Treatment options for clinically localized prostate cancer include surgical extirpation, radiation therapy(external beam radiation therapy and/or brachytherapy), or watchful waiting. Cryosurgery has recently re-emerged as a developing technology and as a minimally invasive treatment option. There may be technical difficulties in placing cryoprobes in patient with a penile prosthesis. To the best of our knowledge, this is the first report of cryosurgical ablation of the prostate in a prostate cancer patient with a penile prosthesis.

PURPOSE: The aim of this study was to evaluate the outcome of ureter stones with expectant management and the clinical factors associated with stone passage in Koreans. MATERIALS AND METHODS: We reviewed the charts of patients who visited the emergency room or urological office of our institution with acute renal colic between 2001 and 2008. A total of 656 ureter stone formers were enrolled in this study who had decided to be treated by expectant management. Clinical data such as gender, age, size and location of the stone, body mass index, and previous stone history were analyzed to find the factors related to spontaneous passage of ureter stones. RESULTS: Of the 656 ureter stones, 566 stones (86.3%) were spontaneously expelled. Mean duration of follow-up was 17.5 days (range, 1 to 100 days). Mean time to stone passage was 6.8 days for stones less than 2 mm in size, 12.6 days for stones 2 to 4 mm, 14.8 days for stones 4 to 6 mm, and 21.8 days for stones 6 to 8 mm (p<0.001). The cumulative spontaneous passage rate was 55.3% in 7 days, 73.7% in 14 days, 88.5% in 28 days, and 97.7% in 60 days after the first attack. A total of 90 patients (13.7%) required interventions because of symptom relapse or renal deterioration that was related to the location and size of the stone (each, p<0.001). The more proximal the location and the larger the stone was than 6 mm, the less the chance of spontaneous passage (each, p<0.001). CONCLUSIONS: Size and location of ureter stones are the most important factors for predicting the spontaneous passage of the stone. If a patient has a distal ureter stone of less than 6 mm in size, it is acceptable for the urologist to observe for spontaneous passage for 2 months.

PURPOSE: To compare the safety and efficacy of naftopidil and tamsulosin with prednisolone as medical expulsive therapy for distal ureteric stones. MATERIALS AND METHODS: Between July 2010 and March 2012, 120 adult patients presenting with distal ureteric stones of size 5 to 10 mm were randomized equally to tamsulosin (group A), naftopidil (group B) or watchful waiting (group C). Tamsulosin or naftopidil was given for a maximum of four weeks. In addition patients in group A and B were given 5 mg prednisolone once daily (maximum one week). Stone expulsion rate, time to stone expulsion, analgesic use, number of hospital visits for pain, follow-up and endoscopic treatment and adverse effects of drugs were noted. Statistical analyses were done using chi-square test, Mann-Whitney test and analysis of variance. RESULTS: There was a statistically higher expulsion rate in groups A (70%) and B (87.5%) as compared to group C (32.5%) (p<0.001). The expulsion rates were not statistically different between groups A and B (p=0.056). The mean time to expulsion was comparable between groups A and B but longer in group C. Analgesic use was significantly lower in groups A and B. Average number of hospital visits for pain, follow-up and endoscopic treatment was similar in all groups. There was no serious adverse event. CONCLUSIONS: Medical expulsive therapy for the distal ureteric stones using either naftopidil or tamsulosin in combination with prednisolone is safe and efficacious.

4.Small Renal Masses: Surgery or Surveillance.

The incidence of kidney cancer has been rising over the past two decades, especially in cases in which the disease is localized and small in size (<4 cm). This rise is mainly due to the widespread use of routine abdominal imaging such as ultrasonography, computed tomography, and magnetic resonance imaging. Early detection was initially heralded as an opportunity to cure an otherwise lethal disease. However, despite increasing rates of renal surgery in parallel to this trend, mortality rates from renal cell carcinoma have remained relatively unchanged. Moreover, data suggest that a substantial proportion of small renal masses are benign. As a result, the management of small renal masses has continued to evolve along two basic themes: it has become less radical and less invasive. These shifts are in part a reflection of an improved understanding that the biology of incidentally discovered renal cell carcinoma may be more indolent than previously thought. However, not all small renal masses are indolent, and de novo metastatic disease can develop at the initial presentation. Therefore, it is with this background of clinical uncertainty and biological heterogeneity that clinicians must interpret the benefits and disadvantages of various clinical approaches to small renal masses.

To reduce treatment-related side effects in low-risk prostate cancer (PCa), both focal therapy and deferred treatments, including active surveillance (AS) and watchful waiting (WW), are worth considering over radical prostatectomy (RP). Therefore, this study aimed to compare long-term survival outcomes between focal therapy and AS/WW. Data were obtained and analyzed from the Surveillance, Epidemiology, and End Results (SEER) database. Patients with low-risk PCa who received focal therapy or AS/WW from 2010 to 2016 were included. Focal therapy included cryotherapy and laser ablation. Multivariate Cox proportional hazards models were used to compare overall mortality (OM) and cancer-specific mortality (CSM) between AS/WW and focal therapy, and propensity score matching (PSM) was performed to reduce the influence of bias and unmeasured confounders. A total of 19 292 patients with low-risk PCa were included in this study. In multivariate Cox proportional hazards model analysis, the risk of OM was higher in patients receiving focal therapy than those receiving AS/WW (hazard ratio [HR] = 1.35, 95% confidence interval [CI]: 1.02-1.79, P = 0.037), whereas no significant difference was found in CSM (HR = 0.98, 95% CI: 0.23-4.11, P = 0.977). After PSM, the OM and CSM of focal therapy and AS/WW showed no significant differences (HR = 1.26, 95% CI: 0.92-1.74, P = 0.149; and HR = 1.26, 95% CI: 0.24-6.51, P = 0.782, respectively). For patients with low-risk PCa, focal therapy was no match for AS/WW in decreasing OM, suggesting that AS/WW could bring more overall survival benefits.

Prostate cancer (PCa) is the second-most common cancer among men. Both active surveillance or watchful waiting (AS/WW) and focal laser ablation (FLA) can avoid the complications caused by radical treatment. How to make the choice between these options in clinical practice needs further study. Therefore, this study aims to compare and analyze their effects based on overall survival (OS) and cancer-specific survival (CSS) to obtain better long-term benefits. We included patients with low-risk PCa from the Surveillance Epidemiology and End Results database of 2010-2016. Multivariate Cox proportional hazard analyses were conducted for OS and CSS in the two groups. To eliminate bias, this study applied a series of sensitivity analyses. Moreover, Kaplan-Meier curves were plotted to obtain survival status. A total of 18 841 patients with low-risk PCa were included, with a median of 36-month follow-up. According to the multivariate Cox proportional hazard regression, the FLA group presented inferior survival benefits in OS than the AS/WW group (hazard ratio [HR]: 2.13, 95% confidence interval [CI]: 1.37-3.33, P < 0.05). After adjusting for confounders, the result persisted (HR: 1.69, 95% CI: 1.02-2.81, P < 0.05). According to the results of the sensitivity analysis, the inverse probability of the treatment weighing model indicated the same result in OS. In conclusion, AS/WW and FLA have the advantage of fewer side effects and the benefit of avoiding overtreatment compared with standard treatment. Our study suggested that AS/WW provides more survival benefits for patients with low-risk PCa. More relevant researches and data will be needed for further clarity.

7.Pros and cons of perioperative therapy in the protection of organ function in rectal cancer.

The goal of rectal cancer treatment should be to better protect organ function and improve patients' quality of life on the basis of ensuring radical resection. The current evidence has proved the superiority of perioperative chemoradiotherapy in reducing local recurrence and improving long-term survival. From the perspective of organ function protection, however, perioperative chemoradiotherapy has both disadvantages and advantages. Despite the great help in improving long-term outcomes, adverse reactions of chemoradiotherapy can aggravate defecation, urination and sexual dysfunction. Also, for patients with significant or complete remission, if the treatment strategy of local resection or close follow-up is selected, organ function can be preserved to the greatest extent. The key to the choice of treatment is to evaluate preoperatively whether pathological complete response is achieved. It should be kept in mind that preserving organ itself is not the same as protecting organ function. For patients who need perioperative chemoradiation, the optimal treatment methods should be chosen based on the patient's condition. Surgeons should fully evaluate organ function before operation, select the appropriate treatment strategy, pay special attention to the protection of important organs and nerves during surgeries, and carry out close postoperative follow-up and organ function rehabilitation as soon as possible, so as to reduce the incidence of dysfunction and the impact on the quality of life.

8.Evaluation strategy of complete response after neoadjuvant therapy for rectal cancer.
Chinese Journal of Surgery 2023;61(9):738-743
Currently, the standard of clinical complete response (cCR) after neoadjuvant chemoradiotherapy (nCRT) for local advanced rectal cancer generally lacks pathological examination, the cCR judged by the current standard is still far from the real pathological complete response. After nCRT, due to the presence of tissue edema and fibrosis, MRI is highly uncertain in determining the staging of local lesions. The precision of colonoscopy biopsy is generally low because residual cancer foci exist primarily in the muscular layer, which limits the determination of cCR by colonoscopy biopsy. Local excision through the anus can resect the whole intestinal wall tissue, which is relatively accurate and close to the real state of remission of the lesion, but there are many problems, such as affecting anal function, high rate of complications, and increased difficulty of following radical surgery. Based on the present diagnosis of cCR, the authors put forward the concept of modified cCR (m-cCR) which combined with the pathological standard of transanal multipoint full-layer puncture biopsy. It is possible to improve the accuracy of cCR, and improve the safety of cCR patients who receive wait-and-watch therapy without increasing complications or affecting anal function. The exact conclusion needs to be confirmed by further studies.

PURPOSE: Ureteral calculi are commonly encountered in the emergency department. Ureteral calculi influence the quality of life of patients, causing pain and economic burden. The optimal management of ureteral calculi remains a challenge for practicing physicians; therefore, this study was designed to determine which factors are related to the failure of their spontaneous passage. METHODS: This study was a retrospective review of the medical records of one hundred ninety-five patients who visited the emergency department complaining of renal colic from February 2012 to December 2012. Bivariate analyses were conducted relating physical, laboratory, and radiological methods to predict the failure of spontaneous passage. A multivariate logistic regression model was then derived, with all variables in the final model significant at p<0.05. RESULTS: One hundred twenty-eight stones were spontaneously expelled and sixty-seven were not. The mean stone size was significantly larger in the non-passage group than the passage group (p<0.001). When the stones were located in the upper ureter, or on the right side, the spontaneous passage rate was lower (p<0.001, p=0.035). Increased neutrophils and positive tests for urinary protein and bilirubin were also associated with the decreased likelihood of spontaneous passage (p=0.046, p=0.029, and p=0.048, respectively). In addition, the longer duration of symptoms and a previous history of ureteral calculi were related to a lower chance of spontaneous passage (p=0.005, p=0.019). CONCLUSION: Prognostic factors of failure, after the initial expectant management of ureteral calculi, included: calculi size, location (e.g., side), the duration of symptoms, the previous history, neutrophil levels, urinary bilirubin levels, and urinary protein levels. Therefore, emergency physicians need to cautiously decide between watchful waiting and interventions in these patients.

10.Review the Treatment Outcome in the Adenocarcinoma of the Prostate.
Journal of the Korean Medical Association 2004;47(5):432-440
The management of prostate cancer which is common in the elderly is problematic and remains controversial. Patient selection may have a crucial role in predicting outcome, because of death from other causes may occur before death from prostate cancer in many cases_ The best approach may be to have patients choose a therapy after being well informed of the outcome including the relative risks and benefits from each treatment option. Assessment of treatment outcome has become more sensitive and rapid after serum prostate specific antigen (PSA) is available in routine followup.PSA has identified substantially more failure following all radical therapies than was previously detected, which is reporting long-term outcome with cure rates well below 40% not only for surgery but also radiation. Though watchful waiting or conservative management is frequently criticized as a poor option, it maybe a valid option for all men regardless of age or health status. However, radical prostatectomy still offers the best opportunity to cure the disease Because of uncertainty of therapeutic benefit and variation in practice patterns etc, practice guideline development is needed.
