Lymphoma of the prostate is exceedingly rare. Much more common than primary lymphoma of the prostate id secondary involvement of malignant lymphomas originating at other sites. A variety of treatments have bee n used, including prostatectomy, radiotherapy or combinations of chemotherapy and radiotherapy. Generally, the prognosis is very poor, and there is currently no consensus regarding treatment. We report on a patient with T-cell lymphoma who presented with symptoms of bladder neck obstruction. The patient has been asymptomatic and under complete remission after completion of doxorubicin-based chemotherapy for 2 cycles.

2.Quality of Life in Prostate Cancer Patient Undergoing Androgen Deprivation Therapy.
Korean Journal of Urological Oncology 2016;14(1):10-17
Androgen deprivation therapy (ADT) has been one of the standard protocol for treating prostate cancer. The role for hormonal treatment initially was restricted to men with metastatic and inoperable, locally advanced disease. Now it has been extended to neoadjuvant or adjuvant therapy for surgery and radiotherapy, for biochemical relapse after surgery or radiation, and even as primary therapy for non-metastatic disease. Although ADT can improve survival, it can also cause significant morbidity and a decrement in quality of life (QOL). In this article, we discuss QOL problem caused by ADT and suggest for mitigating harm of ADT.

Adenosquamous cell carcinoma (Ad-SCC) of the colon is rare. The pathogenesis of Ad-SCC is unclear, however, several hypotheses have been suggested. The clinical presentation and gross findings of Ad-SCC of the colon are similar to those of adenocarcinoma of the colon, but Ad-SCC has a more aggressive clinical course and a poorer prognosis. We report on two cases of Ad-SCC of the colon with obstruction; a collision-type Ad-SCC that has not only obstruction but also numerous hepatic metastases, and a composite-type Ad-SCC treated with left hemicolectomy followed by an adjuvant chemotherapy.

Intrathecal morphine can provide goad analgesia for the first stage of labor. However, a long latency, high incidence of side effects, and lack of perineal anesthesia limit its usefulness. We wished to make a short the latency and reduce the dose of morphine, administered morphine 0.2 mg, 0.3 mg, combined with fentanyl 25 micrograms intrathecally. Forty-five laboring patients were studied and randomly divided into two groups' group I (n=24) received intrathecal morphine 0.2 mg with fentanyl 25 ug; group II (n=21) received intrathecal morphine 0.3 mg with fentanyl 25 ug; We compared the analgesia and side effects of group I to those of group II. Analgesia was assessed using the 100 mm visual linear analog(VLA) as the time elapsed from the drug administration to the delivery. The onset of analgesia was rapid(within 5 minutes) in both groups and VLA scores did not differ at any observation point between the groups. The effect of analgesia was lasted until the perineum was distended by the fetus. The incidence of nausea or vomiting was 41.7%(10/24) in group I, and 33.3%(7/21) in group II. Pruritus occured 87.5%(21/24)) in group I and 90.5%(19/21) in group II. The majority of pruritus occured soon after administration of study drug. There were more instances of urinary retention in group II (61.9%) than in group I(37.5%). No patient developed postdural puncture headache, vital sign alteration or respiratory depression. Most of all the patients in this study said that they were satisfied with this analgesic technique and would like to receive intrathecal narcotic analgesia for future labor. With the above results we conclude that intrathecal morphine 0.2 mg with fentanyl 25 ug for labor pain provides rapid and effective analgesia as 0.3 mg intrathecal morphine with fentanyl 25 ug.

PURPOSE: Enterocystoplasty is the method commonly used in clinical practice. The use of intestinal segments in the urinary tract for the reconstructive purposes has been reported numerous complications: urinary tract infection, stone formation, hyperchloremic acidosis, hypokalemia, urinary obstruction secondary to mucus plugs, and malignancy developing. We studied on the feasibility of creating an enterocystoplasty with a reversed seromuscular ileal segment to decrease the likelihood of recognized complications in cases of standard bowel replacement. MATERIALS AND METHODS: Augmentation enterocystoplasty was performed in 21 male, 400-450gm, Sprague-Dawley rats with a patch of ileum. There were 3 groups, including 1 group of 9 rats that underwent augmentation conventionally, while another group of 8 rats were augmented using reversed seromuscular flaps and the other rat was died for postoperative ileus. The other group of 3 rats were sham operated. The animals survived without significant complications and were sacrificed at 4 or 12 weeks. RESULTS: The bladder capacities in both group were no significant differences. The size of the intestinal patchs were markedly decreased in reversed seromuscular flaps. The urine white blood cells and mucus production were much higher in the conventional type, but intraperitoneal mucus production and postoperative adhesion were seen mostly in reversed seromuscular types. CONCLUSIONS: Reversed seromuscular flaps showed little mucus production in urine and urinary infection compared to those animals with flaps undergone conventional method. Unfortunately, intraperitoneal mucus production and graft contracture were much higher in those procedures. Further studies would be needed for clinical availability of reversed flap.

PURPOSE: We reviewed the incidence, causes, location, treatment and prognosis of the severe iatrogenic ureteral avulsions caused by ureteroscopy procedures. MATERIALS AND METHODS: We analyzed the records of eight patients with ureteral avulsion out of 683 patients treated with ureteroscopic procedures, retrospectively. The patients had surgical correction or ureteral double-J stenting for the iatrogenic ureteral avulsions. RESULTS: The incidence of ureteral avulsion was 1.17%. While seven cases occurred during ureteroscopic removal of a stone, five cases among them occurred during stone basketing and two cases occurred during insertion of the ureteroscope. Another case among eight avulsion cases occurred while removing the during an endopyelotomy for a ureteral stricture. Depending on the length of the ureteral avulsion, four cases were over 2cm, the patientsopen surgical repair for ureteral continuity restoration immediately; three cases, under 2cm, were treated with indwelling ureteral double J stents, and one case with an injury to the entire ureter was treated with a nephrectomy. The result of the surgical treatment as the initial treatment was good in all cases. On the other hand, among the three cases with an inserted ureteral double-J stent, one case had aresult and the other two developed hydronephrosis. CONCLUSION: Careful attention to surgical techniques and awareness of risk factors and types of potential injuries are essential to reduce severe iatrogenic ureteral avulsions. Our reports suggest that open surgical repair is better than an indwelling ureteral double-J stent for patients with a ureteral avulsion.

10.Next-Generation Sequencing in Prostate Cancer
Seong Hyeon YU ; Taek Won KANG
Korean Journal of Urological Oncology 2020;18(1):18-23
Prostate cancer is one of the most common cancer worldwide, androgen-deprivation therapy (ADT) has been the mainstream of treatment after treatment failure of localized cancer. However, despite the rapid initial response of ADT, most patients eventually progress to metastatic castration-resistant prostate cancer (mCRPC). Treatment decisions for patients with mCRPC are a very complex process, and its response is varied and difficult to predict due to individual differences. Therefore, novel biomarkers and therapeutic targets based on better understanding of molecular landscape of prostate cancer are needed. In this review, we summarized the genomic information, informative biomarkers and potential molecular targets using next-generation sequencing technology of prostate cancer.
