Clinical aspects and therapeutic strategy in a case of urinary bladder endocervicosis.

The diagnostic complexities posed by lesions within the urinary bladder underscore the need for personalised management approaches. Endocervicosis, a rare condition stemming from Müllerian tissue, is characterised by the benign infiltration of endocervical glands, predominantly affecting the urinary bladder. Despite the absence of definitive symptoms, meticulous preoperative assessment is imperative to ensure precise diagnosis and optimal surgical intervention. While typically benign, recent cases have hinted at a potential association with adenocarcinoma, underscoring the necessity for meticulous management. The management of endocervicosis lacks consensus, with suggested surgical modalities including transurethral resection or partial cystectomy. In this case, a 47-year-old woman presented to our department with chronic pelvic pain following hysterectomy for adenomyosis. Imaging tests revealed a solid lesion situated at the dome of the urinary bladder. Consequently, a segmental cystectomy with circular tumour-only excision, with minimal free surgical margins, was undertaken to preserve bladder integrity. Histopathological analysis confirmed the diagnosis of endocervicosis. While the reported cases of urinary bladder endocervicosis remain limited, this instance contributes valuable insights into its understanding and management. It underscores the pivotal role of accurate diagnosis and tailored surgical intervention in optimising patient outcomes and mitigating postoperative complications, with tumour-only excision emerging as a promising and feasible approach.

Unveiling the challenges of UTUC biopsies and cytology: insights from a global real-world practice study.

PURPOSE: Diagnostic ureteroscopy (dURS) is optional in the assessment of patients with upper tract urothelial carcinoma (UTUC) and provides the possibility of obtaining histology. METHODS: To evaluate endoscopic biopsy techniques and outcomes, we assessed data from patients from the CROES-UTUC registry. The registry includes multicenter prospective collected data on diagnosis and management of patients suspected having UTUC. RESULTS: We assessed 2380 patients from 101 centers. dURS with biopsy was performed in 31.6% of patients. The quality of samples was sufficient for diagnosis in 83.5% of cases. There was no significant association between biopsy techniques and quality (p = 0.458). High-grade biopsy accurately predicted high-grade disease in 95.7% and high-risk stage disease in 86%. In ureteroscopic low-grade tumours, the prediction of subsequent low-grade disease was 66.9% and low-risk stage Ta-disease 35.8%. Ureteroscopic staging correctly predicted non-invasive Ta-disease and ≥ T1 disease in 48.9% and 47.9% of patients, respectively. Cytology outcomes did not provide additional value in predicting tumour grade. CONCLUSION: Biopsy results adequately predict high-grade and high-risk disease, but approximately one-third of patients are under-staged. Two-thirds of patients with low-grade URS-biopsy have high-risk stage disease, highlighting the need for improved diagnostics to better assess patient risk and guide treatment decisions. CLINICAL TRIAL REGISTRATION: The study was registered at ClinicalTrials.gov (ClinicalTrials.gov NCT02281188; https://clinicaltrials.gov/ct2/show/NCT02281188 ).

Impact of previous malignancy at diagnosis on oncological outcomes of upper tract urothelial carcinoma.

BACKGROUND: The evidence of prognostic factors and individualized surveillance strategies for upper tract urothelial carcinoma are still weak. OBJECTIVES: To evaluate whether the history of previous malignancy (HPM) affects the oncological outcomes of upper tract urothelial carcinoma (UTUC). METHODS: The CROES-UTUC registry is an international, observational, multicenter cohort study on patients diagnosed with UTUC. Patient and disease characteristics from 2380 patients with UTUC were collected. The primary outcome of this study was recurrence-free survival. Kaplan-Meier and multivariate Cox regression analyses were performed by stratifying patients according to their HPM. RESULTS: A total of 996 patients were included in this study. With a median recurrence-free survival time of 7.2 months and a median follow-up time of 9.2 months, 19.5% of patients had disease recurrence. The recurrence-free survival rate in the HPM group was 75.7%, which was significantly lower than non-HPM group (82.7%, P = 0.012). Kaplan-Meier analyses also showed that HPM could increase the risk of upper tract recurrence (P = 0.048). Furthermore, patients with a history of non-urothelial cancers had a higher risk of intravesical recurrence (P = 0.003), and patients with a history of urothelial cancers had a higher risk of upper tract recurrence (P = 0.015). Upon multivariate Cox regression analysis, the history of non-urothelial cancer was a risk factor for intravesical recurrence (P = 0.004), and the history of urothelial cancer was a risk factor for upper tract recurrence (P = 0.006). CONCLUSION: Both previous non-urothelial and urothelial malignancy could increase the risk of tumor recurrence. But different cancer types may increase different sites' risk of tumor recurrence for patients with UTUC. According to present study, more personalized follow-up plans and active treatment strategies should be considered for UTUC patients.

Pneumomediastinum as a rare complication in an immunosuppressed patient with emphysematous cystitis.

The extravesical spread of gas into the extraperitoneal space is an unusual complication of emphysematous cystitis and rarely, can reach remote areas of the body. Herein, we present the case of an immunosuppressed woman with emphysematous cystitis and extensive spread of extraperitoneal free gas up to the mediastinum.

European Association of Urology Section of Urolithiasis and International Alliance of Urolithiasis Joint Consensus on Retrograde Intrarenal Surgery for the Management of Renal Stones.

BACKGROUND: Retrograde intrarenal surgery (RIRS) has become the preferred treatment modality for nephrolithiasis. However, because of ongoing uncertainties regarding the optimal perioperative management, operative technique, and postoperative follow-up, as well as a lack of standardization for outcome reporting, consensus is needed to achieve more uniform clinical practice worldwide. OBJECTIVE: To develop recommendations for RIRS on the basis of existing data and expert consensus. DESIGN, SETTING, AND PARTICIPANTS: A protocol-driven, three-phase study was conducted by the European Association of Urology Section of Urolithiasis (EULIS) and the International Alliance of Urolithiasis (IAU). The process included: (1) a nonsystematic review of the literature to define domains for discussion; (2) a two-round modified Delphi survey involving experts in this field; and (3) an additional group meeting and third-round survey involving 64 senior representative members to formulate the final conclusions. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The results from each previous round were returned to the participants for re-evaluation of their decisions during the next round. The agreement threshold was set at 70%. RESULTS AND LIMITATIONS: The panel included 209 participants who developed 29 consensus statements on the following topics of interest: (1) perioperative infection management; (2) perioperative antithrombotic therapy; (3) fundamentals of the operative technique; and (4) standardized outcome reporting. Although this consensus can be considered as a useful reference for more clinically oriented daily practice, we also acknowledge that a higher level of evidence from further clinical trials is needed. CONCLUSIONS: The consensus statements aim to guide and standardize clinical practice and research on RIRS and to recommend standardized outcome reporting. PATIENT SUMMARY: An international consensus on the best practice for minimally invasive surgery for kidney stones was organized and developed by two international societies. It is anticipated that this consensus will provide further guidance to urologists and may help to improve clinical outcomes for patients.

Laparoscopic transvesical vesicovaginal fistula repair with the least invasive way: Only three trocars and a limited posterior cystotomy.

OBJECTIVE: Two conventional approaches for vesicovaginal fistula (VVF) repair are transabdominal repair for supratrigonal VVF and transvaginal approach for low lying fistulae. Laparoscopic surgery was introduced to duplicate the surgical steps of the transabdominal approach with reduction in morbidity. We report a series of patients treated with a modified laparoscopic technique which includes the use of only three trocars and a limited posterior cystotomy. METHODS: We retrospectively reviewed the data of eight patients who underwent laparoscopic VVF repair with our standardized technique from January 2015 to April 2018. Only cases with a supratrigonal fistula were included. We constantly used only three trocars. A limited 2 cm midline posterior cystotomy was performed using ultrasonic energy. A stay suture on a straight needle was passed percutaneously in the abdomen, then on either side of the cystotomy and finally was exteriorized to maintain countertraction. The cystotomy was extended downwards to include the fistula site. The fistula was dissected circumferentially to raise the bladder and vaginal flaps. The vaginal defect was closed in a transverse fashion and the cystotomy was closed vertically. RESULTS: Mean operative time was 178±31.6 min and estimated blood loss was 60±18.7 mL. Flap interposition was performed in six cases. No intraoperative complications were recorded. Mean hospital stay was 2.25±0.89 days. During hospitalization two patients experienced postoperative complications (Clavien grade I). Mean follow-up was 20.9±11.1 months (6.0-39.0 months). All patients remained continent during the follow-up period. CONCLUSIONS: This minimally invasive laparoscopic approach with only three trocars and limited posterior cystotomy provides excellent results with minimum morbidity.

Bacterial spectrum and antibiotic resistance of urinary tract infections in patients treated for upper urinary tract calculi: a multicenter analysis.

The purpose of this study is to collect information on the bacterial resistance to antibiotics of bacteria isolated from urine cultures of patients treated for upper urinary tract calculi. Data of patients with urinary tract infection and urolithiasis were retrospectively reviewed to collect information on age, gender, stone size, location, hydronephrosis, procedure of stone removal and antibiotic treatment, identification and susceptibility of pathogens, symptoms, and infectious complications. A total of 912 patients from 11 centers in 7 countries (Bulgaria, Greece, Italy, North Macedonia, Spain, and Turkey) were studied. Mean age was 54 ± 16 years and M/F ratio 322/590. Out of 946 microbial isolates, the most common were E. coli, Gram-positive, KES group (Klebsiella, Enterobacter, Serratia), Proteus spp., and P. aeruginosa. Carbapenems, piperacillin/tazobactam and amikacin showed low resistance rates to E. coli (2.5%, 7%, and 3.6%) and Proteus spp. (7.7%, 16%, and 7.4%), but higher rates were observed with Klebsiella spp., P. aeruginosa, and Gram-positive. Fosfomycin had resistance rates less than 10% to E. coli, 23% to KES group, and 19% to Gram-positive. Amoxicillin/clavulanate, cephalosporins, quinolones, and TMP/SMX showed high resistance rates to most bacterial strains. High rates of antibiotic resistance were observed in patients candidate to stone treatment from South-Eastern Europe. The empirical use of antibiotics with low resistance rates should be reserved to the most serious cases to avoid the increase of multidrug resistant bacteria. Basing on our results, carbapenems, piperacillin/tazobactam, and amikacin may be a possible option for empiric treatment of urinary stone patients showing systemic symptoms.

Small-angle X-ray scattering (SAXS) and nitrogen porosimetry (NP): two novel techniques for the evaluation of urinary stone hardness.

PURPOSE: To evaluate urinary stones using small-angle X-ray scattering (SAXS) and nitrogen porosimetry (NP). Traditionally, stones are categorized as hard or soft based on their chemical composition. We hypothesized that stone hardness is associated not only with its chemical composition but also with its internal architecture. SAXS and NP are well-known techniques in material sciences. We tested whether SAXS and NP are applicable for evaluating human urinary stones and whether they provide information at the nanoscale level that could be useful in clinical practice. METHODS: Thirty endoscopically removed urinary stones were studied. Standard techniques for stone analysis were used to determine the stone composition. SAXS was used to evaluate the solid part of the stone by measuring the crystal thickness (T) and the fractal dimension (Dm/Ds), while NP was used to evaluate the porosity of the stone, i.e., the pore radius, pore volume, and specific surface area (SSA). RESULTS: All stones were successfully analyzed with SAXS and NP. Each stone demonstrated unique characteristics regarding T, Dm/Ds, pore radius, pore volume, and SSA. Significant differences in those parameters were seen among the stones with almost identical chemical compositions. The combination of high T, high SSA, low Dm/Ds, low pore volume, and low pore radius is indicative of a hard material and vice versa. CONCLUSIONS: SAXS and NP can be used to evaluate human urinary stones. They provide information on stone hardness based on their nanostructure characteristics, which may be different even among stones with similar compositions.

Second-look Flexible Nephroscopy Combined With Holmium: Yttrium-Aluminum-Garnet Laser Lithotripsy Under Local Anesthesia: A Prospective Study.

OBJECTIVE: To present a prospectively studied series of patients who underwent second-look flexible nephroscopy combined with holmium:yttrium-aluminum-garnet (Ho:YAG) laser lithotripsy under local anesthesia for residual stone removal after percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS: Thirty consecutive eligible patients who underwent a PCNL procedure in the previous 48-96 hours were included. The inclusion criteria were the following: (1) 1 or 2 residual stones 0.8-1.5 cm in diameter and (2) age >18 years. Approximately 15 mL of a 2% solution of lidocaine hydrochloride was injected through the nephrostomy tube, which was then clamped for 15 minutes. Flexible nephroscopy was combined with Ho:YAG laser lithotripsy set at 0.8 Joules and 8 Hz. Patients were asked to rate their pain intensity using the numeric rating scale (NRS). RESULTS: There were 14 (46.7%) men and 16 (53.3%) women in the study, with a mean age of 45.2 ± 17.5 years. Twenty-one (70%) patients had 1 stone and 9 (30%) had 2 stones needing fragmentation. Twenty-eight (93.3%) patients successfully underwent the procedure under local anesthesia. The mean NRS value was 1.39 ± 1.08 (range 0-5). For the entire group, there was a statistically significant difference between those patients with 1 stone vs 2 stones needing fragmentation (NRS scores of 1.1 ± 0.77 vs 2.1 ± 1.36, respectively, P = .033). Operative time >30 minutes was associated with higher NRS score. The stone-free rate under local anesthesia was 86.7%. CONCLUSION: For patients with a minimal to moderate residual stone burden after PCNL, second-look flexible nephroscopy can be combined with Ho:YAG laser lithotripsy using only local anesthesia.

Radiological findings and the clinical importance of megacalycosis.

OBJECTIVE: To describe the radiological findings and the clinical importance of megacalycosis. MATERIALS AND METHODS: On the basis of a case report and literature review, diagnostic criteria and clinical significance of megacalycosis are presented. RESULT: Megacalycosis is mostly asymptomatic and is usually discovered either accidentally or as a result of its complications, such as stone formation, flank pain, hematuria, infection, and fever. The renal pelvis, infundibulum, and ureter are not dilated. Calyces have a semilunar configuration rather than the conventional triangular or conical form. The tip of each pyramid is flat, and the calyces possess neither fornix nor papillae impressions. The number of calyces is increased compared to the healthy condition, typically from 20-25. The renal parenchyma has a normal width but with a slight narrowing of the renal medulla. The kidney exhibits normal function, in particular with respect to its ability to concentrate the urine. CONCLUSION: Megacalycosis is a rare, usually unilateral dilatation of the kidney calyces in the presence of a normal, undilated renal pelvis and ureter. Its pathological significance lies in the occurrence of complications.

Simultaneous laparoscopic management of ureteropelvic junction obstruction and renal lithiasis: the combined experience of two academic centers and review of the literature.

INTRODUCTION: Approximately one out of five patients with ureteropelvic junction obstruction (UPJO) present lithiasis in the same setting. We present our outcomes of simultaneous laparoscopic management of UPJO and pelvic or calyceal lithiasis and review the current literature. METHODS: Thirteen patients, with a mean age of 42.8±13.3 years were diagnosed with UPJO and pelvic or calyceal lithiasis. All patients were subjected to laparoscopic dismembered Hynes-Anderson pyeloplasty along with removal of single or multiple stones, using a combination of laparoscopic graspers, irrigation, and flexible nephroscopy with nitinol baskets. RESULTS: The mean operative time was 218.8±66 minutes. In two cases, transposition of the ureter due to crossing vessels was performed. The mean diameter of the largest stone was 0.87±0.25 cm and the mean number of stones retrieved was 8.2 (1-32). Eleven out of 13 patients (84.6%) were rendered stone-free. Complications included prolonged urine output from the drain in one case (Clavien grade I) and urinoma formation requiring drainage in another case (Clavien grade IIIa). The mean postoperative follow-up was 30.2 (7-51) months. No patient has experienced stone or UPJO recurrence. CONCLUSION: Laparoscopy for the management of UPJO along with renal stone removal seems a very appealing treatment, with all the advantages of minimally invasive surgery. Concomitant renal stones do not affect the outcome of laparoscopic pyeloplasty, at least in the midterm. According to our results and the latest literature data, we advocate laparoscopic management as the treatment of choice for these cases.

Can Tumor Necrosis Factor- α and Interleukin-6 Be Used as Prognostic Markers of Infection following Ureteroscopic Lithotripsy?

Introduction. Ureteroscopic lithotripsy (URS) although highly effective for the treatment of ureteral stones is associated with certain complications, the more common of which are postoperative fever and infection. In the present study we aimed to evaluate the levels of serum cytokines in patients undergoing ureteroscopic lithotripsy and investigate any possible correlation between levels of cytokines and infectious complications after URS. Materials and Methods. Thirty patients (19 males, 11 females), with a mean age of 47 (range: 26-68) that underwent URS lithotripsy for ureteral stones, and 10 healthy volunteers serving as the control group were enrolled in this study. Serum samples for TNF- α and IL-6 were obtained before surgical intervention and after 1, 24, and 48 hours and 2 , 24, and 48 hours, respectively. The preoperative and postoperative levels were compared and correlated with the possible complications after URS. Results. Serum TNF- α levels were statistically significant, increased 1 hour (P = 0.0083) and 48 hours (P < 0.001) after operation. IL-6 levels were found statistically significant, elevated after 2 and 24 hours from the URS (P < 0.001). In 2 patients we observed postoperative fever (>38.5°C). These two patients had high preoperative values of TNF- α and IL-6 ( 30 and 50 pg/mL, resp.) and these values increased postoperatively. Conclusion. High preoperative levels of serum TNF- α and IL-6 may indicate a predisposition for postoperative inflammation and infection following URS lithotripsy.

Metastatic Mucinous Adenocarcinoma of the Prostate with PSA Value of 8.6 ng/mL at 5-Year-Followup after Prostatectomy, Radiotherapy, and Androgen Deprivation.

Introduction. Mucinous adenocarcinoma of the prostate is a rare variant of prostate cancer. Its malignant potential and the clinical course of the affected patients remain, by and large, controversial. No data exist about the course of metastatic mucinous adenocarcinoma of the prostate. Case Presentation. This case report describes the excellent clinical course of a 68-year-old patient with metastatic mucinous adenocarcinoma of the prostate, treated by radical prostatectomy, irradiation, and androgen deprivation. Conclusion. In our case, mucinous adenocarcinoma of the prostate does not appear to behave differently than acinar prostate cancer. Its malignant potential is dependent on its Gleason score.

The use of a perimeatal-based penile skin flap to cover the repair of a tubularized incised plate urethroplasty: from experimental surgery to clinical practice.

OBJECTIVE: To prospectively evaluate the efficacy and safety of a perimeatal-based penile skin flap for neourethral coverage after repair of distal hypospadias with tubularized incised plate urethroplasty (TIPU). METHODS: In 12 New Zealand white rabbits a ventral urethral defect was created and reconstruction was accomplished with continuous suture. An epithelialized defect-based flap was harvested from the penile skin to cover the repaired defect. The animals were euthanized on the 28th postoperative day and their penises were processed for microscopic examination. In 32 children with distal hypospadias a TIPU was performed. A penile skin flap was created immediately below the distal end of the neourethra and used to cover the urethroplasty. RESULTS: Histological examinations revealed complete restoration of continuity of the stratified squamous epithelium without evidence of inflammation or fistula formation with full consistency with the underlying papillary reticular and corium. There were no cases of fistula formation. One patient developed meatal stenosis. All patients had a satisfactory cosmetic appearance and excellent functional results. CONCLUSION: The formation of a perimeatal-based skin flap is a simple and safe method of providing additional cover for the constructed neourethra after TIPU, minimizing the fistula rate.

Ureteroscopic laser treatment of upper urinary tract urothelial cell carcinomas: can a tumour free status be achieved?

Introduction. In cases of anatomic or functional single kidney with urothelial tumours of the upper urinary tract, the endoscopic laser ablation has proven efficacious. Based on the knowledge that low-grade, low-stage upper tract transitional cell carcinomas rarely progress to invasive lesions, indications for endoscopic laser ablation have expanded to include patients with bilateral functioning kidneys and low-grade tumours. The question that remains to be answered is whether endoscopic laser ablation has the ability to completely eradicate upper urinary tract tumours. Methods. We performed in 25 patients in a period of 11 years 288 ureteroscopies and, if needed, laser ablation of upper urinary tract tumours in imperative indication. Results. In 32% of the patients the cancer remained even after several laser sessions. 64% of patients were tumour free after one or more laser sessions but remained clear only for the next 3 months. Only 1 patient was tumour free for a period of 68 months after 1 session of laser treatment. The procedure had low complication rates. Conclusion. The laser technology and the introduction of small diameter semirigid and flexible ureteroscopes made ablation of upper urinary tract tumours possible and safe. Nevertheless a complete resection of the carcinomas is rarely possible.

Mismatch repair hMSH2, hMLH1, hMSH6 and hPMS2 mRNA expression profiles in precancerous and cancerous urothelium.

Changes in the expression of the mismatch repair (MMR) genes hMSH2, hMLH1, hMSH6 and hPMS2 reflect dysfunction of the DNA repair system that may allow the malignant transformation of tissue cells. The aim of the present study was to address the mRNA expression profiles of the mismatch DNA repair system in cancerous and precancerous urothelium. This is the first study to quantify MMR mRNA expression by applying quantitative real-time PCR (qPCR) and translate the results to mRNA phenotypic profiles (r, reduced; R, regular or elevated) in bladder tumors [24 urothelial cell carcinomas (UCCs) and 1 papillary urothelial neoplasm of low malignant potential (PUNLMP)] paired with their adjacent normal tissues (ANTs). Genetic instability analysis was applied at polymorphic sites distal or close to the hMSH2 and hMLH1 locus. Presenting our data, reduced hMSH2, hMSH6 and hPMS2 mRNA expression profiles were observed in cancerous and precancerous urothelia. Significantly, the ANTs of UCCs revealed the highest percentages of reduced hMSH2 (r(2)), hMSH6 (r(6)) and hPMS2 (p(2)) mRNA phenotypes relative to their tumors (P<0.03). In particular, combined r(2)r(6) (P<0.02) presented a greater difference between ANTs of low-grade UCCs vs. their tumors compared with ANTs of high-grade UCCs (P= 0.000). Reduced hMLH1 (r(1)) phenotype was not expressed in precancerous or cancerous urothelia. The hMSH6 mRNA was the most changed in UCCs (47.8%), while hMSH2, hMLH1 and hPMS2 showed overexpression (47.8, 35 and 30%, respectively) that was associated with gender and histological tumor grading or staging. Genetic instability was rare in polymorphic regions distal to hMLH1. Our data reveal a previously unrecognized hMSH2 and hMSH6 mRNA combined phenotype (r(2)r(6)) correlated with a precancerous urothelium and show that hMLH1 is transcriptionally activated in precancerous or cancerous urothelium. In the present study, it is demonstrated that reduction of hMSH6 mRNA is a frequent event in bladder tumorigenesis and reflects a common mechanism of suppression with hMSH2, while alterations of hMSH2 or hMLH1 mRNA expression in UCCs does not correlate with the allelic imbalance of polymorphic regions harboring the genes.

Laparoscopic transvesical resection of an en bloc bladder cuff and distal ureter during nephroureterectomy.

OBJECTIVE: The most appropriate technique for excising the distal ureter and bladder cuff during laparoscopic nephroureterectomy is still debated. We report our experience with a pure laparoscopic transvesical method that duplicates the long-standing open transvesical approach. MATERIALS AND METHODS: Seven men and three women diagnosed with upper tract transitional cell carcinoma were treated with this procedure. Three intravesical ports were inserted, and pneumovesicum was established at 12 mmHg. Transvesical laparoscopic circumferential detachment of the bladder cuff and en bloc mobilization of the last centimeters of the distal ureter were performed, followed by the closure of the bladder defect. Subsequently, a nephrectomy was performed either laparoscopically or using an open flank approach. RESULTS: The median age was 68.5 years. The procedure was completed uneventfully in all cases. The median operating time for distal ureter excision was 82.5 minutes (range 55-120). No complications directly related to the pneumovesicum method were recorded. The median follow-up period was 31 months (range 12-55). During the follow-up period, two patients (20%) died from the disease, and a bladder tumor developed in three cases (30%). CONCLUSION: The laparoscopic transvesical resection of the en bloc bladder cuff and distal ureter is a reliable, effective, and oncologically safe technique, at least in the midterm.

Single inguinal node metastasis of stage I testicular seminoma shown by scrotal scintigraphy, 6 months following radical orchiectomy.

Lymphatic drainage of the testes is known to follow a predictable pathway that usually involves the retroperitoneal, paraaortic, paracaval and interaortocaval nodal chains. Herein we report the case of a 41 years old man with a stage I testicular seminoma, with an unexpected inguinal lymph node metastasis. During his routine follow-up visit, 6 months after radical orchiectomy, a spherical mass in the right inguinal region was palpated. Thoraco-abdominal CT did not reveal any evidence of retroperitoneal enlarged lymph nodes or distant metastases, but showed a 2cm right inguinal mass. Scrotal scintigraphy with technetium-99m pertechnetate was performed in order to evaluate the local vascularity of the right inguinal area. The angiographic phase (0-1min) and the blood pool images at 15, 30, 45 and 60min revealed high uptake in the right inguinal region, suggesting a hyperemic mass suspicious for tumor recurrence. The excised mass was found to be an enlarged lymph node infiltrated with seminoma. The patient received adjuvant radiotherapy to which he showed a complete response and has been disease free at 2 years follow-up. In conclusion, in the case presented scrotal scintigraphy showed a hyperemic mass at the right inguinal region that proved to be the sentinel node of a stage I testicular seminoma and was treated accordingly.

Minimal invasive treatment options in pregnant women with ovarian vein syndrome.

PURPOSE: To describe the treatment modalities of symptomatic ovarian vein syndrome in pregnancy. METHODS: In our study, we included 12 pregnant women with right ureter and kidney dilatation; caused by ureteric obstruction. In 11 out of 12, we insert a DJ stent and in one woman we applied percutaneous nephrostomy, because of intermittent abdominal pain, resistant on analgetic therapy or feverish pyelonephritis. DJ stents and nephrostomy were inserted under ultrasound guidance without anaesthesia. RESULTS: After insertion of DJ stents, respective percutaneous nephrostomy colic attacks went back immediately and the feverish pyelonephritis in few days. At no time during these procedures, there was a risk for pregnancy. CONCLUSION: Ovarian vein syndrome in pregnancy can lead to violent colic pain and can become complicated by accompanied pyelonephritis. In these cases insertion of a DJ stent or percutaneous nephrostomy under ultrasound guidance is possible and safe, and leads to an improvement of complaints immediately.
