RATIONALE
Retroperitoneal hematomas are relatively common in patients undergoing nephrectomy. Herein, we report an unusual case involving a giant retroperitoneal hematoma and subsequent duodenal ulcerative bleeding following a radical nephrectomy.
PATIENT CONCERNS
A 77-year-old woman was admitted to our hospital for lower back pain, and she had severe right hydronephrosis and a urinary tract infection.
DIAGNOSES
The patient was diagnosed and confirmed as high-grade urothelial carcinoma.
INTERVENTIONS
After ineffective conservative treatments, a right radical nephrectomy and ureteral stump resection were performed. The patient received proton pump inhibitors to prevent stress ulcer formation and bleeding. On the first day post-surgery, she had normal gastrointestinal (GI) endoscopy findings. On the second day post-surgery, abdominal computed tomography revealed a retroperitoneal hematoma. Notably, 14 days post-surgery, massive GI bleeding occurred, and GI endoscopy identified an almost perforated ulcer in the bulbar and descending duodenum.
OUTCOMES
The patient died on day 15 after surgery.
LESSONS
Duodenal ulceration and bleeding might occur following a retroperitoneal hematoma in patients treated with nephrectomy. Timely intervention may prevent duodenal ulcers and complications, and thus could be a promising life-saving intercession.

Review
BACKGROUND
Genitourinary malignancies have a substantial impact on men and women in the USA as they include three of the ten most common cancers (prostate, renal, and bladder). Other urinary tract cancers are less common (testis and penile) but still have profound treatment implications related to potential deficits in sexual, urinary, and reproductive function. Evidenced-based practice remains the cornerstone of treatment for urologic malignancies.
METHODS
The authors reviewed the literature in consideration of the four top articles influencing clinical practice in the prior calendar year, 2022.
RESULTS
The PROTECT trial demonstrates favorable 15-years outcomes for active monitoring of localized prostate cancer. The SEMS trial establishes retroperitoneal lymph node dissection as a viable option for patients with seminoma of the testis with limited retroperitoneal lymph node metastases. CheckMate 274 supports adjuvant immunotherapy following radical cystectomy for muscle-invasive bladder cancer with a high risk of recurrence. Data reported from the IROCK consortium reinforce stereotactic ablative radiotherapy as an option for localized renal cell carcinoma.
CONCLUSION
The care for patients with urologic cancers has been greatly improved through advances in surgical, medical, and radiation oncologic treatments realized through prospective randomized clinical trials and large multicenter collaborative groups.

INTRODUCTION
Pancreatic serous cystic neoplasm (SCN) is usually benign and is often managed using imaging surveillance if asymptomatic. It has a higher incidence in females but is rare in younger age groups. Acute hemorrhagic complications associated with SCN are infrequent. Whether asymptomatic SCN can cause acute hemorrhage, especially in women of childbearing age, is not well-established.
PRESENTATION OF CASE
A 30-year-old Japanese female, who was six months postpartum and under surveillance for asymptomatic pancreatic SCN, presented to the emergency department with gradually worsening left lateral abdominal pain. Regular ultrasound revealed no change in SCN size; however, no imaging surveillance had been conducted over the past two years. She had pain in the entire abdomen, which intensified around the navel and elicited guarding. Abdominal contrast-enhanced computed tomography revealed a cystic mass in the pancreatic tail with a contrast blush within the cyst and an adjacent retroperitoneal hematoma. Endovascular embolization was performed to control the hemorrhage. The patient had an uneventful medical recovery and was discharged five days after embolization. Five months after discharge, she underwent laparoscopic distal pancreatectomy and splenectomy as an elective surgery and was discharged uneventfully.
DISCUSSION
Even with periodic imaging surveillance, pancreatic SCN can suddenly cause spontaneous hemorrhage. Clinicians should be aware that pancreatic SCN can potentially cause life-threatening complications, including spontaneous hemorrhage.
CONCLUSION
We report a case of an unexpected complication with spontaneous hemorrhage in a young woman who was under imaging surveillance for pancreatic SCN. The patient was successfully treated with angioembolization and planned laparoscopic surgery.

Review
INTRODUCTION
Retroperitoneoscopic adrenalectomy (RPA) has gained increasing popularity with its excellent perioperative outcomes and direct surgical access compared to other adrenalectomy approaches. We review perioperative outcomes of RPA by a specialized endocrine surgeon before and after expert intensive trainings (EITs), and to that of other laparoscopic adrenalectomy approaches at our center over a 9-year period, aiming to ascertain if RPA is worth the steep learning curve.
MATERIAL AND METHODS
One hundred twenty one adrenalectomies were performed between January 2014 to June 2022. Patient demographic, tumor characteristics, and perioperative outcomes were retrospectively reviewed. The primary endpoints included procedure duration, complications, and length of stay. Part I of the study examined the effect of EITs on RPA's learning curve, and part II compared these outcomes with that of the alternative approach, transabdominal lateral adrenalectomy (TLA).
RESULTS
Both procedure duration and days in hospital markedly decreased after the two EITs for RPA. RPA resulted in a shorter procedure duration and hospital stay compared to TLA, and had lesser and milder intraoperative and postoperative complications compared to TLA.
CONCLUSIONS
RPA results in safe and excellent outcomes, and offers additional benefit of direct surgical access, feasibility in patients with previous abdominal surgery, high body mass index, and multiple comorbidities. The steep learning curve can be overcome and shortened by EITs, motivating centers with specialized endocrine surgery to integrate RPA training into its curriculum, given its foreseeable rewarding outcomes.

INTRODUCTION
Abdominal obesity increases the risk of developing ovarian cancer but the molecular mechanisms of how obesity supports ovarian cancer development remain unknown. Here we investigated the impact of obesity on the immune cell and gene expression profiles of distinct abdominal tissues, focusing on the peritoneal serous fluid (PSF) and the omental fat band (OFB) as critical determinants for the dissemination of ovarian metastases and early metastatic events within the peritoneal cavity.
METHODS
Female C57BL/6 mice were fed a low-fat (LFD) or a high-fat diet (HFD) for 12 weeks until the body weights in the HFD group were significantly higher and the mice displayed an impaired glucose tolerance. Then the mice were injected with the murine ovarian cancer cells (MOSE-LTICv) while remaining on their diets. After 21 days, the mice were sacrificed, tumor burden was evaluated and tissues were harvested. The immune cell composition of abdominal tissues and changes in gene expression in the PSF and OFB were evaluated by flow cytometry and qPCR RT2-profiler PCR arrays and confirmed by qRT-PCR, respectively. Other peritoneal adipose tissues including parametrial and retroperitoneal white adipose tissues as well as blood were also investigated.
RESULTS
While limited effects were observed in the other peritoneal adipose tissues, feeding mice the HFD led to distinct changes in the immune cell composition in the PSF and the OFB: a depletion of B cells but an increase in myeloid-derived suppressor cells (MDSC) and mono/granulocytes, generating pro-inflammatory environments with increased expression of cyto- and chemokines, and genes supporting adhesion, survival, and growth, as well as suppression of apoptosis. This was associated with a higher peritoneal tumor burden compared to mice fed a LFD. Changes in cellular and genetic profiles were often exacerbated by the HFD. There was a large overlap in genes that were modulated by both the HFD and the cancer cells, suggesting that this 'genetic fingerprint' is important for ovarian metastases to the OFB.
DISCUSSION
In accordance with the 'seed and soil' theory, our studies show that obesity contributes to the generation of a pro-inflammatory peritoneal environment that supports the survival of disseminating ovarian cancer cells in the PSF and the OFB and enhances the early metastatic adhesion events in the OFB through an increase in extracellular matrix proteins and modulators such as fibronectin 1 and collagen I expression as well as in genes supporting growth and invasion such as Tenacin C. The identified genes could potentially be used as targets for prevention strategies to lower the ovarian cancer risk in women with obesity.

BACKGROUND
Tumor immunotherapy is a new treatment breakthrough for retroperitoneal liposarcoma (RPLS), which is highly invasive and has few effective treatment options other than tumor resection. However, the heterogeneity of the tumor immune microenvironment (TIME) leads to missed clinical diagnosis and inappropriate treatment. Therefore, it is crucial to evaluate whether the TIME of a certain part of the tumor reliably represents the whole tumor, particularly for very large tumors, such as RPLS.
METHODS
We conducted a prospective study to evaluate the TIME in different regions of dedifferentiated RPLS (DDRPLS) by detecting the expressions of markers such as CD4, CD8, Foxp3, CD20, CD68, LAMP3, PD-1 tumor-infiltrating lymphocytes (TILs), and PD-L1 in tumors and corresponding paratumor tissues via immunohistochemistry and RNA sequencing.
RESULTS
In DDRPLS, very few TILs were observed. Differentially expressed genes were significantly enriched in cell part and cell functions, as well as the metabolic pathway and PI3K-Akt signaling pathway. In addition, for most tumors (70-80%), the TIME was similar in different tumor regions.
CONCLUSIONS
For most tumors (70-80%), the TIME in any region of the tumor reliably represents the whole tumor. DDRPLS may regulate cell functions by modulating the metabolic and PI3K-Akt signaling pathways to promote its malignant behavior.

Somatic-type malignancy (STM) can occur infrequently within a primary or metastatic testicular germ cell tumor (TGCT) and is associated with dismal prognosis and survival. STM with chondrosarcomatous features is exceedingly rare and head and neck involvement has not been previously documented. A 39-year-old white man presented with nasal obstruction and epistaxis. Imaging disclosed a 6.9-cm expansile tumor involving the nasal cavity and skull base with intraorbital and intracranial extension. The histopathologic properties of the tumor were compatible with chondrosarcoma, grade II-III. Immunohistochemically, malignant cells were strongly and diffusely positive for S100 and epithelial markers, and showed loss of SMARCB1 expression. IDH1/2 mutations were not detected. Following whole-body PET scan, a 7.0-cm left testicular mass was discovered and diagnosed as seminoma with syncytiotrophoblastic cells, stage pT3NXM1b. Extensive retroperitoneal, mediastinal, and supraclavicular lymphadenopathy was also noticed. Histopathologic examination of the left supraclavicular lymph node revealed metastatic seminoma. By FISH, most metastatic nodal seminoma cells harbored 1 to 4 copies of isochromosome 12p, while the chondrosarcoma featured duplication of 12p. Presence of a malignant TGCT with disseminated supradiaphragmatic lymphadenopathy, the unique immunophenotypic properties of the skull-based chondrosarcoma and lack of IDH1/2 aberrations with gain of 12p strongly support the diagnosis of STM chondrosarcoma arising from metastatic TGCT. The patient did not respond to chemotherapy and succumbed three months after diagnosis. Although exceedingly uncommon, metastasis to the head and neck may occur in patients with TGCT. This case of STM chondrosarcoma demonstrated divergent immunophenotypic and molecular characteristics compared to "typical" examples of head and neck chondrosarcoma. High index of suspicion is advised regarding the diagnosis of lesions that present with otherwise typical histomorphology but unexpected immunohistochemical or molecular features.

BACKGROUND Limited research has been conducted on laparoscopic partial nephrectomy for kidney tuberculosis. This study aimed to evaluate the effectiveness of the skirted continuous suture technique in laparoscopic partial nephrectomy for localized renal tuberculosis. MATERIAL AND METHODS Five patients with kidney tuberculosis underwent standard retroperitoneal laparoscopic partial nephrectomy after computed tomography evaluation. The skirted continuous suture technique was utilized during the procedure. This retrospective study analyzed the outcomes of these patients who received treatment between January 2011 and December 2020 at Beijing Tsinghua Changgung Hospital and Eighth Medical Center of Chinese People's Liberation Army General Hospital. RESULTS The surgical success rate was 100%. Renal function was well preserved, with a decrease of glomerular filtration rate by 9.6±9.0 ml/min. Only 1 patient experienced postoperative urinous infiltration and lymphatic fistula, while the others did not have any surgical complications. Antituberculous therapy was continued postoperatively, and 1 patient had recurrence during follow-up. CONCLUSIONS The laparoscopic continuous suturing technique offers a reliable and straightforward method for extensively closing incision edges of the renal parenchyma in laparoscopic surgery. It contributes to the improved efficacy and safety of treating localized renal tuberculosis with exceptional application.
