Practice Patterns of Korean Urologists Regarding Positive Surgical Margins after Radical Prostatectomy: a Survey and Narrative Review

Background@#There is no clear consensus on the optimal treatment with curative intent for patients with positive surgical margins (PSMs) following radical prostatectomy (RP). The aim of this study was to investigate the perceptions and treatment patterns of Korean urologists regarding the resection margin after RP. @*Methods@#A preliminary questionnaire was prepared by analyzing various studies on resection margins after RP. Eight experienced urologists finalized the 10-item questionnaire.In July 2019, the final questionnaire was delivered via e-mail to 105 urologists in Korea who specialize in urinary cancers. @*Results@#We received replies from 91 of the 105 urologists (86.7%) in our sample population.Among them, 41 respondents (45.1%) had performed more than 300 RPs and 22 (24.2%) had completed 500 or more RPs. In the question about whether they usually performed an additional biopsy beyond the main specimen, to get information about surgical margin invasion during surgery, the main opinion was that if no residual cancer was suspected, it was not performed (74.7%). For PSMs, the Gleason score of the positive site (49.5%) was judged to be a more important prognostic factor than the margin location (18.7%), multifocality (14.3%), or margin length (17.6%). In cases with PSMs after surgery, the prevailing opinion on follow-up was to measure and monitor prostate-specific antigen (PSA) levels rather than to begin immediate treatment (68.1%). Many respondents said that they considered postoperative radiologic examinations when PSA was elevated (72.2%), rather than regularly (24.4%). When patients had PSMs without extracapsular extension (pT2R1) or a negative surgical margin with extracapsular extension (pT3aR0), the response ‘does not make a difference in treatment policy’ prevailed at 65.9%. Even in patients at high risk of PSMs on preoperative radiologic screening, 84.6% of the respondents said that they did not perform neoadjuvant androgen deprivation therapy. Most respondents (75.8%) indicated that they avoided nerve-sparing RP in cases with a high risk of PSMs, but 25.7% said that they had tried nerve-sparing surgery. Additional analyses showed that urologists who had performed 300 or more prostatectomies tended to attempt more nerve-sparing procedures in patients with a high risk of PSMs than less experienced surgeons (36.6% vs. 14.0%; P = 0.012). @*Conclusion@#The most common response was to monitor PSA levels without recommending any additional treatment when PSMs were found after RP. Through this questionnaire, we found that the perceptions and treatment patterns of Korean urologists differed considerably according to RP resection margin status. Refined research and standard practice guidelines are needed.

Estramustine Phosphate Monotherapy in Castration-Resistant Prostate Cancer Patients Who Cannot Receive Cytotoxic Chemotherapy

Purpose@#To investigate whether estramustine phosphate (EMP) monotherapy is applicable to castration-resistantprostate cancer (CRPC) patients who cannot receive cytotoxic chemotherapy. @*Materials and Methods@#This retrospective single-arm study was conducted in CRPC patients who had notexperienced cytotoxic chemotherapy and received EMP monotherapy (560 mg/day) at 2 institutions from 2008to 2017. We analyzed prostate-specific antigen (PSA) responses, overall survival, and adverse effects of EMPtreatment. @*Results@#A total of 28 patients were analyzed. A reduction in serum PSA was observed in 11 patients (39.3%).Seven cases (25.9%) achieved more than 25% reduction of PSA, and 5 of them (18.5%) experienced more than50% reduction. Median overall survival was 23 months (interquartile range, 10–60 months). Multivariable analysesdemonstrated that low level of PSA at diagnosis of CRPC and long duration of prior androgen deprivation therapywere independent favorable factors predicting long-term overall survival. Adverse effects were edema (n=2; grade2), nausea/vomiting (n=1; grade 2), gynecomastia (n=1; grade 2), and dyspnea (n=1; grade 1). Neither thromboembolicevent nor grade 3–5 toxicity was observed. There was no discontinuation caused by side effects ofEMP. @*Conclusions@#EMP monotherapy could be considered as a safe treatment option with some effectiveness for CRPCpatients who did not undergo cytotoxic chemotherapy. EMP is not generally recommended anticancer drug in thecurrent guidelines for CRPC, but EMP monotherapy is thought to have an alternative role when a standard treatmentcannot be selected due to patient's age, health condition, or comorbidity.

Does the Time Interval from Biopsy to Radical Prostatectomy Affect the Postoperative Oncologic Outcomes in Korean Men?

BACKGROUND: Prostate cancer (PC) is the second most common type of cancer in men worldwide and the fifth most common cancer among Korean men. Although most PCs grow slowly, it is unclear whether a longer time interval from diagnosis to treatment causes worse outcomes. This study aimed to investigate whether the time interval from diagnosis to radical prostatectomy (RP) in men with clinically localized PC affects postoperative oncologic outcomes. METHODS: We retrospectively analyzed data of 427 men who underwent RP for localized PC between January 2005 and June 2016. The patients were divided into two groups based on the cutoff median time interval (100 days) from biopsy to surgery. The associations between time interval from biopsy to surgery (< 100 vs. ≥ 100 days) and adverse pathologic outcomes such as positive surgical margin, pathologic upgrading, and upstaging were evaluated. Biochemical recurrence (BCR)-free survival rates were analyzed and compared based on the time interval from biopsy to surgery. RESULTS: Pathologic upgrading of Gleason score in surgical specimens was more frequent in the longer time interval group and showed marginal significance (38.8% vs. 30.0%; P = 0.057). Based on multivariable analysis, an association was observed between time interval from biopsy to surgery and pathologic upgrading (odds ratio, 2.211; 95% confidence interval [CI], 1.342–3.645; P = 0.002). BCR-free survival did not differ based on time interval from biopsy to surgery, and significant association was not observed between time interval from biopsy to surgery and BCR on multivariable analysis (hazard ratio, 1.285; 95% CI, 0.795–2.077; P = 0.305). CONCLUSION: Time interval ≥ 100 days from biopsy to RP in clinically localized PC increased the risk of pathologic upgrading but did not affect long-term BCR-free survival rates in Korean men.

Long-Lasting Antiandrogen Withdrawal Syndrome in Castration-Resistant Prostate Cancer: Three Cases With Complete Response

This is a case report of 3 patients who had a dramatic and long-term complete response after antiandrogen withdrawal. All 3 patients were diagnosed with advanced or metastatic prostate cancer with a high prostate-specific antigen (PSA) level. For all patients, we started combined androgen blockade as androgen deprivation therapy and the PSA concentration decreased to <0.1 ng/mL, but then started to increase. After discontinuation of antiandrogen the PSA concentration decreased again and has remained below the limit of sensitivity for more than 1 year in all 3 patients.

Radical Prostatectomy in Korean Men Aged 75-Years or Older: Safety and Efficacy in Comparison with Patients Aged 65-69 Years

Prostate cancer is the most common type of male cancer worldwide. Although radical prostatectomy (RP) is advised for prostate cancer in patients with a life expectancy of more than 10 years by various guidelines, most elderly men still do not undergo the procedure regardless of increasing life expectancy. This study aimed to determine whether RP is suitable for patients with prostate cancer aged 75 years or older. A retrospective study of patients who underwent RP at 6 institutions between 2005 and 2012 was conducted. Patients were divided into 2 groups at the time of surgery: 65-69 years (younger group) and 75 years or older (older group). We compared clinical characteristics, pathological results, complication rates, and recurrence-free survival between the two groups. Compared with the younger group, the older group had significantly higher preoperative serum prostate-specific antigen level, pre- and postoperative Eastern Cooperative Oncology Group (ECOG) performance status grade, hypertension prevalence, and Gleason score at biopsy and RP. However, except urinary incontinence, there were no statistically significant differences in the peri- and post-operative complications. After median follow-up periods of 36 months (younger group) and 40 months (older group), the biochemical recurrence-free survival rates were not significantly different (P = 0.581). Although the urinary incontinence rate was higher in the older group, RP was a suitable option for selected Korean men aged 75 years or older with limited complication rates and excellent outcomes similar to those for patients aged 65-69 years.

Climacturia (Orgasm-associated Incontinence) Following Radical Prostatectomy

PURPOSE: Climacturia is involuntary loss of urine during orgasm. The mechanism of climacturia in men who undergo radical prostatectomy (RP) is not fully understood, while deficiency in bladder neck coaptation during orgasm may be the cause. We evaluated the prevalence and risk factors of climacturia after RP. MATERIALS AND METHODS: We retrospectively reviewed the medical records of prostate cancer patients who underwent RP from 2002 to 2013 and was able to have a vaginal intercourse postoperatively. RP was conducted using open or robot-assisted approach. We analysed the symptoms of climacturia, relationship between climacturia and several clinical factors. Also, we tried to find factors to predict the presence of climacturia. RESULTS: Total of 123 patients were analyzed in this study. The median age of the men was 65 year and postoperative follow-up period for the interview was 37 months. Of the total 123 patients, 29 (23.6%) complained of the climacturia. In climacturia group, robot-assisted RP (p=0.018), nerve-sparing (p=0.046) and penile rehabilitation (p=0.012) were significantly less frequent, and more pad were comsumed (p=0.001) compared to non-climacturia group. On multivariable analysis, post-prostatectomy incontinence (PPI) (OR 6.49, p=0.004) and penile rehabilitation (OR 0.22, p=0.036) were significant factors to predict the presence of climacturia. CONCLUSIONS: Climacturia occurs in more than 20% patients who were potent enough after RP in our study. PPI and penile rehabilitation were positive and negative factor to predict an occurrence of climacturia, respectively. Therefore, in addition to PPI and erectile dysfunction, patients must be informed of this complication before undergoing RP.

Oncologic Outcomes of Patients With Gleason Score 7 and Tertiary Gleason Pattern 5 After Radical Prostatectomy

PURPOSE: We evaluated oncologic outcomes following radical prostatectomy (RP) in patients with a Gleason score (GS) of 7 with tertiary Gleason pattern 5 (TGP5). MATERIALS AND METHODS: We retrospectively reviewed the medical records of 310 patients who underwent RP from 2005 to 2010. Twenty-four patients who received neoadjuvant or adjuvant antiandrogen deprivation or radiation therapy were excluded. Just 239 (GS 6 to 8) of the remaining 286 patients were included in the study. Patients were classified into four groups: GS 6, GS 7 without TGP5, GS 7 with TGP5, and GS 8. We analyzed preoperative clinical factors, postoperative pathological outcomes, and biochemical recurrence (BCR). RESULTS: TGP5 in GS 7 was an independent predictor of primary Gleason pattern 4, tumor volume larger than 10%, positive surgical margin, and lymphovascular invasion. The presence of TGP5 in GS 7 was not associated with BCR-free survival. Subgroup analyses revealed that BCR-free survival did not differ significantly between patients with GS 7 with TGP5 and those with GS 8 (p=0.120). In addition, time to BCR in patients with a higher percentage of TGP5 was shorter than that in patients with a lower percentage of TGP5. TGP5 in GS 7 was not a significant predictive factor for BCR, whereas prostate-specific antigen density and a positive surgical margin were shown to be independent predictors of BCR. CONCLUSIONS: TGP5 in GS 7 was an independent predictor of unfavorable pathologic outcomes. The rate of BCR was similar in GS 7 disease with TGP5 and in GS 8 disease, even though TGP5 was not a significant predictive factor for BCR in Cox proportional hazards models.

Do Positive Surgical Margins Predict Biochemical Recurrence in All Patients Without Adjuvant Therapy After Radical Prostatectomy?

PURPOSE: The objective was to study whether positive surgical margins (PSMs) predict biochemical recurrence (BCR) in all patients without adjuvant therapy after radical prostatectomy (RP). MATERIALS AND METHODS: We retrospectively reviewed the medical records of patients who underwent RP for prostate cancer at Veterans Health Service Medical Center from 2005 to 2011. BCR was defined by a prostate-specific antigen (PSA) value > or =0.2 ng/mL. The clinicopathological factors of the PSM group were compared with those of the negative surgical margin (NSM) group, and the predictive impact of a PSM for BCR-free survival were evaluated. In addition, we analyzed the prognostic difference for BCR-free survival between solitary and multiple PSMs. RESULTS: A PSM was noted in 167 patients (45.5%). BCR was reported in 101 men in total (27.5%). The BCR-free survival rate of the PSM group was lower than that of the NSM group (p<0.001). In a multivariate analysis for the total patients, PSM was significantly associated with BCR-free survival (p<0.001). After stratification by pathological T stage, Gleason score (GS), and preoperative PSA value, PSM was significantly predictive for BCR-free survival in men with pT2 and/or GS < or =6 or 7 and/or a PSA value <10 or 10-20 ng/mL (all p<0.05). Multiple PSMs were more predictive of BCR-free survival than was a solitary PSM (p=0.001). CONCLUSIONS: A PSM is a significant predictor of postoperative BCR in patients with pT2 and/or GS < or =7 and/or preoperative PSA <20 ng/mL. Multiple PSMs are considered a stronger prognostic factor for prediction of BCR than is a solitary PSM.

Differences in Postoperative Pathological Outcomes between Prostate Cancers Diagnosed at Initial and Repeat Biopsy

PURPOSE: We evaluated the differences in pathological outcomes between prostate cancers (PCas) diagnosed at initial and repeat biopsy. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 287 patients who underwent radical retropubic prostatectomy from 2005 to 2010. We investigated preoperative factors, such as age, serum prostate-specific antigen (PSA), prostate volume (PV), digital rectal examination (DRE) results, biopsy schema, clinical stage, and number of prior biopsies, and postoperative pathological outcomes, including specimen volume, percent tumor volume, Gleason score (GS), tumor bilaterality, pathological stage, positive surgical margin (PSM), lymphovascular invasion (LVI), and perineural invasion (PNI). Patients were then classified into two groups by the number of prior biopsies (initial biopsy vs. repeat biopsy). We compared preoperative factors and postoperative pathological outcomes between the two groups. RESULTS: Of the 287 patients, 246 (85.7%) were diagnosed with cancer at the initial biopsy and 41 (14.3%) at the repeat biopsy. The repeat biopsy group was older (p=0.048), had a larger PV (p=0.009), had a significantly different biopsy schema (p<0.001), and had a lower (<10%) percentage tumor volume (p=0.016). In the multivariate analysis (after adjustment for biopsy schema, age, serum PSA, PV, and DRE), repeat biopsy was not an independent predictor of GS, tumor bilaterality, pathological stage, PSM, LVI, or PNI (p=0.212, 0.456, 0.459, 0.917, 0.991 and 0.827, respectively), but repeat biopsy could predict lower percentage tumor volume (p=0.037). CONCLUSIONS: The pathological outcomes of PCas detected at repeat biopsy were not significantly different from those of PCas detected at initial biopsy except for a lower (<10%) percentage tumor volume.

Results of Urine Culture and Antimicrobial Sensitivity Tests According to the Voiding Method Over 10 Years in Patients with Spinal Cord Injury

PURPOSE: We studied the results of urine cultures and antimicrobial sensitivity tests according to the voiding method used by spinal cord injury (SCI) patients over a recent 10-year period. MATERIALS AND METHODS: We retrospectively analyzed 1,236 urine samples and their antimicrobial sensitivity tests for 112 patients who had used only one voiding method between January 2000 and December 2009. The voiding methods were classified into four groups: clean intermittent catheterization (CIC), suprapubic catheterization, urethral Foley catheter, and spontaneous voiding. RESULTS: Of the 1,236 urine samples, 925 (74.8%) were positive and 279 (30.2%) had more than one bacteria. The CIC group showed the lowest rate of bacteriuria, colony counts, and polymicrobial infection (p<0.001). Causative organisms were mostly Gram-negative bacteria (84%), including Pseudomonas aeruginosa (22.9%), Escherichia coli (21.1%), Klebsiella species (6.7%), and Citrobacter species (6.3%). The rate of Gram-positive bacterial infection was 13.6%, and major pathogenic organisms were Streptococcus species (8.6%) and Staphylococcus species (2.6%). Major pathogenic organisms and the results of antimicrobial sensitivity tests differed according to the voiding method. CONCLUSIONS: Although the patient's condition and preferences are important when choosing the method of bladder management, CIC is the best voiding method for reducing urinary tract infections in SCI patients. When immediate use of antibiotics is needed for treatment of urinary tract infections, an appropriate antibiotic can be chosen according to the voiding method on the basis of our study and can be administered before the results of an antimicrobial sensitivity test are available.

Efficacy of Alternative Antiandrogen Therapy for Prostate Cancer That Relapsed after Initial Maximum Androgen Blockade

PURPOSE: We evaluated the effectiveness of second-line maximum androgen blockade (MAB) with an alternative antiandrogen in patients who relapsed after initial MAB. MATERIALS AND METHODS: We retrospectively analyzed 47 patients with prostate cancer who relapsed after initial MAB, including surgical or medical castration combined with antiandrogens, from January 1998 to December 2009. When the serum prostate-specific antigen (PSA) level was increased on three consecutive occasions, we discontinued the antiandrogen and then administered an alternative antiandrogen. Seven patients were assessed for antiandrogen withdrawal syndrome (AWS). The effect of the second-line MAB was evaluated by the serum PSA level, and response was subdivided into > or =50% and or =50% PSA reductions with a mean response duration of 13.4+/-5.4 months. Nine (19.2%) patients reached or =50% PSA reduction group, <50% PSA reduction group, and PSA elevation group was 15.6+/-12.9 months, 11.8+/-6.0 months, and 8+/-6.5 months, respectively. That is to say, it was significantly longer in the responder groups (p=0.038). CONCLUSIONS: Second-line MAB using an alternative antiandrogen is an effective treatment option before cytotoxic chemotherapy in patients who relapse after initial MAB.

Extensive Systemic Sarcoidosis with Testicular Involvement Mimicking Metastatic Testicular Cancer

Sarcoidosis is an idiopathic, multisystem disease that rarely involves the genitourinary tract. Here we present an unusual case of testicular sarcoidosis with extensive lymphadenopathy that mimicked a metastatic testicular tumor. A 27-year-old male presented with a palpable right testicular mass accompanied by multiple palpable inguinal lymph nodes. The scrotal ultrasound showed a hypoechoic lesion at the inferior portion of the right testis. Extensive enlarged lymph nodes were noted in multiple areas on the abdominal computed tomography. Preoperative testicular tumor markers were within the normal range. Exploration of the right testis with a frozen section analysis of the right testicular mass and of a palpable right inguinal lymph node showed granulomatous inflammation. The testis was salvaged and the final pathological diagnosis was sarcoidosis. Treatment with high-dose corticosteroids resulted in complete resolution of the intratesticular mass and a significant decrease in the extent of the lymphadenopathy.

Pathologic Results of Radical Prostatectomies in Patients with Simultaneous Atypical Small Acinar Proliferation and Prostate Cancer

PURPOSE: The incidence of adenocarcinoma on a subsequent biopsy following a diagnosis of atypical small acinar proliferation (ASAP) ranges from 34% to 60%. We reexamined radical prostatectomy (RP) specimens of patients diagnosed as having synchronous ASAP with prostate cancer (PCa) to evaluate pathological entities and the clinical significance of ASAP. MATERIALS AND METHODS: From January 2007 to December 2008, a total of 118 patients who had been diagnosed with adenocarcinoma on prostate needle biopsy underwent RP. Forty-six of the 118 patients (39%) were diagnosed as having synchronous ASAP with PCa on the prostate needle biopsy. Using whole-mount sections and prostate mapping, we evaluated the RP specimens that were close sections to the ASAP on prostate needle biopsy. All tissues were examined by immunohistochemistry with high molecular weight cytokeratin (34betaE12), p63, and AMACR/P504S added to initial H&E stains by one pathologist. RESULTS: Thirty-six of the 46 patients (78%) were diagnosed as having adenocarcinoma at sites of ASAP on the initial prostate needle biopsies. The Gleason score was 5 to 6 in 22 patients (61%), 7 in 3 (8%), and unknown due to multifocal and microfocal lesions in 11 (31%). The tumor volume of 14 of the 36 patients (39%) was 0.5 cc or less and was unknown due to multifocal and microfocal lesions in 8 (22%). CONCLUSIONS: Most ASAP on initial prostate needle biopsy was a true pathological entity, in other words, prostatic adenocarcinoma. Aggressive approaches including more extended repeat biopsy with additional biopsy of the site of the ASAP are needed to diagnose PCa in patients with ASAP.

Predictive Factors of Prostate Cancer at Repeat Biopsy in Patients with an Initial Diagnosis of Atypical Small Acinar Proliferation of the Prostate

PURPOSE: The factors that predict prostate cancer detection on repeat biopsy were evaluated in patients with atypical small acinar proliferation (ASAP) on the initial biopsy. MATERIALS AND METHODS: From 2003 to 2008, 3,130 men with suspected prostate cancer underwent a prostate needle biopsy, and 244 (7.8%) were diagnosed as having ASAP. One hundred seventy of 244 patients were rebiopsied at least once more. They were classified into a prostate cancer group and a noncancer group according to the final pathological diagnosis. The database of rebiopsied patients included age, initial prostate-specific antigen (PSA), PSA density (PSAD), PSA velocity (PSAV), total prostate volume (TPV), and transitional zone volume of the prostate (TZV). We compared differences in the aforementioned parameters between the 2 groups. RESULTS: A total of 57 patients (33.5%) with ASAP were ultimately shown to have prostate cancer. Univariate analysis showed that PSAD (p=0.002), PSAV (p=0.001), TPV (p=0.035), and TZV (p=0.005) differed significantly between the cancer and noncancer groups. The results of the multivariate analysis showed that PSAD (p=0.022), PSAV (p<0.001), and TPV (p=0.037) had a statistically significant correlation with cancer detection. CONCLUSIONS: PSAD, PSAV, and TPV are predictive factors of prostate cancer in patients with an initial diagnosis of ASAP of the prostate. Although repeat biopsy is mandatory irrespective of PSA values, the follow-up of PSA may help to estimate the probability of cancer in these men.

Prostate Cancer Detection Rate of Rebiopsy in Patients with an Initial Diagnosis of Atypical Small Acinar Proliferation of the Prostate

PURPOSE: Atypical small acinar proliferation (ASAP) denotes the presence of suspicious glands with insufficient cytological architecture for a definitive prostate cancer diagnosis. We evaluated the subsequent prostate cancer detection rate of rebiopsy in patients with an initial diagnosis of ASAP. MATERIALS AND METHODS: Between January 2003 and December 2006, 1,416 men with suspected prostate cancer underwent a transrectal ultrasound-guided prostate biopsy, and 214 (15.1%) were diagnosed as having ASAP. Ninety-five of the 215 patients underwent at least one more biopsy. We evaluated the cancer detection rates after rebiopsy. RESULTS: In men with ASAP, 36 patients (37.9%) had prostate cancer. The cancer detection rates of the 1st, 2nd, and 3rd rebiopsies were 30.5%, 23.8%, and 40%, respectively. Mean patient age and prostate-specific antigen did not differ significantly between the prostate cancer and noncancer groups after rebiopsy. Prostate volume, however, was significantly smaller in the cancer group (p<0.05). CONCLUSIONS: Our results showed a detection rate for prostate cancer of 37.9% after an initial diagnosis of ASAP, which indicates that an initial diagnosis of ASAP mandates rebiopsy.

Basal Cell Carcinoma of the Prostate

Basal cell carcinoma (BCC) of the prostate, a rare variant of prostate cancer, is derived from the basal cells of prostatic ducts and acini. BCC generally occurs in elderly men with obstructive voiding symptoms and levels of serum prostate-specific antigen within the normal range. In most cases, diagnosis is made through transurethral resection or simple enucleation. Most cases are indolent, but local recurrence and metastasis have been reported in a few cases. Thus, radical surgery and long-term follow-up are recommended. We report a case of a 54-year-old man who underwent radical retropubic prostatectomy after being diagnosed with BCC during a transurethral resection performed for lower urinary tract symptoms. The patient has remained free of disease for 4 months after surgery.

Spontaneous Perinephric Urinoma in a Patient with Neurogenic Bladder

Spontaneous rupture of the renal pelvis or ureteropelvic juction area with extravasation of urine into the perinephric space is an uncommon pathologic condition (1). We report a case of 72-year-old woman who suffered 2 days of left loin pain. The patient has got residual urine sensation and weak urine stream since she has gone through a radical hysterectomy 17 years before. Because of these symptoms of voiding difficulty, the patient had abdominal straining during her urination. A CT scan exhibited renal pelvis rupture with perirenal extravasation of urine due to severe hydronephrosis, that was exacerbated by hidden neurogenic bladder disease. Moreover, the patient has detrusor underactivity and high intravesical pressure at voiding trial in the urodynamic study. One month after the percutaneous nephrostomy insertion into the left renal pelvis, the patient was successfully treated. The size of renal pelvis decreased. Moreover, urinoma disappeared in follow up CT scan image.

Complete Remission of Renal Cell Carcinoma with Metastases to Lung and Bone Following Initial Interferon-alpha Immunotherapy and Adjuvant Nephrectomy / 대한비뇨기과학회지

Patients with metastatic renal cell carcinomas have a median survival of less than 1 year and a 0-20% 5-year survial. The immunotherapy agent interferon-alpha has consistently produced objective responses rarely exceeding 20% of treated patients. Moreover, in patients with metastases to brain, liver or bone, the prognosis is extremely poor. A 66-year-old man, with a right renal cell carcinoma, with metastases to lung and bone who had entered a remarkable complete radiological remission of the metastases to lung and bone by 82 months following interferon-alpha immunotherapy, underwent a nephrectomy. The patient has remained recurrence free for 16 months after the nephrectomy.

The Long-Term Outcomes of Augmentation Cystoplasty in Spinal Cord Injury Patients / 대한비뇨기과학회지

PURPOSE: The long-term outcomes of augmentation cystoplasty were investigated in spinal cord injury (SCI) patients with a neurogenic bladder, and included a study of the complications and patients' satisfaction. MATERIALS AND METHODS: 19 SCI patients that underwent an augmentation cystoplasty, between 1988 and 1994, were retrospectively reviewed. The mean follow-up period was 120, ranging from 94 to 169 months. The changes in the intravesical pressure, bladder capacity and complications were investigated. Urological examinations, including history taking, medical records, radiological evaluations and urodynamic studies were undertaken. All the patients were interviewed by direct contact. RESULTS: Six months postoperatively, the urodynamic results showed significantly decreased intravesical pressures and increased bladder capacities. The intravesical pressure (cmH2O) was decreased from 89.0+/-16.49 to 28.0+/-5.69 (p<0.05), and the functional bladder capacity (ml) was increased from 125.0+/-53.30 to 480.0+/-43.33 (p<0.05). From the long-term follow-up, 10 years postoperatively, the results were similar to the previous data (21.0+/-3.88cmH2O and 510.0+/-60.27ml). The symptomatic urinary tract infections had disappeared, but the asymptomatic bacteriuria continued. The vesicoureteral reflux was eliminated, and the renal function normalized, in all patients. The hydronephrosis had disappeared in most patients (89%). A few postoperative complications were reported. Most patients were very satisfied symptomatically (89%), with no patient expressing dissatisfaction. A clean intermittent catheterization (CIC) was performed every 4 to 6 hours, with the mean volume of drained urine was 450, ranging from 400 to 600ml. CONCLUSIONS: Augmentation cystoplasty could be an excellent method of treatment in selected patients with SCI. There were no significant complications, and a high degree patients' satisfaction, on the long-term follow-up.

Primary Squamous Cell Carcinoma of the Ureter after Reterocutaneoustomy / 대한비뇨기과학회지

Primary squamous cell carcinomas of the renal pelvis and ureter are rare tumors, accounting for less than 1% of all primary tumors of the upper urinary tract. The ratio of renal pelvis to ureter tumors is approximately 6:1. The pathogenesis is assumed to begin with an urothelial metaplasia, as a result of a reaction to chronic irritation and infection, which lead to dysplasia, and ultimately to a squamous cell carcinoma. Only one case of a squamous cell carcinoma of the ureter has been reported in the Korean literature. We report a case of a primary squamous cell carcinoma of the ureter, as a result of a reaction to chronic irritation and infection in a 48-year-old male patient.
