Female sexual dysfunction in urinary and double incontinence.

OBJECTIVES: To evaluate the sexual function of women with urinary incontinence (UI) and double incontinence (DI) comparing with a healthy control group by using the Female Sexual Function Index (FSFI). METHODS: This study was designed as a retrospective study consisting of UI, DI, and a control group, each containing age-matched 40 patients. Statistical comparisons were made among the UI, DI, and control groups in terms of the FSFI total score as well as each domain's score. RESULTS: The FSFI total scores were found to be 22.92, 20.53, and 20.32 for the control, UI, and DI groups, respectively, and no statistically significant difference was found among the groups. A statistically significant difference existed among the groups only in terms of satisfaction and pain. Significantly higher pain was found in the UI and DI groups compared with the control group (p=0.007 and p<0.001). Although there was significantly lower satisfaction in the DI group compared with the control group (p=0.012), no significant difference was found between the UI and control groups. CONCLUSION: The pain in the UI group and the pain and the low satisfaction in the DI group might be parameters that cause sexual dysfunction.

Urologic Complications After Renal Transplant: A Single-Center Experience.

OBJECTIVES: Urologic complications after kidney transplant are associated with significant morbidity, mortality, and prolonged hospital stay. An intervention or second surgical procedure is frequently required. Here, we report urologic complications in adult kidney recipients. MATERIALS AND METHODS: Since 2006, 171 adult kidney transplant procedures have been performed at the Gazi University Transplantation Center (Ankara, Turkey). Among these patients, there were 65 adult female (38%) and 106 adult male (62%) recipients. Donor source included 61 deceased donations (36%) and 110 living related donations (64%). The Haberal corner-saving technique was used for ureteroneocystostomy anastomosis. All recipients received a calcineurin-based triple immunosuppression regimen. All recipients also received trimethoprim/sulfamethoxazole prophylaxis for 3 months after transplant. RESULTS: In the 171 adult kidney recipients analyzed for urologic complications, mean age was 32.5 ± 14.1 years (median: 32.5 y; range, 18-67 y); mean donor age was 41 ± 14.2 years (median: 42 y). We focused on 3 specific urologic complications: urine leak, ureteric stenosis, and symptomatic vesicoureteral reflux. In our study group, urologic complications were encountered in 7 patients (4%), with 5 complications detected in the early period and 2 complications detected in the late period. No symptomatic vesicoureteral reflux complications were shown in this study group. Urologic complications did not result in any patient deaths or graft loss. CONCLUSIONS: In this study, the Haberal corner-saving suture technique with double J stent seemed to have a protective effect for development of urologic complications.

Successful treatment of sodium oxalate induced urolithiasis with Helichrysum flowers.

ETHNOPHARMACOLOGICAL RELEVANCE: Helichrysum (Asteraceae) flowers, known as "altin otu, yayla çiçegi, kudama çiçegi" , are widely used to remove kidney stones and for their diuretic properties in Turkey. AIM OF THE STUDY: To determine the curative effect of infusions prepared from capitulums of Helichrysum graveolens (M. Bieb.) Sweet (HG) and H. stoechas ssp. barellieri (Ten.) Nyman (HS) on sodium oxalate induced kidney stones. MATERIALS AND METHODS: Infusions prepared from the capitulums of HG and HS were tested for their curative effect on calcium oxalate deposition induced by sodium oxalate (70mg/kg i.p.). Following the injection of sodium oxalate for 5 days, plant extracts were administered to rats at two different doses. Potassium citrate was used as positive control. Water intake, urine volume, body, liver and kidney weights were measured; biochemical and hematological analyses were conducted on urine and blood samples. Additionally, histopathological examinations were done on kidney samples. RESULTS: H. stoechas extract showed prominent effect at 156mg/kg dose (stone formation score: 0.33), whereas number of kidney stones was maximum in sodium oxalate group (stone formation score: 2.33). The reduction in the uric acid and oxalate levels of urine samples and the elevation in the urine citrate levels are significant and promising in extract groups. Some hematological, biochemical and enzymatic markers are also ameliorated by the extracts. CONCLUSIONS: This is the first report on the curative effect of immortal flowers. Our preliminary study indicated that Helichrysum extracts may be used for treatment of urolithiasis and Helichrysum extracts are an alternative therapy to potassium citrate for patients suffering from kidney stones.

Changes in Cajal cell density in ureteropelvic junction obstruction in children.

INTRODUCTION: Congenital ureteropelvic junction obstruction is one the most common causes of neonatal hydronephrosis. The etiology of the ureteropelvic junction (UPJ) obstruction has not been clearly established. The presence of a hypoplastic, adynamic ureteral segment is thought to be the major cause of an UPJ obstruction. OBJECTIVE: We evaluated the distribution of Cajal cells using immunohistologic methods coupled with light microscopy of the UPJ tissues in obstructed and normal UPJs. STUDY DESIGN: The study group consisted of 19 patients who underwent pyeloplasty for UPJ obstruction. Twelve patients who had been operated on for oncological indications constituted the control group. The sections were stained immunohistochemically using CD117 (c-kit) antibody; the numbers of CD117 (+) interstitial cells of Cajal were counted in 10 consecutive high-power fields under the light microscope and the cell density was determined for each case. RESULTS: The mean age of the cases who underwent dismembered pyeloplasty and the control group were 116 ± 116 months (14 male, 5 female; 6-420 months) and 279 ± 312 months (9 male, 3 female; 24-948 months) (p = 0.1), respectively. The mean interstitial Cajal cell number in the UPJ obstruction and the control groups were 2.37 ± 2.19 and 24.5 ± 9.73, respectively (p < 0.0001). Thirteen (68.4%) patients had very few, five (26.3%) patients had few, and one (5.3%) patient had many Cajal cells in the UPJ obstruction group. In the control group, all patients had more than seven cells per high-power field. DISCUSSION: We found that in cases of UPJ, obstruction the numbers of interstitial Cajal cells were decreased, being either absent or significantly reduced. Although data about the motility are currently not sufficient, the decrease in the number of Cajal cells in patients with UPJ highlights that they might be responsible for the initiation, coordination, and conduction of peristaltic activity along the pelvicalyceal system. Improvement and enhancement of contraction waves arising from the upper urinary system depend on interstitial cells of Cajal, which are the pacemaker cells in smooth muscles. We think that a decreased number of interstitial cells of Cajal have a close relationship with changing ureteral motility when we compare our UPJ obstruction cases with the limited data in the literature. CONCLUSION: Further investigations on these cells will probably give detailed information about the neurophysiology of the urinary system and the diseases that cause congenital hydronephrosis.

Preventive treatment of calcium oxalate crystal deposition with immortal flowers.

ETHNOPHARMACOLOGICAL RELEVANCE: A number of medicinal plants are used for their diuretic, urolithiatic and anti-inflammatory effects on urinary system problems in Turkey and the most common traditional remedy for kidney stones is the tea of immortal flowers. The aim of this study is to evaluate the preventive effect of infusions prepared from capitulums of Helichrysum graveolens (M.Bieb.) Sweet (HG) and Helichrysum stoechas ssp. barellieri (Ten.) Nyman (HS) on formation of kidney stones. MATERIALS AND METHOD: Sodium oxalate (Ox-70mg/kg intraperitoneally) was used to induce kidney stones on Wistar albino rats. At the same time, two different doses of the plant extracts (HG: 62.5 and 125mg/kg; HS: 78 and 156mg/kg) were dissolved in the drinking water and administered to animals for 5 days. Potassium citrate was used as positive control in the experiments. During the experiment, water intake, urine volume and body weights of the animals were recorded. At the end of the experiments, liver, kidney and body weights of the animals were determined; biochemical analysis were conducted on urine, blood and plasma samples. Histopathological changes in kidney tissues were examined and statistical analysis were evaluated. RESULTS: HS extract showed the highest preventive effect at 156mg/kg dose (stone formation score: 1.16), whereas a number of kidney stones were maximum in sodium oxalate group (stone formation score: 2.66). Helichrysum extracts decreased urine oxalate and uric acid levels and increased citrate levels significantly. In addition, Helichrysum extracts regulated the negative changes in biochemical and hematological parameters occurred after Ox injection. CONCLUSIONS: We conclude that Helichrysum extracts could reduce the formation and growth of kidney stones in Ox-induced urolithiasis and can be beneficial for patients with recurrent stones. In addition, this is the first study on the preventive effect of immortal flowers.

Direct upper kidney pole access and early ligation of renal pedicle significantly facilitates transperitoneal laparoscopic nephrectomy procedures: Tunc technique.

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.

E-cadherin gene 3'-UTR C/T polymorphism in Turkish patients with nephrolithiasis.

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.

A HindIII polymorphism of fibronectin gene is associated with nephrolithiasis.

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.

Heparan sulfate gene polymorphism in calcium oxalate nephrolithiasis.

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.

Laparoscopic nephrectomy for xanthogranulomatous pyelonephritis in the absence of kidney stones or clinical urinary infection.

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.

The impact of radiological anatomy in clearance of lower caliceal stones after shock wave lithotripsy.

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. Lower pole anatomy has a significant influence on clearance of fragments after ESWL.

Evaluation of sexual function in women with overactive bladder syndrome.

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.

Parameatal cyst of urethra: a rare congenital anomaly.

We report a case of parameatal urethral cyst in a 15-year-old boy which is a very rare congenital anomaly. The cyst recognized at infancy but the boy presented to our clinic at the age of 15 when the mass was grown enough to cause spraying of urine and poor cosmesis. Complete excision of the cyst with total removal of the epithelium is the required for treatment and prevention of recurrence.

Prolapse of a simple ureterocele presenting as a vulval mass in a woman.

A 48-year-old woman presented with a large vulval mass after prolapse of a ureterocele. Her past excretory urogram showed a filling defect (cobra head appearance) in the bladder related to a single-system ureterocele on the left. The mass was manually reduced back through to the urethra under sedation and a urethral catheter was inserted. The anterior wall of the ureterocele was resected transurethrally for definitive treatment.

Factors affecting the success rate of extracorporeal shock wave lithotripsy for renal calculi in children.

The aim of the study was to analyse factors affecting the success rate of extracorporeal shock wave lithotripsy (ESWL) in children with renal calculi. We performed a retrospective analysis reviewing records of 85 (40 female, 45 male) children (89 renal units) subjected to ESWL for treatment of renal calculi during 1990-2005 in our department. As 4 patients had bilateral calculi and 19 children (21 renal units) had renal stones at more than one different site, each location was analysed separately for convenience. The mean age of the patients was 10.3+/-4.6 (2-16) years. The stone-free rates for renal pelvis, lower, middle and upper caliceal calculi were 70, 62, 50 and 73%, respectively. A higher rate (33%) of insignificant fragments (< or = 4 mm) was noted for lower pole calculi. Increased stone diameter (P=0.0001) and burden (P=0.04) were found as the most significant factors that adversely affect the stone-free rate for pelvis renalis calculi, whereas an acutely oriented infundibulum and/or a long lower infundibulum (P=0.005) were unfavourable factors for clearance of lower caliceal stones. The stone-free rate in children with multiple calculi was 48%, while 29% of the renal units had retained fragments. ESWL is a good initial option for treatment of most of the renal calculi < 2 cm except in the presence of unfavourable lower caliceal anatomy. Increased stone burden, multiple stones, staghorn calculi, narrow lower infundibulopelvic angle and long lower infundibulum are factors that adversely affect the clearance rate.

The impact of urinary incontinence on female sexual function.

Although urinary incontinence is not a life-threatening disorder, it has been shown to have detrimental effects on quality of life in terms of psychological, social, and sexual problems. In this study, investigators explored the effects of different types of urinary incontinence on female sexual function with a reliable and validated questionnaire, the Female Sexual Function Index (FSFI). One hundred fifty-three women with complaints of incontinence were enrolled in the study. An age-matched group of 89 women who had no incontinence or lower urinary tract disorders were enrolled as a control group; all completed the FSFI. Incontinence was classified as urge, stress, and mixed type. Pelvic organ prolapse (POP), if present, was also recorded. FSFI scores were compared between the incontinent and control groups. A multivariate linear regression analysis model was used to explore the effects of patient characteristics on total FSFI domain score. All domain scores of FSFI except lubrication and pain were statistically significant in the incontinence group (for total domain score, P=.005). For FSFI, in terms of types of incontinence, the difference was significant when the group with mixed urinary incontinence was compared with the control group. In multivariate linear regression analysis, age, presence of POP, and mode of delivery were predictors of female sexual function. Mixed urinary incontinence, when compared with other types, had a significant impact on sexual function. When POP was also present, no negative effects were noted in incontinent women.

Extracorporeal shock wave lithotripsy in L-shaped kidneys: report of two cases.

The L-shaped or tandem kidney is a type of crossed ectopia with fusion in which the crossed kidney assumes a transverse position during its attachment to the inferior pole of the other kidney. Calculus formation is a well-known sequel of congenital abnormalities of the urinary tract and we like to present two patients harbouring calculi in L-shaped kidneys treated by extracorporeal shock wave lithotripsy (ESWL). The first patient had a calculus in renal pelvis of the transverse kidney. The second case had multiple calculi in renal pelvis and calices of the vertically positioned kidney. After three sessions, first patient was stone free, whereas no fragmentation in the second case. As a conclusion, ESWL might be an option for L-shaped kidneys.

Renal brucelloma: a rare infection of the kidney.

We report a case of renal abscess caused by brucellosis (renal brucelloma) which was treated by surgery. Renal parenchymal involvement of systemic brucellosis is a very rare condition and relapses after medical treatment, such as solid organ abscess including kidney, should be especially considered. In chronic cases, laboratory findings including polymerase chain-reaction examination is needed for definitive diagnosis.
