Efficacy and Tolerability of Solifenacin 5 mg Fixed Dose in Korean Children with Newly Diagnosed Idiopathic Overactive Bladder: a Multicenter Prospective Study

We investigated the efficacy and tolerability of solifenacin 5 mg fixed dose in children with newly diagnosed idiopathic overactive bladder (OAB). A total of 34 children (male/female patients = 16/18) aged under 13 years (mean age: 7.2 ± 2.3; range: 5–12) who were newly diagnosed with OAB from January 2012 to September 2014 were prospectively evaluated with open-label protocol. All patients were treated with solifenacin 5 mg fixed dose once daily for at least 4 weeks. The efficacy and tolerability of solifenacin were evaluated 4, 8, and 12 weeks after the initiation of treatment. The mean voiding frequency during daytime was decreased from 9.4 ± 3.0 to 6.5 ± 2.3 times after the 12-week treatment (P < 0.001). The mean total OAB symptom score (OABSS) decreased from 7.7 ± 4.2 to 3.1 ± 3.1 after the 12-week treatment (P < 0.001). The urgency and urgency urinary incontinence (UUI) domains significantly improved from the 12-week treatment, and complete resolution of urgency occurred in 38.9% of patients and the percentage of children with UUI among urgent patients decreased from 79.4% to 57.1%. According to 3-day voiding diaries, the average bladder capacity increased from 90.4 ± 44.4 to 156.2 ± 67.3 mL (P < 0.001). Drug-induced adverse effects (AEs) were reported in 7 patients (20.6%). Our results indicate that solifenacin 5 mg fixed dose is effective against OAB symptoms, and its tolerability is acceptable without significant AEs in children with OAB.

Influence of Daytime or Nighttime Dosing with Solifenacin for Overactive Bladder with Nocturia: Impact on Nocturia and Sleep Quality

We compared changes in nocturia and sleep-related parameters between daytime and nighttime solifenacin dosing in patents with overactive bladder (OAB) and nocturia. We comparatively analyzed the data of a 12-week prospective, open-label, multicenter, randomized study. All 127 patients who presented to 5 centers in Korea for the treatment of OAB with nocturia between January 2011 and December 2013 were enrolled in this study. The patients were divided into 2 groups by medication timing: group 1, daytime (n = 62); and group 2, nighttime (n = 65). The International Prostate Symptom Score (IPSS), Overactive Bladder Symptom Score (OABSS), and Athens Insomnia Scale (AIS) were used to assess OAB symptoms and sleep quality. We evaluated the parameter changes before and 12 weeks after daytime or nighttime solifenacin administration. Baseline data, which included sex, age, body mass index (BMI), total AIS, IPSS, and OABSS, did not differ between the 2 groups. Total IPSS, OABSS, and total AIS significantly improved after solifenacin administration regardless of timing (P < 0.001). After solifenacin administration, the number of nocturia episodes decreased in the group 1 and 2 (P < 0.001). There were no significant intergroup differences in changes in AIS, IPSS, OABSS, and number of nocturia episodes 12 weeks after solifenacin administration. Treating OAB with solifenacin may improve nocturia and sleep quality, but advantages did not differ significantly by medication timing.

The Change of Stretched Penile Length and Anthropometric Data in Korean Children Aged 0-14 Years: Comparative Study of Last 25 Years

There has been a great improvement in height and weight of Korean children owing to economic development over the last 25 years. This study aimed to evaluate the penile length of Korean children today and to compare it with a previous Korean study reported in 1987. The cross-sectional study was conducted with 909 Korean boys aged 0-14 years who had been brought to outpatient clinics of five tertiary hospitals (Busan, Ulsan, and Changwon) between September 2013 and May 2015. The stretched penile length (SPL) was measured and the testicular size was measured using orchidometry (mL). Student's t-test or Mann-Whitney U test was used to compare the result of our study and the study reported in 1987. SPL of Korean children gradually increased from 4.1 ± 0.8 cm at 0-1 year old to 9.6 ± 3.0 cm at 13-14 years old, the most rapidly during the age of 13. While body weight and testicular size significantly increased from 1987 in most of age groups, there were no significant changes in SPL although there was in some age groups. Height decreased in the infants 6 years old. With the great economic development over the last quarter century in Korea, height, body weight, and testicular size of children significantly increased but there was no significant change in SPL except penile growth pattern.

Erratum: Efficacy and Tolerability of Anticholinergics in Korean Children with Overactive Bladder: A Multicenter Retrospective Study

We made a mistake in our recently published article.

Efficacy and Tolerability of Anticholinergics in Korean Children with Overactive Bladder: A Multicenter Retrospective Study

We investigated the efficacy and tolerability of various anticholinergics in Korean children with non-neurogenic overactive bladder (OAB). A total of 326 children (males:females= 157:169) aged under 18 yr (mean age 7.3+/-2.6 yr) who were diagnosed with OAB from 2008 to 2011 were retrospectively reviewed. The mean duration of OAB symptoms before anticholinergic treatment was 16.9+/-19.0 months. The mean duration of medication was 5.6+/-7.3 months. Urgency urinary incontinence episodes per week decreased from 1.9+/-3.1 to 0.4+/-1.5 times (P<0.001). The median voiding frequency during daytime was decreased from 9.2+/-5.4 to 6.3+/-4.2 times (P<0.001). According to 3-day voiding diaries, the maximum and average bladder capacity were increased from 145.5+/-66.9 to 196.8+/-80.3 mL and from 80.8+/-39.6 to 121.8+/-56.5 mL, respectively (P<0.001). On uroflowmetry, maximum flow rate was increased from 17.6+/-8.4 to 20.5+/-8.2 mL/sec (P<0.001). Adverse effects were reported in 14 (4.3%) children and six children (1.8%) discontinued medication due to adverse effects. Our results indicate that anticholinergics are effective to improve OAB symptoms and tolerability was acceptable without severe complications in children.

Interfraction Prostate Movement in Bone Alignment After Rectal Enema for Radiotherapy

PURPOSE: To assess the effect of a rectal enema on interfraction prostate movement in bone alignment (BA) for prostate radiotherapy (RT), we analyzed the spatial difference in prostates in a bone-matched setup. MATERIALS AND METHODS: We performed BA retrospectively with data from prostate cancer patients who underwent image-guided RT (IGRT). The prostate was identified with implanted fiducial markers. The setup for the IGRT was conducted with the matching of three fiducial markers on RT planning computed tomography images and those on two oblique kV x-ray images. Offline BA was performed at the same position. The coordinates of a virtual prostate in BA and a real prostate were obtained by use of the ExaxTrac/NovalisBody system, and the distance between them was calculated as the spatial difference. Interfraction prostate displacement was drawn from the comparison of the spatial differences. RESULTS: A total of 15 patients with localized prostate cancer treated with curative hypofractionated IGRT were enrolled. A total of 420 fractions were analyzed. The mean of the interfraction prostate displacements after BA was 3.12+/-2.00 mm (range, 0.20-10.53 mm). The directional difference was profound in the anterior-posterior and supero-inferior directions (2.14+/-1.73 mm and 1.97+/-1.44 mm, respectively) compared with the right-left direction (0.26+/-0.22 mm, p<0.05). The required margin around the clinical target volume was 4.97 mm with the formula of van Herk et al. CONCLUSIONS: The interfraction prostate displacement was less frequent when a rectal enema was performed before the procedure. A rectal enema can be used to reduce interfraction prostate displacement and resulting clinical target volume-to-planning target volume margin.

Efficacy of Extracorporeal Shock Wave Lithotripsy in Pediatric and Adolescent Urolithiasis

PURPOSE: To retrospectively evaluate the efficacy of extracorporeal shock wave lithotripsy (ESWL) by age and current condition as a first-line treatment for pediatric and adolescent urolithiasis. MATERIALS AND METHODS: The computerized records of 55 children were retrospectively reviewed from March 1991 to July 2007. The children were below 18 years of age and had undergone ESWL monotherapy for urolithiasis. There were 36 boys (65.5%) and 19 girls (34.5%), with a mean age of 8.5 years (range, 0.5-18 years). There were 24 patients aged 7 years or less and 31 patients aged more than 7 years. RESULTS: The mean size of the stones was 9.48 mm (range, 4-22 mm). The overall success rate of ESWL was 90.9% (50 children). The mean number of ESWL sessions was 2.02 (range, 1-10). The mean number of ESWL sessions for the patient group aged 7 years or less was 1.16 (range, 1-2) and that for the patient group aged more than 7 years was 2.97 (range, 1-10; p=0.037). There was also a statistically significant difference in the mean number of ESWL sessions between the younger and older patients who needed general anesthesia (1.16 vs. 2.2 sessions, respectively; 0.042). CONCLUSIONS: In the patient group aged 7 years or less, the number of ESWL sessions and the complication rate were comparable with those for endoscopic management. Thus, ESWL is an effective first-line treatment modality for patients aged less than 7 years.

A Boy with Adrenocortical Tumor Who Progressed to Central Precocious Puberty after Surgery

Adrenocortical tumors in children are rare and show various clinical symptoms. We present an 8-year-old boy with peripheral precocious puberty caused by adrenocortical tumor. He showed elevated serum DHEA-S and 17-hydroxyprogesterone, and computed tomography revealed an abdominal mass. After surgical resection, he developed central precocious puberty. We report a rare case that showed progression from peripheral precocious puberty to central precocious puberty.

Tamsulosin Monotherapy versus Combination Therapy with Antibiotics or Anti-Inflammatory Agents in the Treatment of Chronic Pelvic Pain Syndrome / 대한배뇨장애요실금학회지

PURPOSE: Chronic pelvic pain syndrome (CPPS) is treated by use of various protocols. We compared tamsulosin monotherapy with tamsulosin in combination with antibiotics or anti-inflammatory agents and evaluated the efficacy of these treatments in patients with CPPS. METHODS: Patients (n=107) who were younger than 55 years and diagnosed with CPPS were randomly assigned to treatment with tamsulosin at 0.2 mg (group A), tamsulosin at 0.2 mg plus anti-inflammatory drugs (group B) or tamsulosin at 0.2 mg plus antibiotics (group C) daily. We applied the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) and the International Prostate Symptom Score (IPSS) to evaluate 100 patients who were treated for 12 weeks (7 withdrew). Scores of the three groups were compared by analysis of variance and we also evaluated subscores, which included pain, voiding and quality of life (QoL). RESULTS: All three groups showed statistically significant decreases in NIH-CPSI score, IPSS and subscore scores (P<0.05). There were no statistically significant differences between the groups except for the QoL domain of the IPSS (group A vs. C; P<0.01). CONCLUSIONS: Tamsulosin monotherapy for 12 weeks was effective for treating patients with CPPS, compared with combination therapy with antibiotics or anti-inflammatory drugs.

Effect of Tamsulosin 0.2 mg on the Short-Term Treatment of Urinary Stones: Multicenter, Prospective, Randomized Study

PURPOSE: We evaluated the effect of tamsulosin for the short-term treatment of urinary stones. MATERIALS AND METHODS: Two hundred forty-seven patients who were diagnosed with urinary stones were enrolled in this prospective, randomized multicenter study. The treatment and extracorporeal shock wave lithotripsy (ESWL) group (Group 1, n=115) was given diclofenac sodium 100 mg plus tamsulosin 0.2 mg for 1 week. The control and SWL group (Group 2, n=92) was given diclofenac sodium for 1 week. The treatment and no SWL group (Group 3, n=19) was treated the same as Group 1. The control and no SWL group (Group 4, n=21) was given diclofenac sodium only. Patients in Groups 3 and 4 did not want to take SWL treatment. The size of the stone, expulsion rate according to stone location and ESWL machines, changes in pain score, and distance of stone migration when expulsion of the stone failed were compared among the groups. RESULTS: There were no differences in the 4 groups in sex or stone size. The stone expulsion rate of lower ureter stones in group 1 (59.6%) was significantly higher than in group 2 (30.8%) (p=0.01). The distance of stone migration in group 3 was longer than that in group 4 (5.63+/-5.48 cm compared with 0.33+/-0.68 cm; p=0.002). Although the difference was not significant in the SWL groups, the distance of stone migration in group 1 was longer than that in group 2 (7.08+/-6.9 cm compared with 5.46+/-7.4 cm; p>0.05). There were no significant differences in changes on the pain scale among the groups. CONCLUSIONS: These results suggest that adjunctive medical therapy for 1 week with tamsulosin after SWL increases the stone expulsion rate of lower ureteral stones and increases the distance of stone migration in case of failure of stone expulsion.

Comparison of Techniques for Laparoscopic Radical Nephrectomy in a Single Center: Transperitoneal vs. Retroperitoneal vs. Hand-Assisted

PURPOSE: Laparoscopic surgery has become the standard method of radical nephrectomy within the urological community. We compared the safety and efficacy of different techniques for laparoscopic radical nephrectomy (LRN) in a single medical center. MATERIALS AND METHODS: Between June 2002 and August 2007, we performed LRN for renal cell cancer in 45 cases by a transperitoneal approach (TLRN), in 21 cases by a retroperitoneal approach (RLRN), and in 32 cases by a hand-assisted approach (HLRN), and the results of each approach were compared. Surgical results such as operative time, estimated blood loss (EBL), transfusion rate, hospital stay, complications, and pathologic results were reviewed retrospectively and analyzed by one-way ANOVA. RESULTS: There were no significant differences in demographic data among the 3 groups. The pathologic reports showed clear cell type in 97 cases and chromophobe type in 1 case. For each group (TLRN vs. RLRN vs. HLRN), the mean operative time was 207.9+/-57.06 vs. 211.8+/-52.85 vs. 184.4+/-49.43 minutes, respectively (p=0.03); the EBL was 135.0+/-29.40 vs. 153.8+/-45.59 vs. 183.4+/-89.25 ml, respectively (p=0.14); time to oral intake was 2.3+/-0.79 vs. 1.2+/-0.54 vs. 2.6+/-0.84 days, respectively (p<0.01); and the hospital stay was 6.7+/-0.77 vs. 5.4+/-0.73 vs. 8.2+/-1.51 days, respectively (p<0.01). There were no severe complications. The pathologic surgical margins were all negative. CONCLUSIONS: LRN can be performed efficiently and effectively with the transperitoneal, retroperitoneal, and hand-assisted techniques. Operators may select the technique for LRN according to their own preferences. In our experience, RLRN may protect the organ from injury and promote the recovery of lifestyle because of the early recovery of bowel movement.

The Prevalence and Management of Urinary Incontinence in Elderly Patients at Sanatorium in Busan Area

PURPOSE: Prevalence estimates and management methods for urinary incontinence among elderly patients aged 65 and over at sanatoriums in Busan area were investigated. MATERIALS AND METHODS: A sample of 834 institutionalized patients was randomly selected from 13 sanatoriums with 100 and more beds in Busan. The study was designed as a cross-sectional study. Data were collected via face-to-face interviews using Appendix about general status, obstetric history, incontinence, and management method for incontinence. The survey was conducted from February to September 2008. RESULTS: Overall prevalence of urinary incontinence in all of 834 respondents was found to be 48.1%: prevalences of stress incontinence, urge incontinence, mixed incontinence, and functional incontinence were 25.7%, 6.5%, 8.0% and 59.9%, respectively. Among the patients with urinary incontinence symptoms, 28.6% had associated-dermatologic problems. CONCLUSIONS: The estimated prevalence of incontinence for elderly patients aged 65 and more cared at Sanatoriums in Busan area was 48.1%. However, systemic approaches in the management of urinary incontinence in such patients were lacking. Further efforts should be made for proper management of urinary incontinence among elderly patients cared at Sanatorium.

The Change of Cognitive Function after Administration of Tolterodine in Brain Disease Patients with Overactive Bladder

PUROPOSE: It is known that anticholinergics induces cognitive dysfunction and may aggravate the state of it. Tolterodine tartrate (detrusitol(R)) is a widely known selective anticholinergics to bladder, which does not cause a cognitive dysfunction. This study was designed to analyze the change of cognitive function of brain disease patients, whom are taking anticholinesterase inhibitor with tolterodine for overactive bladder (OAB). MATERIAL AND METHODS: From January 2001 to December 2004, with the patients whom have been followed for the brain disease in the department of neurology, we have analyzed 79 patients with tolterodine administered for OAB. We used K-MMSE (Korea minimental status examination) and SNSB (seoul neuropsychological screening battery) to analyze the state of cognition. Mean age of patients was 67.3+/-4.5 (yrs), mean administration period was 4.7+/-9.5 (mon). RESULTS: 7 patients made complaints for the decline of memory, 2 of them with Parkinsonism and 2 with cerebral infarction, 1 with progressive supranuclear palsy and, 2 dementia with lewy body (DLB). Patients with DLB was excluded in this study because the disease had fluctuation of cognitive function. CONCLUSIONS: The result of these studies demonstrates tolterodine tartrate caused the decline of cognitive function in only a few patients with brain disease. We concluded that prospective studies are needed to change the cognitive functions of the brain disease patients with OAB after administration of tolterodine tartrate.

The Prevalence and Risk Factors of Overactive Bladder in Korean Children: A Comparative Analysis according to Definition / 대한비뇨기과학회지

PURPOSE: We wanted to estimate the prevalence and risk factors of overactive bladder(OAB) in Korean children who were 5-13 years of age, according to the definition of OAB. MATERIALS AND METHODS: A randomly selected cross-sectional study was conducted on 26 kindergartens and 27 elementary schools nationwide in Korea. There were 19,240 children; a parent was asked to complete the questionnaires, which included items about OAB and the children's voiding and defecating habits. OAB was defined as urgency with or without urge incontinence, and usually with an increased daytime frequency and nocturia(ICCS 2006, group A) or an increased daytime frequency(>8 times/day) and/or urge urinary incontinence with or without urgency (group B); its prevalence and associated factors were investigated. RESULTS: The response rate for the questionnaires was 85.84%. The overall prevalence of OAB was 16.59%(group A) and 18.79%(group B). For groups A and B, the prevalence of OAB decreased with age from 22.89% to 12.16% and from 40.44% to 9.60%, respectively(p=0.0001). The overall rate of wet and dry OAB was 26.97% and 73.03%, respectively. Compared to the normal group, the children with OAB had a higher prevalence of nocturnal enuresis(NE), constipation, fecal incontinence, a history of urinary tract infection and delayed bladder control in both groups A and B(p<0.05). The rate of increased daytime frequency and urge incontinence were 3.69% and 2.31%(p=0.009), and 26.97% and 14.78%(p=0.0001) in group A and for the non-OAB children, respectively; their prevalence in group A decreased with age from 5.04% to 3.06% and from 45.74% to 18.50%, respectively(p=0.0001). CONCLUSIONS: The overall prevalence of OAB in group A for Korean children 5-13 years of age was similar to that in group B. However, the range of prevalence in group B was much more variable than that in group A. NE, constipation, fecal incontinence, a history of urinary tract infection and delayed bladder control may be risk factors for OAB in children.

Unusual Metastasis in Renal Cell Carcinoma / 대한비뇨기과학회지

Approximately one-third of all patients with renal cell carcinoma have metastasis at the time of diagnosis. Metastatic lesions of renal cell carcinoma are most commonly seen in the lung, and they are frequently seen in the bone and liver. However, spleen and rectal metastases are extremely rare. A 63-year-old man had undergone left radical nephrectomy for renal cell carcinoma. About 22 months later, computed tomography revealed multiple enhanced masses in the spleen. Spleen metastasis was suspected and splenectomy was then performed. One year later, the patient visited with complaints of voiding difficulty. A huge pelvic mass was detected by performing prostate ultrasonography and MRI. The mass was 13cm in diameter and it was between the rectum and the prostate. Removal of the pelvic mass and lower anterior resection with end colostomy was done. Histologically, the resected specimens were diagnosed as metastases from the renal cell cancer. Herein, we report on a case of metachronous splenic and rectal metastasis from renal cell carcinoma.

Comparison of Laparoscopic Radical Nephrectomy with Open Radical Nephrectomy / 대한비뇨기과학회지

PURPOSE: Laparoscopic surgery has become the standard surgical method within the urological community. This study was undertaken to evaluate the safety and efficacy of a standard laparoscopic radical nephrectomy (LRN) compared to an open radical nephrectomy (ORN) at a single medical center. MATERIALS AND METHODS: Between January 2003 and March 2006, laparoscopic radical nephrectomies for renal cell cancer were performed in 30 patients and the results of the laparoscopic radical nephrectomy were compared with those of the open counterpart. Surgical results, such as the operation time, estimated blood loss (EBL), transfusion rate, narcotic analgesic requirement, hospital stay, complications and pathologic results, were retrospectively reviewed and analyzed using the Student's t-test. RESULTS: There were no significant differences in the demographic data between the two groups. The pathological reports showed a clear cell type in 59 cases and a chromophobe type in 1 case. For the LRN and ORN groups, the mean operation times were 208 (120-320) vs. 206 min. (115-300) (p>0.05), EBL of 135 (100-200) vs. 318ml (100-2,000) (p=0.02), transfusion rates of 6.6 vs. 30%, narcotic analgesic requirements of 160 vs. 255mg diclofenac sodium, hospital stays of 6.7 vs. 10.5 days (p=0.04) and intraoperative complications in 0/30 (0%) vs. 2/30 cases (7%), respectively. The pathological surgical margins were all negative. The surgical and pathological parameters of the LRN group showed no significant differences to those of the ORN group, with the exception of the EBL and hospital stay. CONCLUSIONS: Laparoscopic radical nephrectomy resulted in less blood loss, a shorter hospital stay and earlier rapid recovery than an open radical nephrectomy. In our opinion, laparoscopic surgery could be a standard surgical treatment in renal cell cancer.

Fibrous Pseudotumor in the Testicular Tunica / 대한비뇨기과학회지

Fibrous pseudotumor of the testicular tunics is uncommon lesion. They typically arise as painless scrotal masses that may be associated with a hydrocele or history of trauma or infection. Two-thirds involve the tunica vaginalis testis, with infrequent involvement of other scrotal structures. Once excised, these lesions behave in a benign fashion. Typically, these masses are multinodular, but in rare cases they are diffuse, band-like myofibroblastic proliferations that encase the testis. We report here on a case of fibrous pseudotumor of the tunica vaginalis in 76 year-old patient. (Korean J Urol 2006;47:1130-1132)

Behavioral and Emotional Problems in Children with Nocturnal Enuresis: Results of a Multicenter Study / 신경정신의학

OBJECTIVES: The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. METHODS: Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. RESULTS: Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. CONCLUSION: The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

Development of Laparoscopic Training Protocol Using Small Animal Model in Urology / 대한비뇨기과학회지

PURPOSE: Laparoscopy is a standard treatment for many diseases. We developed a laparoscopy training protocol that provides a learning experience equivalent to that of an animal laboratory based laparoscopic training course. We proved that the rabbit can be used as an appropriate model for a laparoscopy training program. MATERIALS AND METHODS: Three operators undertook laparoscopic procedures on 15 rabbits using our developed protocol. We checked both objective and subjective parameters, such as operation times and complications for the former, and hand-eye coordination, tactile sensation, tool handling and total skill difficulty for the later, using visual analogue scores. RESULTS: For the first 5 rabbits, the mean operative times (min.) for the 3 operators were 41, 48 and 46.2 for a simple nephrectomy (SN), 62, 68.2 and 66.2 for a partial nephrectomy (PN), 28.8, 36 and 31.8 for an adrenalectomy (Ax) and 65.4, 69 and 60.6 for a simple cystectomy (SC). For the second 5 rabbits the mean operative times (min.) were; SN 32.2, 46.2 and 40.2, PN 57.8, 66.2 and 61.8, Ax 22.8, 32.6 and 32 and SC 65.4, 64.2 and 57.4. For all 15 rabbits the mean operative times (min.) were; SN 20.6, 35.4 and 30, PN 48.6, 54.6 and 53.4, Ax 15.8, 26.2 and 26.2 and CS 48.2, 53.6 and 47.6. CONCLUSIONS: Our laparoscopic training model, using a small animal, provides practicing urologist with the concepts of laparoscopy concept. The rabbit model is appropriate for addressing laparoscopic procedures, with economic benefits. Based on this model, it would be possible for residents to familiarize themselves with laparoscopic procedures.

Laparoscopic Excision of a Seminal Vesicle Cysts Associated with Ipsilateral Renal Agenesis / 대한비뇨기과학회지

A case of seminal vesicle cysts with ipsilateral renal agenesis is uncommon. An excision of a seminal vesicle cyst was successfully performed using a transperitoneal laparoscopic approach in 27-year-old male affected by recurrent perineal discomfort and post-ejaculatory pain. The operative time and blood loss were 85 minutes and 50ml, respectively. No postoperative complications were noted, and the patient discharged on the 5th postoperative day. Laparoscopic excision of seminal vesicle cystic disease is an effective surgical procedure, with excellent intraoperative access and minimal postoperative morbidity.
