Renal calyceal diverticulum mimicking a large renal cyst-A case report

Renal calyceal diverticulum are outpouching from renal calyx or pelvis into the renal cortex lined by transitional cell epithelium. We report a case of 35 years old male with history of accidental fall from bike, who presented with persistent right loin pain and hematuria. CT Urogram showed multiple large right renal cysts (BOSNIAK II). Patient was planned laparoscopic renal cyst deroofing. Due to suspicion of calyceal diverticulum, an intraoperative Retrograde Pyelogram (RGP) was done which showed calyceal diverticulum. Laparoscopic calyceal diverticulotomy with closure of communication was done. If only a cyst deroofing was done considering the CT finding alone, it would have ended up in post-operative complication of urinoma which may require a re-surgery. This case report emphasizes the importance of anticipating calyceal diverticulum and intraoperative attempts in the form of doing RGP to identify calyceal diverticulum which mimic renal cyst regardless of CT finding in suspected cases. Keywords: Calyceal diverticulum; large renal cyst; retrograde pyelogram; laparoscopic calyceal; Diverticulotomy.

Abstract Background Mucinous cystadenoma (MC) of the kidney is exceedingly rare. We found 22 similar cases in the literature. These masses are underdiagnosed due to radiologic similarities with simple renal cysts. Case presentation A 66-year-old man with a previous history of hypertension and anxiety was referred to our tertiary clinic with left flank pain. Ultrasound revealed a 60 mm-sized, complex cystic mass with irregular septa in the lower pole of the left kidney (different from last year's sonographic findings of a simple benign cyst with delicate septa). CT scan showed the same results plus calcification. Due to suspected renal cell carcinoma, a radical nephrectomy was performed. Postoperative histopathologic examination revealed a cyst lined by a single layer of columnar mucin-producing cells with small foci of pseudo-stratification, consistent with the MC’s diagnosis. The first follow-up visit showed normal blood pressure without medication and no flank pain and anxiety after a month. Conclusion It is quite challenging to distinguish the primary MC of the kidney from a simple renal cyst based on clinical and imaging findings. The radiologic features of these entities overlap significantly. Thus, complex renal cyst and renal cysts with mural nodules should be followed closely to detect malignancy earlier.

Solitary renal cysts are relatively common. The occurrence of transitional cell carcinoma (TCC) in a renal cyst is rare. We present the case of a 59-year-old man with a medical history of viral hepatitis B. During a workup for his hepatitis, a computed tomography scan revealed a large cystic tumour in the upper region of the left kidney. A radical left nephrectomy was performed. Microscopic examination of the cystic tumour revealed a grade 2 TCC. The cyst was lined by transitional epithelium. This is a case of a TCC growing within a renal calyceal cyst.

Retroperitoneal Laparoscopy

Abstract Background: Under the constraints of the increasingly tight medical environment and cost, day surgery mode has become a favorable trend and attracts attention from clinicians. Currently, there are no standards or procedures on the retroperitoneal laparoscopy for unilateral simple renal cyst decortication in day surgery mode. We attempted to investigate the feasibility and safety criteria of unilateral simple renal cyst decortication by retroperitoneal laparoscopy in the day surgery ward and to compare the advantages and the disadvantages with conventional inpatient ward mode.Methods: A total of 41 patients with unilateral simple renal cysts meeting surgical indications were enrolled in this study. To see whether patients in the day group could successfully complete the procedure and be admitted and discharged within 24 hours and to summarize the advantages and the advantages. The indexes of the operation time, time of hospitalization, postoperative complication rate, total costs of hospitalization and other indicators were compared between the two groups.Results: 41 cases of unilateral simple renal cyst decortication were completed successfully. Patients were followed up 10-12 months after surgery. The results of time of hospitalization, total costs of hospitalization and time of postoperative removal of drainage tube were statistically significant between the two groups of the day ward group and the inpatient ward group (P <0.05). Conclusions: We concluded the retroperitoneal laparoscopy for unilateral simple renal cyst decortication in patients with unilateral renal cysts was safe and feasible in day surgery mode under certain indicative criteria. The criteria included patients’ age between 40 and 80 years, no previous history of abdominal surgery, CT showing a unilateral renal cyst (Bosniak I or II), preoperative ASA assessment was I or II, no contraindications to surgery or anesthesia, postoperative team management and discharge assessment. Advantage of reducing time of hospitalization and total medical cost may relieve the situation of the shortage of medical resources.

Male patient 46 years of age presented with history of Laparoscopic A-H pyeloplasty with DJ stenting for left side hydronephrosis due to PUJ obstruction. After stent removed he experienced intermittent flank pain, discomfort with fullness sensation. On examination there was mild left renal angle tenderness. Urinalysis showed RBC. USG revealed moderate left hydronephrosis. CT urogram showed left side gross HDN with 5 mm PUJ stone. Tc-99m DTPA renal scan revealed partial obstruction. After counseled and exploration founded an impacted PUJ stone. During removal of PUJ stone, identified a suture material embedded by the stone. After removed the stone,PUJ still narrowed. Then A- H pyeloplasty done with placed a D-J stent in situ. The patient had a good post-operative recovery. Bangladesh Journal of Urology, Vol. 21, No. 2, July 2018 p.164-165

Simple renal cysts are among the most common cystic lesions of the kidney. Renal cysts most often remain asymptomatic, but rarely these cysts may become huge in size and result in significant symptoms. Giant renal cysts present a technical challenge in terms of surgical management. Although laparoscopic procedures have been performed successfully at experienced centres, intraperitoneal marsupialization via open approach may be a feasible option at less experienced centres. We report a case of a young female with a giant (24 × 18 cm) renal cyst of Bosniak type-II variety. De-roofing and intraperitoneal marsupialization of the cyst was performed. At the 1-year follow-up, she was asymptomatic, with no residual cyst.

Background: Infection with Mycobacterium tuberculosis (TB) is one of the major causes of mortality in developing countries. TB is primarily a lung disease, but can affect almost every organ of the body. Skeletal TB involves the bones or joints. In this report, we will introduce a patient with a medical history of transitional cell carcinoma (TCC) of the bladder that presented with spinal tuberculosis (Pott's disease). Case Report: The patient was a 74-year-old man with medical history of TCC of the bladder who had come to hospital due to severe weakness and sprains of lower extremities. Other symptoms noted by the patient included anorexia, weight loss (of 5 kg), and night sweats, but he did not complain of fever, coughs or respiratory symptoms. The lab data were as follows: WBC, 16/9*103; ESR, 88 mm/hr; CRP, 78mg/dl. Radiology findings revealed degenerative process in the L2-L3 lumbar vertebrae and disk. PCR and sample tissue culture results showed the presence of Mycobacterium tuberculosis. Conclusion: In the lesions of the lumbar vertebrae, even if there is another underlying disease, spinal TB should also be considered as a possibility. Furthermore, in patients with any type of cancer, any other organ conflict is not considered as metastasis, and tissue sampling should be provided because a change in the type of disease can influence prognosis.
