RESUMO

BACKGROUND: The aim of this study was to compare metabolic parameters, plasma Osteopontin (OPN) and Hepatocyte Growth Factor (HGF) levels between Sleeve Gastrectomy (SG) patients in their 6th post-operation month and healthy control patients. METHODS: Height, weight, Body Mass Index (BMI) and laboratory parameters of 58 SG patients aged 18‒65 years (Group 1) and 46 healthy control patients (Group 2) were compared. In addition, preoperative and postoperative sixth-month BMI and laboratory parameters of the patients in Group 1 were compared. RESULTS: The mean age and gender distributions of the groups were similar (p > 0.05). Mean BMI was 28.9 kg/m2 in Group 1 and 27 kg/m2 in Group 2 (p < 0.01). While plasma HGF levels were similar between both groups, plasma OPN levels were higher in Group 2 (p < 0.001). Fasting plasma glucose, total cholesterol, triglyceride, fasting plasma insulin and insulin resistance values were higher in Group 1, while alanine aminotransferase and aspartate aminotransferase levels were higher in Group 2 (p < 0.05). There was a strong correlation between plasma HGF and OPN levels in Group 1, but not in Group 2 (Rho = 0.805, p < 0.001). CONCLUSION: OPN and HGF are promising biomarkers that can be used to better understand and detect problems related to obesity. The fact that patients in the early post-SG period had lower plasma OPN and similar plasma HGF compared to non-surgical patients of similar age and gender with higher BMI may be another favorable and previously unknown metabolic effect of SG.

RESUMO

BACKGROUND/OBJECTIVE: Cholelithiasis is a common disease but pose significant global health and financial burdens. Mechanisms of the disease are associated with insulin resistance (IR), obesity, metabolic syndrome, and type 2 diabetes. Insulin resistance is commonly observed in cholelithiasis patients. More recently, the triglyceride-glucose (TyG) index has been proposed as an alternative marker of insulin resistance. In our study we aimed to understand whether the TyG index is correlated with HOMA-IR in cholelithiasis patients. And also we aimed the predict a cutoff value for determining insulin resistance in cholelithiasis patients. METHODS: A total of 184 cholelithiasis patients were matched in terms of age, gender, and BMI. They were divided into two groups based on their Homa IR levels (IR and Non-IR group). This study was a retrospective, observational study and clinical data was obtained from electronic medical records. Cutoff value for Tyg index was established through ROC Analysis. Binary Logistic Regression was used to identify factors affecting insulin resistance. RESULTS: A significant cutoff value was found for the TyG index in determining the presence of insulin resistance. Having a TyG index of ≥8.71 indicates the presence of insulin resistance. The sensitivity was 68.48%, the specificity was 58.70%. Binary Logistic Regression analyses showed that an increase in Tyg Index, waist circumference and waist-to-height ratio values increases the risk of insulin resistance by 2.705 (p = 0.001), 1.032 (p = 0.029), and 334.057 (p = 0.012) times respectively. CONCLUSION: Our study indicated that TyG index is positively correlated with HOMA-IR. TyG index was found as a risk factor for insulin resistance.

RESUMO

BACKGROUND: The aim of the study was to investigate the predictive value of hyponatremia as a new biochemical marker for the early and accurate preoperative diagnosis of complicated appendicitis in the adult population. METHODS: 732 patients who were operated for acute appendicitis (AA) and diagnosed as perforation intraoperatively were evaluated retrospectively. Serum sodium, C-reactive protein (CRP), and leukocyte levels of patients with perforated and nonperforated appendicitis were compared. RESULTS: Perforated appendicitis patients had statistically lower serum Na values (p<0.001). Similarly, patients without perforated appendicitis had higher serum CRP values (p<0.001). In patients diagnosed with perforated AA, the sensitivity of plasma sodium concentration was 63%, and the specificity was 66%. The threshold value of plasma sodium concentration ≤137.5 mEq/L had the best possible sensitivity and specificity. CONCLUSION: Hyponatremia is a new marker of perforated appendicitis and therefore, serum sodium level measurement should be considered in patients with a clinical presentation consistent with appendicitis if complications are suspected.

RESUMO

Introduction Biomarkers such as the neutrophil-lymphocyte ratio (NLR) and the platelet-lymphocyte ratio (PLR) are associated with the colon tumor stage and prognosis. Therefore, in our study, we investigated whether these biomarkers are important in determining the colon cancer stage. Materials and methods The outcomes in 268 patients operated on with the diagnosis of colon cancer between January 2011 and March 2019 were retrospectively analyzed. The relationship of the stage of the patients with the NLR or PLR was evaluated. In addition, according to the stage of colorectal tumors, stage I and other stages (stages II, III, and IV) were compared in terms of NLR and PLR. Groups that had lymph node (LN) metastasis were compared with those that did not. Finally, groups with and without metastasis were also compared. Results In our cohort, 144 patients (57.6%) were male, and 84 (42.4%) were female. The mean age was found to be 68.28 ±12.71 years. The patients were evaluated according to their stages: 26 patients were stage I, 78 patients were stage II, 75 patients were stage III, and 19 patients were stage IV. There was a significant difference in NLR values between the groups (p: 0.05). Also, 104 patients were LN-negative (stages I-II), and 94 patients were LN-positive (stages III-IV). When PLR was compared between the two groups, no significant difference was found between tumor stages and these values (p: 0.099). However, there was a significant difference in NLR values (p: 0.034). Conclusion  Based on our findings, it has been concluded that increased PLR may not be associated with the colon cancer stage. However, the increase in NLR was found to be correlated with tumor stage and LN metastasis.

RESUMO

BACKGROUND: An incarcerated hernia is a part of the intestine or abdominal tissue that becomes trapped in the sac of a hernia. An increase in morbidity and mortality occurs after intestinal resections from strangulated hernias. This study aims to examine the markers that may be effective in determining the risk of small bowel resection due to incarcerated hernias. In particular, we aimed to investigate the effect s of blood lactate levels in determining this risk. METHODS: A cross-sectional retrospective study was designed. Patients, whose preoperative diagnosis were reported as incarcerated hernia and had essential information, were included in this study. They were divided into two groups according to whether they had resection or not. Age, gender, hernia type, hernia side, resection material, blood lactate level (BLL), white blood cell (WBC), neutrophil count (NE), lymphocyte count (LY), neutrophil/lymphocyte ratio (NLR), platelet count (PLT), lactate dehydrogenase (LDH), radiologic bowel obstruction sign and comorbidities were evaluated. RESULTS: Sixty-seven patients were included in this study. It was observed that 16 (23.9%) of these patients underwent small intestinal resection, 16 (23.9%) had an omentum resection, while no resection was performed on 35 (52.2%) patients. There was a statistically significant difference regarding radiologically intestinal obstruction (p=0.001), hernia type (p=0.005), BLL (p<0.001), WBC, NLR and LDH values (p<0.05). In incarcerated hernia patients with a lactate value ≥1.46 mg/dL, sensitivity was observed to be 84.0% and specificity 86.0% (p<0.001). CONCLUSION: In patients with a preliminary diagnosis of an incarcerated hernia, the risk of possible small bowel resection is the most important point in deciding for an operation. The presence of an intestinal obstruction in radiological examinations, and particularly the high levels of WBC, NLR, LDH and BLL, may indicate a necessity for possible small bowel resection. Concerning the risk associated with small bowel resection, blood lactate levels ≥1.46 mg/dL may be alerting.

RESUMO

BACKGROUND: Although many options exist for surgical treatment of pilonidal sinus disease (PSD), consensus has not yet been achieved, as all surgical methods have various rates of complications, postoperative infection, and recurrence. METHODS: This study was a prospective, randomized, clinical trial, and was conducted with consecutive 100 patients admitted to Ankara Military Hospital General Surgery Service for treatment of PSD from May 2013 to August 2013. This study compared two surgical treatments for PSD: modified Limberg flap transposition and lateral advancement flap transposition with Burow's triangle. The patients received surgical treatment with either modified Limberg flap transposition (n = 50) or lateral advancement flap transposition with Burow's triangle (n = 50). Clinical healing period, length of hospital stay, operative time, postoperative complications including recurrence, wound dehiscence, and surgical site infection, as noted during postoperative follow-up period; Visual Analog Scale scores for pain. RESULTS: The mean follow-up period was 12 months. No significant differences were observed between the 2 groups in length of hospital stay (P = .515), operative time (P = .175), wound dehiscence (P = .645), and Visual Analog Scale pain scores (P = .112). The mean operative times were 42.5 minutes in the modified Limberg group and 40.0 minutes in the lateral advancement group. CONCLUSIONS: Although lateral advancement flap transposition with Burow's triangle is used less often than modified Limberg flap transposition, we could not determine a parameter that was statistically different such as operative time, postoperative complication, or the length of hospital stay. Hence, the lateral advancement flap is as viable an option as other more preferable techniques in the treatment of PSD, which particularly settled on the upper segment without a deep natal cleft.

RESUMO

PURPOSE: The present study evaluates the efficiency and reliability of a hemostatic agent ABS (Ankaferd Blood Stopper(®)) in tubeless percutaneous nephrolithotomy (PCNL). PATIENTS AND METHODS: A total of 90 patients were divided into two subgroups. The first group had ABS applied during the intervention, whereas the control group underwent regular tubeless PCNL in this prospective randomized study. Age, stone size, operative time, postoperative hemoglobin change, renal parenchyma thickness, postoperative ureteral catheter removal time, access number, nephroscope time, blood transfusion rate, serum creatinine change, complication rate, visual analogue scale (VAS), and hospitalization time were compared between the two groups. RESULTS: Preoperative and postoperative data obtained from both groups were compared. No statistically meaningful differences were found related to variables of mean age, stone size, access number, serum creatinine change, operative time, renal parenchyma thickness, VAS scores, and hospitalization period. Whereas the nephroscope time (minutes) was longer in the ABS group (Group 1 [G1]:3, 33±1, 72 vs G2:2, 62±1, 43, P=0.035), hemoglobin (Hb) decrease, and urine clarity time were statistically lower compared with the control group. Hb decrease was (mg/dL) (G1: 1.40±1.04 vs G2: 1.84±1.15, P=0.034), and urine clarity time was (hour) (G1: 9.60±5.50 vs G2: 11.95±4.71, P=0.012), respectively. Complications were encountered in three (6.6%) patients of the ABS group and in four (8.8%) of the control group. CONCLUSION: ABS is an efficient and reliable hemostatic agent in tubeless PCNL. Comparative studies are needed, however, with other hemostatic agents that might be applied in tubeless PCNL.

RESUMO

We aimed to investigate the safety and efficacy of tubeless percutaneous nephrolithotomy (PCNL) with ureteral catheter or double-J stent in comparison with standard PCNL in our study. We retrospectively evaluated 707 of 1,469 patients with stone area under 800 mm(2) and only one subcostal nephrostomy access that was underwent PCNL between March 2004 and October 2011 in our clinic. Patients with 14F nephrostomy tube (Malecot or Re-entry catheter), with ureteral stent and with antegrade double-J stent were included into Group 1 (n = 180), Group 2 (n = 148) and Group 3 (n = 120), respectively. The mean hospitalization time of patients in Group 1 was significantly longer. The mean VAS was significantly higher in Group 1. On the other hand the mean fluoroscopy and operation time of patients in Group 2 were significantly shorter in comparison with other groups. Number of patients with postoperative transfusion requirement was significantly higher in Group 1. The number of patients with postoperative narcotic analgesic requirement was also significantly higher in Group 1. The most frequent complication in our study was prolonged drainage. The postoperative complications were seen more frequently in Group 1. Both ureter catheter and double j stent were more comfortable, effective and safe in urinary drainage following PCNL with single sub-costal access. On the other hand, double-J stent has a disadvantage as requirement additional cystoscopy for removal. We suggest ureter catheter or double-J stent to preserve short- and long-term urinary drainage.

RESUMO

OBJECTIVE: To detect the possible alterations on density or sensitivity of α1-adrenergic subtypes in diabetic bladder by reverse transcriptase-polymerase chain reaction technology and in vitro studies. METHODS: Experimental diabetes was induced by administration of streptozotocin with a single injection through the tail vein. Rats were divided into control and diabetic groups. Contractile responses of bladder strips from each group were obtained for postassium chloride, adenosine triphosphate, and electrical field stimulation (0.5-32 Hz) in organ bath. Electrical field stimulation responses of strips were evaluated in the presence of PPADS (nonselective P2 antagonist), atropine (cholinergic antagonist), 5 MU (α-1a-adrenergic antagonist), BMY-7378 (α-1d-adrenergic antagonist), and finally CED (α-1b-adrenergic antagonist). mRNA expression of α1-adrenergic subtypes was determined for each group. RESULTS: The difference between contractile responses related to electrical field stimulation with incubation with PPADS, atropine, 5 MU, BMY-7378, and CED, respectively, was not significant in the control and diabetic groups (P > .05). The electrical field stimulation responses of strips at 0.5-2 Hz without incubation were significantly different between the control and diabetic groups (P < .05). The contractile responses of strips with PPADS + atropine + 5 MU and BMY-7378 incubations in the diabetic group were significantly lower than in the control group in all doses (P < .05), The mRNA expression of α-1a-adrenergic in the diabetic group was significantly lower than in the control group (P < .05). No change was found in the expression of mRNA of α-1b-adrenergic. CONCLUSION: These results support the probability of changes in presynaptic and autonomic receptor sensitivity. We believe that α-1a-adrenergic and α-1d-adrenergic subtypes should be kept in mind in the treatment of diabetic cystopathy.

RESUMO

The treatment of large proximal ureteral stones continues to be controversial. We evaluated the antegrade percutaneous approaches for the proximal ureteral stones in our clinic. In this study, 73 percutaneous antegrade ureteroscopy (PAU) operations applied to proximal ureteral stones between February 2005 and December 2009 were included. The stones were located between ureteropelvic junction and 4th lumbar vertebra. PAUs were applied through appropriate calyx with the patients in prone position. During operations, amplatz dilatators were used for dilatation, and pneumatic lithotripter was used for stone fragmentation. Patients were evaluated according to their success rate, complications, hospitalization period, and preference of drainage tube etc. Patients' mean age was 52.21 years, the mean stone diameter was 19.47 mm (range 15-25), the mean stone burden was 283.76 ± 49.12 mm(2) (mean ± SD) (range 188.5-392.7) and the mean hospitalization time 1.69 days. Single access done in 68 patients and two accesses were needed in 5 patients. Sixty-eight patients (93.1%) became stone-free. Nephrostomy tubes were placed in 12 patients after operation, while tubeless approach was preferred in 61 patients. Complications were seen in five patients. There were not any complications reported during the follow-up period. PAU is an effective and safe treatment modality if appropriate calyx access was performed. The possibility of renal stone treatment in the same session is an important advantage of this modality.

RESUMO

OBJECTIVE: We aimed to evaluate the efficacy and safety of percutaneous nephrolithotomy (PNL) in infants and small children (12-36 months). METHODS: The PNL applications conducted in children <3 years of age in two centers were evaluated. Whereas pediatric PNL instrumentation was used in the first center, adult-size instrumentation was utilized in the second center. The complications were given according to the modified Clavien classification system. RESULTS: The mean age of the patients was 22.76 months (5-36 months) and the mean body weight was 11.51 kg (6-15 kg). In twelve renal units, pediatric instrumentation was used and among these, two had miniperc. In the other eight renal units, adult-size instrumentation was employed. Except for the patient with complex renal stones, all patients were stone free after the intervention and none required a conversion to open surgery. There were grade 1-2 complications in 3 patients. The postoperative hemoglobin drop was greater in the children who underwent PNL with adult-size instrumentation. CONCLUSION: In this young age group, in addition to standard PNL, simultaneous bilateral PNL, tubeless PNL and in urgent cases of renal failure, urgent PNL, are safe and effective treatment modalities provided patients are selected properly and the surgeon performing the procedure has the necessary experience.

RESUMO

The peripheral cutting balloon has been used to treat various nonvascular strictures as well as vascular stenosis. In this article, we describe for the first time the use of the cutting balloon in the treatment of patients with urethral stricture. Four patients with bulbar urethral stricture were included in the study. All strictures were successfully dilated with the cutting balloon, and patients were free of symptoms at 6-month follow-up. Cutting-balloon dilatation is a safe, easy-to-perform, and effective treatment for patients with tight urethral strictures.

RESUMO

PURPOSE: We prospectively analyzed the outcome of tubeless percutaneous nephrolithotomies (PCNLs) using two different stenting techniques (i.e., externalized ureteral catheter compared with Double-J placement) without strict exclusion or inclusion criteria. PATIENTS AND METHODS: Forty-six patients who were undergoing tubeless PCNL were randomized to two groups: Group 1 (tubeless PCNL with externalized ureteral catheter) and group 2 (tubeless PCNL with Double-J placement). The only exclusion criterion was presence of significant residual stones. The two groups were comparable with regard to age, sex, stone laterality, stone burden, and number of previous open renal surgeries. Factors evaluated included operative time, stent-related symptoms, analgesic requirement, postoperative pain, postoperative morbidity, hospital stay, blood loss, and success rates. RESULTS: The mean operative times, mean number of accesses, percentage of supracostal accesses, mean visual analog scale scores, analgesic requirements, mean decreases in hemoglobin level, blood transfusion rates, success rates, and mean hospital stays were not statistically significant in both groups. The only statistically significant difference between groups was the postoperative stent-related symptoms. In group 2, 52.1% experienced some sort of stent-related symptoms. In most of the patients, these symptoms were not severe; however, in two of them (16.6 %), oral medication therapy with anticholinergics was needed. None of the patients in group 1 had stent-related symptoms and needed medication (P < 0.01). CONCLUSIONS: Tubeless PCNL with externalized ureteral catheter is as feasible as Double-J stenting. Moreover, stent-related discomforts because of the presence of a Double-J stent and the need for postoperative cystoscopy to remove the Double-J stent can be avoided with an externalized ureteral catheter.

RESUMO

INTRODUCTION: In this study, we aimed to evaluate changes in contractile responses under in vitro conditions in detrusor overactivity (DO) in patients with bladder outflow obstruction (BOO). MATERIALS AND METHODS: Detrusor strips obtained during open prostatectomy procedure from 16 patients with BOO related to benign prostate hyperplasia were evaluated under in vitro conditions. Patients were assigned to two groups as patients with (DO) and without (no DO) DO. Four detrusor strips were prepared from each bladder in dimensions of 2 x 10 mm, and were suspended in organ bath. Responses to carbachol (10(-8) to 10(-3)M), electrical field stimulation (EFS) (0.5-32 Hz), single-dose adenosine 5'-triphosphate (ATP) (10(-3)M) and KCl (120 mM) were recorded to evaluate the contractile responses. EFS responses were repeated in the presence of NG-nitro-L-arginine methyl ester (L-NAME; 10 muM) and L-NAME + indomethacin. All responses were expressed as mg tension developed per mg of bladder tissue. Data obtained were compared using independent t test and one-way ANOVA test. Values of p < 0.05 were accepted as statistically significant. RESULTS: Of the 16 patients on whom open prostatectomy was performed because of BOO, 8 of the patients were determined as no DO and 8 as DO. There were no differences between groups regarding age and residual urine. We found statistically significant differences between groups regarding dimensions of prostate, maximum bladder capacity and maximum bladder pressure. In the comparison of cumulative dose of carbachol, it was seen that responses were higher in the DO group, but the differences were not statistically significant. In EFS application, contractile responses were found to increase significantly in the DO group. No changes were observed between groups for ATP and KCl. EFS responses were found to be significantly higher in presence of L-NAME + indomethacin in the no DO group; however, no difference was seen in the DO group. CONCLUSIONS: Detrusor contractile responses to EFS increased in patients with BOO in presence of overactivity. These changes in contractile responses are observed possibly as a result of deterioration in neuromodulation, rather than as a result of changes in purinergic or cholinergic receptor sensation or level. We suggest that a noncholinergic-nonpurinergic mechanism can have some effect on these changes.

RESUMO

BACKGROUND: The aim of this study was to compare results of the determination of carcinoembryonic antigen, carbohydrate antigens, alpha-fetoprotein, and human chorionic gonadotropin before and after surgical and pharmacologic treatment in patients with cystic echinococcosis (CE). METHODS: Serum samples were obtained from 40 CE patients (all with cysts in the liver) and from 10 sex- and age-matched healthy donors (control group). Serum samples were drawn (1) before (presurgical group) and after (postsurgical group, including a 3-month cycle of albendazole) surgical and pharmacologic treatment. Serum tumor markers were measured, and indirect hemagglutination assay was performed. RESULTS: In 90% of confirmed cases of CE, indirect hemagglutination assay was positive. Mean (SD) serum CA19-9 concentrations for all patients in the presurgical and postsurgical groups were 45.1 +/- 30 kU/L and 17.02 +/- 11 kU/L, respectively. CA19-9 concentrations were significantly greater in CE patients in the presurgical compared with the control group. Also, increased CA19-9 concentrations decreased significantly in the postsurgical compared with the presurgical group. CONCLUSIONS: A significant decrease in serum CA19-9 concentrations after surgical and pharmacologic therapy was demonstrated in the clinical follow-up of patients with CE (patients were tested 3 months after surgery). If our findings are confirmed and more-sensitive methods are developed for measuring serum CA19-9 concentrations, new and interesting perspectives will be gained for the monitoring and treatment of patients with CE.

RESUMO

Suture materials are widely used in urological surgery especially in regions that are in contact with urine. In this study, we aimed to compare polyglactine 910, chromed catgut and polydioxanone sutures according to stone formation and inflammation, congestion and foreign body reaction that occur on bladder mucosa. Cystotomy procedure was performed, in three groups of Wistar female rats, with 4/0 polyglactine 910, 4/0 chromed catgut and 4/0 polydioxanone sutures. All groups were divided into two sub-groups with 4 and 8-week follow up periods. Rats were treated with 20 mg kg(-1) day(-1) Ofloxacin (i.p.) daily until the seventh post-operative day. Urinary pH, leucocyte esterase and nitrite levels were determined. All rats were killed at the end of the follow-up period and stone formation on sutures and degrees of tissue reactions (inflammation, congestion and foreign body reaction) on bladder mucosa were compared. Tissue reactions were evaluated by the same pathologist (S. K.). Chi-square and Student's t test were used in statistical analysis (p<0.05). There was no significant difference between the mean weights of the groups. Leucocyte esterase and nitrite were negative in urine analyses. There was no significant difference between urinary pH levels of the groups with 4 and 8 weeks follow-up (p>0.05). Although the difference between the degrees of congestion in groups was not statistically significant (p>0.05), there were statistically significant differences between the degrees of inflammation and foreign body reaction in groups. Although the duration of urinary contact of suture is the main factor in stone formation on suture material, tissue reaction on mucosa and the physical structure of suture also affect this formation. We observed lower degrees of inflammation and foreign body reaction with 4/0 polydioxanone and no stone formation. We believe that polydioxanone may be useful and reliable in urological surgery due to these properties.

RESUMO

OBJECTIVE: Transrectal ultrasound (TRUS) guided prostate biopsy is well tolerated by patients but the lack of an effective marker to predict pain prevents us from determining pre-procedurally which patient group needs local anesthesia for biopsy and probe pain. Thus in this study, we investigated predictor factors for prostate biopsy and probe insertion pain. MATERIALS AND METHODS: 71 patients who were undergoing prostate biopsy without anesthesia were included in the study retrospectively. Pain had been assessed with visual analogue scale (VAS 0-10). Digital rectal examination (DRE) pain was analyzed for biopsy and probe insertion pain. RESULTS: DRE pain was related to both probe pain and biopsy pain. CONCLUSION: Although level of pain during DRE determines patients in need of local anesthesia, since the number of patients with moderate-severe pain is rather big, it seems efficient in determining the patients in need of additional anesthesia due to probe pain.

RESUMO

INTRODUCTION: The aim of this study was to compare age, prostatic volume, International Prostate Symptom Score (IPSS), maximal flow rate, serum total prostate-specific antigen (PSA), serum free PSA, free/total PSA ratio and PSA density values of familial and sporadic benign prostatic hyperplasia (BPH) patients suffering moderate or severe lower urinary tract symptoms. MATERIALS AND METHODS: Between September 1999 and August 2004, 511 patients with moderate or severe lower urinary tract symptoms (IPSS > or =8) due to BPH were included in the study. Patients with at least 2 first-degree relatives who had undergone surgery or received medication for BPH were classified as having the familial form of the disease, while the remaining patients were taken as sporadic cases. Mean age, prostatic volume, symptom score, maximal flow rate, PSA, free PSA, free/total PSA ratio and PSA density values of the familial and sporadic groups were compared using student's t test. RESULTS: Thirty-eight patients had a positive family history and formed the familial group, while the remaining 473 made up the sporadic group. No significant difference was observed in the parameters studied, except that mean prostate volume of the familial group was found to be greater and the mean age to be lower than those of sporadic patients in accordance with the literature. CONCLUSIONS: Patients with familial BPH need treatment significantly earlier and have larger prostates than those with sporadic BPH.
