach is difficult and is therefore rarely used. However, laparoscopic nephrectomy for XGP offers an easier recovery for the patient and therefore deserves further consideration as a method of treatment.

RESUMEN

The goal of this study was to determine the factors affecting stone clearance after extracorporeal shock wave lithotripsy (ESWL) for lower caliceal stones. Lower pole stone clearance was investigated in 128 (80 males, 48 females) patients treated with ESWL during 1998-2003 in our clinic. Renal anatomy was determined on standard intravenous urogram. The lower infundibulopelvic angle (LIPA) was measured as the angle between the vertical pelvis axis and the vertical axis of lower infundibulum (Sampaio's method). The mean age of the patients was 42.8 +/- 12.4 (19-77) years. The mean stone diameter and burden were found to be 1.28 +/- 0.58 (0.5-3.5) cm and 1.2 +/- 1 (0-7) cm(2) respectively. The stone-free rate was 62.5% and ESWL was unsuccessful in 16 (12.5%) patients. Thirty-two (25%) patients had residual fragments < or =4 mm retained in lower calices after lithotripsy. The stone clearance was found to be unrelated to stone burden and diameter (P = 0.17 and P = 0.14, respectively). However, there was a significant difference between mean lower pole infundibulum length (P = 0.001), infundibulum width (P = 0.001) and LIPA (P = 0.0001) between stone-free patients and patients with residual fragments. Multivariate logistic regression analysis accepting stone-free as the favourable result also confirmed that LIPA, lower pole infundibulum length and width were factors that significantly affected the outcome.

RESUMEN

OBJECTIVE: This study was organized to form a symptom scale for diagnosis and assessment of urinary and bowel symptoms in children with dysfunctional elimination syndrome (DES). METHODS: The study group included 81 children presented to our clinic with symptoms of DES like enuresis, abnormal voiding, urinary tract infection and urgency, between January 2003 and February 2004. Age matched 102 children with no history of urological complaints were randomly recruited from a public school as control group. Children with isolated, mono-symptomatic nocturnal enuresis were not taken to the study. All children and parents were requested to fill a 35-item questionnaire related to symptoms of DES. After statistical analysis, questions from the initial form that had a P-value <0.05 and an area under curve (AUC) value >0.6 were selected to form a final scale. RESULTS: The mean ages for study and control groups were 8.7 +/- 2.5 and 8.3 +/- 2.2 years, respectively (P = 0.236). The final scale was composed of 15 questions. The cut-off score for the presence of DES was determined as 7.5 (sensitivity 85.2%, specificity 93.1%, AUC value = 0.943) for the total population. When only the male population were concerned the cut-off score was 4.5 (sensitivity 93.8%, specificity 78%, AUC value = 0.913) while the cut-off score for the female population was 7.5 (sensitivity 87.7%, specificity 94.2%, AUC value = 0.953). CONCLUSION: Providing objective assessment of symptom severity, formation of a validated scoring system for children with DES might be a good tool for diagnosis, confirmation of treatment results and follow up. It might also be useful for screening purposes.

RESUMEN

INTRODUCTION: Of late, little data is available concerning factors affecting female sexual function. In the present study, we evaluated the effects of overactive bladder (OAB) syndrome symptoms on female sexual function. MATERIALS AND METHODS: 40 patients with OAB symptoms and 40 age-matched women as a control group were evaluated using the Female Sexual Function Index (FSFI) for sexual function. According to the presence of urge incontinence, women with OAB were also divided into wet and dry groups. After completion of the forms, groups were compared. RESULTS: Although scores of all domains of FSFI (desire, arousal, lubrication, orgasm, satisfaction, pain and total) in the OAB group were found to be lower than in the control group, only 'desire' was found to be significantly different (p = 0.035). The FSFI scores of the OAB-dry and OAB-wet group were similar to each other. CONCLUSION: The results indicate that there is a trend toward lower sexual function scores in women with OAB compared to controls.

RESUMEN

OBJECTIVE: To evaluate the effectiveness of pneumatic lithotripsy (PL) with ureteroscopy in the treatment of large ureteral stones. METHODS: We reviewed, retrospectively, the records of 156 patients (122 male, 34 female) who had ureteral calculi larger than 10 mm that were treated with PL. Of these patients, 41 (26.3%) were treated primarily with PL and 115 (73.7%) were treated secondarily after unsuccessful extracorporeal shock wave lithotripsy (SWL). The mean stone diameter was 12.87 mm (range 10-20.5 mm). Results were evaluated 3 months after treatment by excretory urography and/or ultrasonography. RESULTS: The overall stone-free and fragmentation rates (FRs) were 85.2 and 92.3%, respectively. Corresponding values were 60 and 84% for upper ureteral stones, 79.5 and 89.7% for middle ureter stones and 94.5 and 95.6% for lower ureteral stones, respectively. The main complications were migration of a complete stone or of fragments (7.1%), urosepsis (4.5%) and ureteral perforation (1.3%). CONCLUSIONS: Although SWL is generally accepted as the first treatment option for ureteral stones because of its non-invasive nature, PL with ureteroscopy seems to be a good alternative with the advantage of higher success rates and quick stone clearance. Especially when we take the importance of quick stone removal into account for larger ureteral stones, which are more likely to have obstruction, impaction, or infection, we believe that PL may be chosen as the first line treatment rather than SWL for stones larger than 10 mm.
